Establishing Perovskite Bankability with Accelerated Testing and Energy Yield Analysis
9:25 AM
Adam Lorenz
Perovskite technology continues to mature, with several pilot manufacturing lines being deployed around the globe, but have yet to make large-scale commercial impact due to the lack of bankable demonstrations and relevant Product Qualification Programs (PQPs) to ensure customer confidence. Since perovskite devices exhibit unique responses to light, heat and bias compared to silicon PV, there is a need to move beyond traditional JV measurements and light soaking stations to predict and model how perovskites will perform in real world conditions. This presentation will highlight how CubicPV is employing multifactorial accelerated stress testing in custom-built test chambers known as "PV Bake Ovens" to study field-relevant perovskite behaviors. These tests highlight how changes to perovskite architecture can influence responses to diurnal cycling of light and heat, temperature coefficient, and degradation rate which all contribute to predicted energy yield. These accelerated tests are correlated with outdoor performance data and used to predict field degradation rates and address real world challenges behind perovskite solar cells.

Four Terminal Tandem Strategy for Perovskite
9:45 AM
Dr. Bin Fan
The efficiency improvement in tandem solar cells is driven primarily by the perovskite sub-cell. Technology development should, therefore, be carried out in a way that aligns with the properties of perovskite materials. In this presentation, we will discuss why we have chosen a four-terminal architecture rather than a two-terminal one for mass production, and provide a detailed introduction to how the four-terminal architecture can be applied in both utility-scale power plants and residential scenarios.

Outlook for Four-Terminal Perovskite Tandem Technology
10:05 AM
Yang Chen
This talk will present the latest progress of Microquanta Semiconductor’s four-terminal perovskite tandem technology, focusing on its technical advantages, industrial readiness, and application potential. The four-terminal architecture allows the perovskite top cell and silicon bottom cell to operate independently, offering greater flexibility in system design, improved stability, and a practical pathway toward commercialization. The presentation will highlight how this technology can deliver high energy output in applications where installation area is limited, while also creating new opportunities in building-integrated photovoltaics (BIPV), where efficiency, transparency, color customization, and architectural integration can be combined in a single solution. Current product progress, field deployment experience, and future development directions for four-terminal tandem modules will also be discussed.

Realizing the full potential of Perovskite PV with High-Speed Roll-to-Roll Production
11:00 AM
Thomas Tombs
Perovskite (PVK) technology will dramatically change the solar industry in the next few years. What is the optimum path forward and endgame for PVK photovoltaics? Are PVK-silicon tandems a winning combination or an attempt to prolong an enormous silicon PV manufacturing infrastructure? Roll-to-roll equipment has a long history of enabling low-cost, high-quality production and routinely exceeds 90% uptime and yield. When speeds exceed 30 mpm the cost of capital, energy, and labor become very small and the product cost approaches the cost of the materials. This presentation shows how EMC optimizes the cost benefits of high-speed production of PVK PV, and how we plan to enable local, low energy usage production of high-performance PVK photovoltaic modules. PVK single junction and PVK-PVK tandem devices made at high speed will be compared to low-speed production of PVK, CdTe, and silicon modules.

To meet the urgent demand for carbon-neutral energy, solar electricity generation must scale dramatically. Perovskite photovoltaics play a critical role in this transition by (a) boosting the efficiency of established technologies like silicon-based solar cells and (b) enabling low-cost, energy-efficient fabrication of lightweight, flexible PV devices ideal for applications that require adaptable shapes and forms.
Successful commercialization of perovskite solar cells depends on the availability at industrial scale of specialized interface materials exhibiting optimized electronic, physical, and chemical properties. These materials need to enable high power conversion efficiency as well as robust stability under light exposure, elevated temperatures, and mechanical stress.
This presentation will describe the engineering of fullerenes as electron transport materials (ETMs) for interlayers in n-i-p, p-i-n, and tandem perovskite device architectures. We will cover the production and refinement of unfunctionalized fullerenes - particularly C60 - produced at industrial volumes for vapor-phase deposition. The role of functionalized fullerene moieties capable of forming self-assembled monolayers (SAMs) and/or stabilizing the perovskite crystal phase will also be described. We will detail the development and synthesis of advanced fullerene derivatives incorporating groups such as phosphonic acid or amino/ammonium functionalities which enable effective interface passivation, supported by corresponding device performance results.
We will also discuss our ongoing efforts to develop advanced hole transport materials (HTMs). New and existing targets are optimized around triphenylamine or carbazole cores and functionalized with phosphonic groups to achieve optimal electronic characteristics. Emerging strategies, including cross-linking approaches and the presence of more than one functional group, will be highlighted as means to enhance both the quality and long-term durability of interface layers.
Performance data from n-i-p and p-i-n single-junction devices as well as tandem configurations, will be shared to illustrate these advancements. The selection of solvents suitable for large-scale manufacturing will be discussed.

