New Materials for Metallization and Interconnection of Perovskite Cells: Low-Temperature Processing & Reduced Silver Consumption

Norbert Willenbacher
The goal of significantly reducing CO2 emissions requires a massive expansion of PV installations worldwide. Perovskite cells offer a unique opportunity to enable this at a low consumption of precious resources and energy. This requires metallization and interconnection materials that can be processed at low temperatures. In order to avoid bottlenecks in the supply of silver for contacting and inter-connection of solar cells, the specific silver consumption in the production of solar cells and PV modules must be constantly reduced. The capillary suspension phenomenon (Koos and Willenbacher, Science 331, 897 2011) provides a unique opportunity to design printable pastes and adhesives with high electrical conductivity at low silver consumption. The addition of a second immiscible liquid to a suspension of particles leads to the self-assembly of a strong particle network controlled by capillary forces in such ternary solid/fluid/fluid systems. This results in a drastic change of texture and flow behavior, but also reduces the percolation threshold leading to a high electrical conductivity at low volumetric particle loading in composites including conductive fillers such as silver particles. Pastes for the metallization of temperature-sensitive Perovskite solar cells are sintered at low temperature (< 150°C) and include polymeric additives to provide cohesion of printed finger lines and sufficient adhesion to the transparent conductive oxide (TCO) surface layer. The required polymer content can be reduced and the surface properties of the conductive particles in the contact areas can be designed in such a way that high electrical conductivity and low contact resistance are achieved.
The TECC wire concept uses round copper wires for cell interconnection. These wires are coated with a thermoplastic polymer filled with conductive particles. The polymer ensures good mechanical adhesion to the cell surface and the conductive particles enable low contact resistance. Good interconnection at gentle processing conditions in terms of pressure and temperature has been achieved using thermoplastics with low silver content. Thermoplastic busbars (patent pending) is a recently developed concept further simplifying cell interconnection and reducing resource usage. Electrically conductive, thermoplastic materials melting at low temperature are applied in the metallization process and untreated copper wires are applied in a fast, low temperature stringing process. The capillary suspension concept has been utilized first to design printable, electrically conductive materials including silver particles but the transfer of the concept to composites including other conductive particles such as copper and silver coated copper or glass particles is straight forward.

Pioneering Perovskite Scalability: Advancing Roll-to-Roll Slot Die Coating for Stable and Efficient Flexible Solar Cells
4:30 PM
Anuja Vijayan
The rapid advancement of perovskite solar cells (PSCs) over the past decade has positioned them as one of the most promising photovoltaic technologies in the future.1-2 Their unique properties, including high power conversion efficiencies (PCE), tunable optical properties and low-temperature processability, have opened up new avenues for lightweight, flexible and cost- effective solutions for solar energy capture. 3 Achieving this requires a scalable manufacturing process that ensures device efficiency, operational stability, and environmental sustainability.4 At TNO Solliance, we are developing roll-to-roll compatible processes, such as slot die coating using green solvents and ambient processing conditions, to enable low-cost, high-throughput manufacturing.
To address the associated challenges with scalability, we conducted roll-to-roll (R2R) coating experiments on 30 cm wide flexible substrates at a web speed of 3 m/min, focusing on optimizing drying conditions to enhance efficiency. We developed both opaque and semi- transparent flexible p-i-n perovskite devices, achieving power conversion efficiencies (PCEs) of up to 13% using roll-to-roll (R2R) compatible fabrication methods on polymer based substrates. Thermal stress test (85 °C) confirmed initial stability after 1000 hours of continuous exposure. Additionally, we have explored different hole transport layers (HTL) tailored for R2R processing using non-toxic solvents and also investigated how variations in parameters impact performance, stability and reproducibility.
Our approaches are also utilized in flexible metal foils, which offer several advantages, such as mechanical flexibility, lightweight design, cost-effectiveness, and durability. Devices processed via sheet-to-sheet (S2S) level on 15 × 15 cm2 flexible metal substrates achieved efficiencies of up to ~15% with reproducibility. Preliminary results from these substrates processed using R2R method further confirm their strong scalability potential. Additionally, S2S processed metal
foils using R2R compatible solvents deposited under ambient conditions showed efficiencies exceeding 15% alongside excellent stability. Long-term stability tests on these substrates, where non-encapsulated foils exhibited thermal stability for over 3000 hours at 85°C and 100°C. Encapsulated devices withstand damp heat test(85°C/85% RH) and light-soaking test with additional applied heat (55°C), maintaining both visual and performance stability for over 3000 hours, demonstrating robust, non-degrading perovskite architecture.
To further enhance the scalability and product adaptability our approach supports mass customization through modular solar cell semi-fabricates. Using a combination of R2R techniques and automated pick and place systems, individual cells can be tailored and assembled flexibily either at the production site or final installation point. This enables on- demand design for various applications from infrastructure integration to consumer electronics. Our recent R2R development work has demonstrated promising stability and performance metrics in various configurations. By systematically tuning the coating parameters and
exploring a range of stack designs, we have optimized uniformity and device reproducibility, enabling the large-scale, commercially viable production of perovskite solar cells.

Scott Graybeal
US power consumption is surging, spurred by everything from the proliferation of artificial intelligence to broad electrification efforts.
Solar is an important part of the power supply solution. In 2024, the US brought more solar capacity online than any other single power source in more than two decades. However, meeting increasing power demand while remaining responsive to economic realities requires more powerful solar products, not just more solar modules.
In other words, adding more modules alone won’t solve our energy challenges, as installation costs, volatile interest rates, inflation, and significant land-use constraints are squeezing project economics.
High energy density solar that maximizes the energy output from each module and the overall system footprint.
Deploying high density solar products can enhance the output of existing legacy systems or be paired with emerging module technologies, offering a pathway to develop more cost-effective solar power that is potentially more insulated from international turmoil and supports domestic job creation.
This presentation will cover:
The key economic and logistical drivers challenging conventional solar deployment
How high energy density solar directly addresses cost, land use, and efficiency limitations

A Paradigm Shift in Roll-to-Roll Spatial Atomic Layer Deposition for Perovskite Solar Cell Manufacture
2:05 PM
Hindrik de Vries
Nowadays, Atomic Layer Deposition (ALD) is an key enabling technology in the semi-conductor manufacturing a.o. because of the atomic scale thickness control and excellent conformality in 3D structures. For large area deposition, particularly in roll-to-roll (R2R) processing, such a temporal ALD reactor is highly incompatible due to the fact that the process is operating at low pressure and exposure of precursor and co-reactant is done sequentially in time. Spatial ALD (s-ALD), however, enables parallel exposure of precursor and co-reactant operating at atmospheric pressure which makes it seamlessly compatible with R2R processing. The paradigm in R2R s-ALD consists of a rotating deposition head with the web transported floating on the process gas in counter direction along the perimeter of the deposition head. We propose a paradigm shift in R2R s-ALD. We have developed a robust R2R s-ALD solution which can operate at 100 times higher web speed. Our R&D tool can be utilized for the development of various functional inter-layers in PSCs. To boost the efficiency of PSCs high quality thin films are prerequisite and our R2R s-ALD tool can offer the highest film quality at flexible (0.05-5 m/s) deposition speeds. Several examples of functional inter-layers in PSCs will be showcased from passivation, charge transport and high performance moisture barrier layers. ᐧ

SAW-Based Aerosol Printing for the Future of Electronics
Mehrzad Roudini
Surface acoustic wave (SAW) aerosol generation is redefining droplet-based additive manufacturing with its solid-state, microchip approach. Recent advances have significantly enhanced SAW aerosol generators, enabling high-performance atomization at very low power levels. These compact devices have no moving parts and no nozzles, yet can reliably produce micron- and submicron-scale aerosols with tunable droplet sizes. Compared to traditional ultrasonic or mechanical atomizers, SAW-driven systems offer markedly lower power consumption and greater integrability, all while maintaining precise control over droplet formation. This talk will highlight how such recent developments – from power- efficient acoustic drive schemes to refined chip designs – are paving the way for battery-powered, portable aerosol printheads without sacrificing performance.
We present the design and fabrication of a SAW-based aerosol printhead chip integrated with microfluidics for versatile ink delivery. The SAW chips are fabricated on piezoelectric substrates using standard photolithography for interdigital transducers, combined with a dry-film photoresist lamination process to create on-chip microfluidic channels that feed liquid into the acoustic interaction zone. This wafer-level integration yields a robust, mass-producible device: the fluid is delivered via an embedded microchannel directly to the SAW active region, where it is immediately atomized. A compact, bi-axially mountable chip holder has been developed to interface these SAW chips with existing aerosol printing systems, allowing the device to be oriented as needed while ensuring stable fluid and electrical connections. We have tested a broad range of inks and fluids – from aqueous and organic solutions to highly viscous nanoparticle inks and even biological suspensions – confirming the device’s wide compatibility and clog-free operation.
Experimental results demonstrate finely tunable droplet generation through control of the SAW parameters. By adjusting the SAW wavelength (via transducer geometry), input RF power, and liquid flow rate, we achieve precise control over aerosol droplet size distributions. For example, higher-frequency (shorter wavelength) SAW chips consistently produce smaller droplets at a given flow rate and power, while reducing the liquid flow yields a shift toward smaller droplet diameters. The droplet size can be modulated from the sub-micrometer scale up to tens of micrometers on demand, simply by tuning these
operating conditions. Such tunability, combined with the device’s energy-efficient operation and rapid on/off response, underscores the promise of SAW-based aerosol generators in additive manufacturing. In particular, this technology enables a new class of aerosol printing heads that are compact, power-efficient, and capable of depositing fine features with controlled droplet sizes. These advancements illustrate how SAW-driven aerosol generation can contribute to more efficient printed electronics and high-precision, multi-material additive manufacturing, aligning with the future needs of electronics fabrication and sustainable, energy-efficient printing.