Development of Printable Indium Tin OxideI(TO) Nano Inks for Low-Temperature Transparent Conductive Films
Maryam Bari
This work presents the development of printable Indium Tin Oxide (ITO) nano inks designed for low-temperature fabrication of transparent conductive films. Conventional ITO deposition relies on high-temperature and vacuum-based processes, limiting compatibility with flexible substrates and increasing manufacturing cost and energy consumption. In this study, we introduce a solution-processed ITO nano ink with controlled particle size, stable dispersion, and optimized rheology for scalable coating techniques such as spin coating and slot-die coating. The resulting films demonstrate high optical transparency, good electrical conductivity, and uniform morphology at processing temperatures below 150 °C. This approach enables a cost-effective and energy-efficient pathway for producing transparent conductive layers in next-generation electronics, including photovoltaics, displays, and printed devices

Stable Organic Hole Transport Layer for Solar Cells
Feng Wang
Here, I will introduce new Spiro-OMeTAD inks with several unique advantages that can significantly enhance the efficiency and stability of next-generation solar panels. Specifically, the resulting Spiro-OMeTAD films exhibit excellent moisture and thermal stability, even after aging under 85% relative humidity and at 85 °C. Large-area films fabricated using printing techniques show high uniformity. In addition, the films can be used directly without any post-oxidation process in air. Moreover, the films can suppress Au migration into the perovskite layer, further improving device stability.

An ITO free micro-groove architecture for low cost scalable perovskite modules
4:25 PM
Neil Spann
Perovskite photovoltaics have demonstrated rapid efficiency gains, yet large-scale adoption remains constrained by manufacturing cost, material availability, and integration into lightweight or non-traditional substrates. This presentation explores a scalable, ITO free, device architecture and manufacturing approach designed to address these constraints through ultra-low material usage and compatibility with high-throughput roll-to-roll production.
The talk will focus on a micro-structured substrate architecture that enables efficient charge collection using no ITO/TCO, eliminating reliance on scarce or geopolitically constrained inputs. By decoupling electrical performance from thick transparent conductive layers, this approach supports flexible, lightweight photovoltaic films suitable for large-area deployment.
Experimental results demonstrating leading bifacial results, improved angular and shading response and resistance to pin holes will be presented.
The session will conclude with a discussion of how such architectures may enable cost-competitive perovskite photovoltaics at scale, while improving supply-chain resilience and opening new application spaces beyond conventional rigid modules.

Sandra Wiegman
As perovskite solar manufacturing accelerates toward industrial scale, Spatial ALD is becoming a key enabler of high‑performance, stable, and cost‑competitive devices. This presentation highlights how Kalpana Systems’ first commercial roll‑to‑roll Spatial ALD platform addresses critical production challenges—from defect control to encapsulation quality—while delivering the throughput and uniformity required for true gigawatt‑scale manufacturing. We show how Spatial ALD directly enhances device efficiency and durability, lowers total cost of ownership through high uptime and low precursor use, and provides a clear pathway to high‑volume perovskite production. With its commercial system now deployed, Kalpana Systems is setting the benchmark for scalable, industry‑ready roll-to-roll Spatial ALD.

Homerun - A fully integrated value chain to Perovskite production
5:05 PM
Luca Sorbello
Perovskite photovoltaics are rapidly moving from laboratory breakthrough to industrial reality. In this keynote, we shift the discussion from individual technologies to a fully integrated photovoltaic value chain—linking silica sand resources, solar glass manufacturing, silicon PV production, and perovskite processing into a unified industrial ecosystem.
The talk presents a strategic approach to building next-generation solar manufacturing by combining established crystalline silicon infrastructure with emerging perovskite technologies within a coordinated industrial framework. By controlling key upstream materials—starting from high-purity silica for solar glass and wafers—and integrating advanced device manufacturing, the photovoltaic sector can strengthen supply chain resilience, regional industrial capacity, and energy security in an increasingly complex geopolitical landscape.
This vertically integrated model enables the rapid deployment of new photovoltaic products across multiple markets, including building-integrated photovoltaics (BIPV), building-applied photovoltaics (BAPV), lightweight IoT energy panels, and next-generation high-efficiency modules for distributed and utility-scale applications.
Through the “Homerun” case study, we illustrate how a coordinated “silica-to-panel” manufacturing strategy can create a scalable and competitive ecosystem for advanced photovoltaics. The keynote highlights how integrating materials, manufacturing, and device innovation can support industrial sovereignty, accelerate deployment, and strengthen the role of photovoltaics in a secure and resilient energy future.

From Lab to Fab: Scaling and deployment of 1x2m perovskite at Caelux – wins and remaining challenges
Ernest Hasselbrink
Caelux is manufacturing full-size (approximately 1x2m) perovskite “active glass” for 4T tandems with up to 16.5% PCE perovskite and an expected 8.5%-9% additive contribution from the Si layer. Scaling 110cm2 lab devices by nearly 200 times to ~2m2 devices can be a significant challenge, but Caelux made three strategic decisions that helped significantly. The first was to focus lab-scale effort on material systems meant only for 4T application, and only using processes and tools that are scaled-down versions of full-scale process tools. The second was to co-locate lab and fab, to keep lab and deployment teams collaborative. The third was to focus on process control and supporting information systems, which significantly reduces variability and enables rapid problem-solving. There have been many challenges as well, and there still some remaining. One is that there are few western 17025-certified labs capable of testing and certifying perovskite panels with continuous 1-sun illumination and appropriate I-V sweep times for perovskite. Another is that we need to develop a strong baseline of data validating the performance and durability of voltage-matched 4T (and 2T) tandems in the field. Metastability of the product in its early life challenges industry participants to collaborate on standards that balance industry’s desire for fast and inexpensive factory testing with customers’ needs for high confidence in product performance. Example data of outdoor testing and correlation to indoor data will be reviewed.

Pursuing bankability for perovskite/silicon tandem panels
Colin Bailie
Bankability is yet an uncertain set of requirements for perovskite technology, as no truly new technology has achieved bankability in decades. In order to achieve meaningful commercial deployment in the US and Europe, achieving bankability is a requisite.
I will discuss our latest strategy and results in trying to bridge that gap, including the combination of R&D and pilot strategy encompassing targeted accelerated lifetime testing, standardized accelerated testing, and outdoor field testing with recommendations on what has been and continues to be the most important aspects to focus on.

Perovskite tandem delivers. Mismatch steals. MLPE saves the gains.
Rafael Fleischman
Recent years have seen substantial progress in perovskite–silicon tandem research, particularly at the cell level, and the first pre‑commercial modules are now beginning to appear on the market. What remains largely unknown is how full PV systems comprising many tandem modules perform once deployed under real operating conditions. These system‑level effects are still poorly investigated.
Tandem modules are inherently more prone to module-level mismatches compared to conventional silicon modules. Over time, individual perovskite cells tend to degrade at different rates, leading to increasing mismatch within and between modules. Reproducibility-related issues during early-stage manufacturing introduce additional variability between modules. Variations in the solar spectrum affect each subcell differently, and temperature fluctuations modify the operating conditions of the perovskite and silicon layers in unequal ways. In bifacial configurations, changes in albedo further amplify these differences. Together, these factors make substantial mismatch not only possible but expected in tandem systems, far exceeding the levels typically observed in silicon-only PV arrays.
SolarEdge, drawing on its extensive experience with Power Optimizers for Module-Level Power Electronics (MLPE), is developing solutions specifically tailored to the operating characteristics of perovskite-tandem modules. By ensuring that each panel, in either 2‑terminal or 4‑terminal configurations, operates at its own maximum power point, the Power Optimizers maintain every module at their optimal operating conditions regardless of long-term aging, spectral variability, or temperature fluctuations. This provides a practical and scalable pathway to realizing the high efficiencies that tandem technology promises once deployed in real, complex systems, ensuring that these additional gains are preserved rather than lost.
This talk will highlight the main sources of mismatch unique to perovskite/Si tandems, present the SolarEdge vision and strategy for supporting these modules and discuss how MLPE can enable stable and high‑yield perovskite tandem PV systems in real installations.