Enabling Durable Perovskite Tandems with Scalable Architecture and Manufacturing Methods
Adam Lorenz
CubicPV is enabling the next leap in solar module design, increasing efficiency to extend the era of LCOE reduction for solar energy with tandem module technology. Perovskite technology has shown tremendous potential over the past decade with tandem performance approaching 35%, but not yet made a commercial impact due to lack of bankable demonstrations combining the trifecta of efficiency, durability and scalability.
This presentation will explain Cubic’s approach to decouple the perovskite and silicon to maximize each component for performance, durability, and cost with as few design constraints as possible. The resulting architecture is simpler to manufacture and will ultimately deliver better field performance than other approaches. We use accelerated aging tests that give developers the assurances they need to deploy new technologies. Beyond just passing the IEC packaging tests, we conduct light + heat testing under very aggressive conditions with 1-sun light soaking including UV at multiple temperatures up to 105°C. Custom hardware for high-throughput simultaneous testing of 1000’s of channels will be described and is being shared with our research partners to accelerate development, with the ability to measure device sizes ranging from lab pixels with 0.1cm2 active area up to Cubic’s serial modules with >1000 cm2 aperture area. These accelerated tests are correlated to outdoor performance and are used to predict field degradation rates.
Sample results include NREL-certified efficiency ~22% perovskite top cell for a high-durability device stack with transparent back contact, corresponding to tandem efficiency approaching 30%.

Enabling Durable Perovskite Tandems with Scalable Architecture and Manufacturing Methods

Adam Lorenz
CubicPV is enabling the next leap in solar module design, increasing efficiency to extend the era of LCOE reduction for solar energy with tandem module technology. Perovskite technology has shown tremendous potential over the past decade with tandem performance approaching 35%, but not yet made a commercial impact due to lack of bankable demonstrations combining the trifecta of efficiency, durability and scalability.
This presentation will explain Cubic’s approach to decouple the perovskite and silicon to maximize each component for performance, durability, and cost with as few design constraints as possible. The resulting architecture is simpler to manufacture and will ultimately deliver better field performance than other approaches. We use accelerated aging tests that give developers the assurances they need to deploy new technologies. Beyond just passing the IEC packaging tests, we conduct light + heat testing under very aggressive conditions with 1-sun light soaking including UV at multiple temperatures up to 105°C. Custom hardware for high-throughput simultaneous testing of 1000’s of channels will be described and is being shared with our research partners to accelerate development, with the ability to measure device sizes ranging from lab pixels with 0.1cm2 active area up to Cubic’s serial modules with >1000 cm2 aperture area. These accelerated tests are correlated to outdoor performance and are used to predict field degradation rates.
Sample results include NREL-certified efficiency ~22% perovskite top cell for a high-durability device stack with transparent back contact, corresponding to tandem efficiency approaching 30%. Rigorous light + heat testing at 90°C, 1-sun, Voc conditions have demonstrated stability of L95 >1000 hours.

Fit-To-Purpose batteries for responsible portable electronics.
3:55 PM

This talk presents a rationale for ecodesign portable batteries by re-thinking their life- cycle under an environmentally conscious framework. Through careful device design and advocating for a ‘fit-to-purpose’ approach, the development of these batteries is paired with the application value chain, in such a manner that even the power source end-of-life is redefined according to the use-case scenario. Several examples of these ecodesigned portable power sources will be
presented. Firstly, a paper-based battery commercialized by Fuelium to power portable diagnostic devices. These liquid activated batteries can be fabricated under the same procedures used in the rapid test industry and have shown the ability to power the most relevant features needed in portable medical devices, such as sensors, displays, wireless communications or heating. Then, further battery concepts developed at BCMaterials will be introduced, such as a bio-based battery using laser induced graphene current collectors in a cardboard tape format for smart packaging, as well as different approaches of biodegradable batteries for precision agriculture and environmental monitoring. Developed under this rationale, environmental sustainability has been placed as a core priority to guide the batteries’ conception and materialization, from materials to end-of-life. Hence all materials used as electrodes, electrolytes, or structural components are abundant, non-toxic and renewable; selected to meet the specific end-of-life requirements and endow a safe and ethical manufacturability.

Indium tin oxide is widely used in transparent applications such as heated glass, antennas, touch screens or smart windows, but has limitations when it comes to e.g. brittleness and low resistances. Metal mesh structures offer a cheaper alternative for truly flexible and low resistance applications.A self-assembled crack template approach enables a fast R2R production on a large-scale. The metal mesh foil based on PET or PC shows both high transparency and low optical haze.

Guest-host liquid crystal system for AR/VR/XR applications
4:35 PM

Augmented Reality (AR/XR) devices are a fast-expanding part of the wearable electronic industry that has attracted significant attention in recent years. One aspect that has hindered their growth and penetration into the broader consumer market is the lack of control of ambient lighting that in tandem with the image combiners such as waveguides control the image display contrast in different lighting conditions. Some technologies such as photochromic and twisted nematic LCDs have been attempted to address this issue. However, their optical and environmental performance was not considered acceptable. Guest host liquid crystals are a new class of materials that are now being successfully employed in commercial AR/XR eyewear to address this issue. In addition to enabling the required image contrast in different lighting conditions, the GHLCs have demonstrated the ability to reduce the overall power consumption of the device and as such extend the battery life during operation. This presentation will focus on this technology, its performance, and implementation in select XR devices.