A Robust Room-Temperature Synthesis of Monodisperse Tin Oxide Nanocrystals for Perovskite Solar Cells
Matthias Grotevent
Tin oxide is commonly used as an electron transport layer in perovskite solar cells and modules. Often, spin-coating and slot-die coating of tin oxide nanocrystals from colloidally dispersed inks are used, demonstrating device efficiencies above 25%. However, established colloidal syntheses often require precise control of reaction parameters and multi-step purification, posing challenges for scalable, low-cost manufacturing. Here, a room-temperature synthesis of crystalline tin oxide nanocrystals is presented that is remarkably robust — the resulting particle size and crystallinity are independent of reaction time, temperature, and precursor concentration. Unlike conventional approaches, the synthesis requires only simple mixing of precursors without precise control of fluid dynamics. After synthesis, the monodisperse nanocrystals are transferred into a nonpolar dispersion agent with an overall reaction yield exceeding 98% (relative to the tin precursor). Perovskite solar cells fabricated using these nanocrystals demonstrate competitive device efficiencies, confirming that this scalable synthesis route is directly compatible with high-performance device fabrication.

Polymeric Materials for Perovskite Module Packaging
Perovskite photovoltaic technology is advancing rapidly, creating a need for packaging solutions suitable for commercial deployment. Polymeric materials play a critical role in protecting solar cells and enabling reliable performance in outdoor environments.
Compared with conventional photovoltaic technologies, perovskites require lower-temperature packaging materials that provide exceptional moisture and oxygen barriers, strong mechanical protection, and high optical transparency. Meeting these requirements presents new challenges for material suppliers. This presentation will examine the packaging demands unique to perovskite devices, review emerging polymer solutions, and discuss the technical challenges facing material developers as the technology transitions from laboratory-scale devices to field-ready modules.

Using steady-state LED simulation to enhance performance & stability testing for commercial perovskite PV
1:40 PM
Peter Pasmans
Perovskite photovoltaics are transitioning from lab research to gigawatt-scale manufacturing, with efficiencies exceeding 27% for single-junctions and 35% for silicon tandems. However, commercialization hinges on proven long-term reliability and precise inline power characterization. Achieving a 25-year lifetime under intense light and heat requires standardized indoor testing protocols that correlate with outdoor field data. Furthermore, inherent hysteresis and metastability necessitate advanced protocols for inline characterization, while tandems require rigorous spectral matching. This work evaluates emerging standards and strategies to accelerate reliability and performance assessment, providing a roadmap for characterizing perovskite devices from R&D to mass production to ensure bankability.

New laser platform for research and pilot production enables opportunities in perovskite PV.

Stefan Bergfeld
We recently developed a new set of laser platforms for research in pilot production of perovskite solar cells and module productions. Now it is possible to process modules with up to 1 square meter size.
The optimum laser wavelength for processing perovskite solar cells depends on the particular layer and the whole layer stack. Therefore, all tools have 3 wavelengths (IR, green, and UV) in one tool. The wavelength can be changed via computer. It is also possible to process with two wavelengths at the same time. This has benefits when 2 layers need to be erased at the same time but both layers have different absorption. Or if an ablation process and a cleaning step is required at the same time.
When developing the laser processes for PSC, it is not clear from the beginning if the layers need to be processed from the glass side or from the film side. Our tool has 2 processing heads: one below the substrate for glass side ablation and over the substrate for film side ablation. The platform allows processing in both configurations to compare the results afterwards.
For research and pilot production, not high throughput is needed but the investment needs to be lower. We made one platform for several processes. Only one tool is needed for P1, P2, P3 scribing and P4, laser edge deletion (LED) or laser contact cleaning (LCC). An additional top hat IR laser can be integrated for very fast LED or a green laser for fast LCC.
To ensure high precision processing, we implemented a new scribe tracking and position correction system. This new development is precise and very cost-effective.
The tool is very flexible. Users can adapt it to new requirements themselves.
We also offer now a top hat fiber-coupled diode laser for photoluminescence (PL) for integration into our tools. To be sensitive to different band gaps, we offer 976, 808, 520, and 450 nm.
Also available are process heads for glass cutting, glass drilling, and glass welding.
We will present first results of process development and new concepts for laser interconnection like „point contacts“ or semi-transparent modules for building integrated PV (BI PV) that will be enabled with this platform.

Practical Encapsulation Factors for Reliable Perovskite Commercialization
2:20 PM
Yun-Chang Chao
Perovskite photovoltaic devices have achieved significant efficiency improvements, yet long term operational stability remains the key barrier to commercialization.
While current research primarily focuses on absorber and interface optimization, systematic discussion of encapsulation remains relatively limited, despite its strong influence on device lifetime and scalable manufacturing.
This talk explores practical encapsulation considerations observed in industrial validation projects and discusses how these factors affect device reliability and production scalability. Drawing from common industrial failure modes, we present a structured engineering perspective that connects material selection and structural design with long term performance.
Everlight Chemical has been engaged in encapsulation material development for emerging photovoltaic technologies since the DSSC era and has continuously participated in cross continental validation projects.
The encapsulation systems developed through these collaborations demonstrate improved barrier performance compared to conventional solutions.
These performance has been evaluated and validated by academic and industrial partners, with related findings published in internationally recognized journals.
By integrating field testing experience with engineering design principles, we aim to encourage further collaboration and dialogue on how encapsulation strategy can support reliable and commercially viable perovskite deployment.

Recycling Procedure of Perovskite Minimodules
3:10 PM
Cordula Wessendorf
As perovskite and perovskite-silicon tandem modules are already on the market, time is come to think about their recycling. For the year 2034 it is estimated that perovskite-silicon tandems will have 10% global market share[1] which will correspond to ~100 GW [2]. On one hand, perovskite and perovskite-silicon tandem modules contain critical materials[3] like indium in the transparent contact layers, cesium in the perovskite absorber layer or silver in the interconnection with electrically conductive adhesives (ECAs) in case for Perovskite-silicon tandem modules or they could contain silver in the back contact in case of perovskite single modules. On the other hand, approximately one third of the molecular weight of the perovskite absorber is lead. Regarding the whole module stack, the perovskite layer is only 300-600nm thick which corresponds to approximately 1 g Pb per m2 [4]. Lead is not critical in terms of abundance, but it is toxic and therefore landfill of perovskite modules must be strictly avoided to ensure that lead leakage to the environment and to the food chain is prevented.
The first publication about recycling of fully encapsulated perovskite modules was published by Chen et al. [5], but they used high temperature (250 °C). In our study, we developed an industrial-scale recycling process at 140-160°C for perovskite modules that allows >96% of the perovskite material to be recovered and reused in the manufacture of modules within the DBU funded project PeroCycle.
In addition, we could recover the indium containing TCO-coated glasses selectively and undamaged so that no intermixing with the encapsulation glass occurs and recoating after cleaning is possible. In recycling processes where solar modules are shredded, the glass fractions of substrate and encapsulation glass are mixed and crushed, resulting in downcycling. In contrast, in our study, the perovskite modules are thermo-mechanically separated in one piece, allowing the carrier glass to be reused after purification. This saves energy and material.
With our developed recycling procedure, mini-modules processed with recycled substrates and recycled PbI2 achieved >90% of the efficiency of minimodules made from fresh ITO substrates and fresh PbI2.

Efficient Structures And Processes for Upscaling of Perovskite Modules and Tandems
3:50 PM
Tom Aernouts
The unprecedented fast rise of power conversion efficiency (PCE) of perovskite-based solar cells (PSC) in recent years has created a vast worldwide research activity in this material class for photovoltaic and other opto-electronic applications. Several materials compositions and device architectures have been described and best reported PCE’s yield recently more than 27%. Also improved stability under specific conditions has been shown for specific architectures. Whereas all these results indicate a high potential for this novel solar technology, further steps must be taken to convince industry and even the whole PV community that perovskite-based photovoltaics can really emerge from the lab into industrially applicable solar module processing. Our R&D program works actively on the upscaling of perovskite solar modules with scalable processes up to sizes of 35x35 cm2.
Similarly, the perovskite PV technology has boosted the tandem research whereby perovskite cells and modules are placed on top of other PV devices like Si or CIGS solar cells. Impressive lab scale results exceeding 34% PCE have been reported. New challenges arise when this needs to be upscaled to full wafer or module size. It will be discussed how we approach these challenges.
