What does it take to scale perovskite solar cells from the lab to 20x20 cm² modules with industrial methods?
IPVF showcases its track record in scaling up perovskite solar technology, progressing from small lab-scale cells to mini-modules with sizes of 10x10, 15x15, and now 20x20 cm². Throughout this scaling process, they have consistently increased power conversion efficiencies, with recent results approaching 17% on these larger areas. This demonstrates a systematic approach to overcoming the challenges associated with maintaining high performance on larger substrates.
The core of their device development is a p-i-n architecture, which is well-suited for industrial "sheet-to-sheet" processing. Their R&D focuses heavily on understanding and optimizing the industrial methodologies for depositing each layer in the stack. This includes developing advanced crystallization techniques not only for the perovskite absorber layer but also for the p-type and n-type charge transport layers, which are crucial for efficient charge extraction.
To support this development, IPVF relies on a well-equipped technological platform for comprehensive device monitoring. They utilize a suite of tools for both outdoor and indoor characterization, allowing them to precisely measure electrical parameters and track performance over time. This rigorous characterization of efficiency, lifetime, and stability is essential for generating the reliable data needed to prove the technology's bankability to industrial partners.
In this short video, you can learn:
* The progression of scaling perovskite modules up to 20x20 cm² while achieving efficiencies near 17%.
* The focus on industrializing the p-i-n device architecture, including crystallization methods for all layers.
* The importance of a robust characterization platform for monitoring lifetime and stability to ensure bankability.
📋 **Clip Abstract** IPVF outlines their R&D strategy for scaling perovskite photovoltaics, detailing their progress in achieving nearly 17% efficiency on 20x20 cm² modules. Their work centers on industrializing the p-i-n device architecture and is supported by a comprehensive characterization platform to validate performance and stability.

How do you equip a pilot line to manufacture 30x60 cm² perovskite solar modules?
How do you equip a pilot line to manufacture 30x60 cm² perovskite solar modules?
IPVF is building a versatile pilot line in a 500 m² cleanroom to produce large-area (30x60 cm²) perovskite active layers. The line is designed with separated, modular equipment, allowing for process flexibility and the ability to choose different deposition methods for specific layers in the device stack. This approach facilitates R&D and process optimization while mimicking an industrial workflow.
The line incorporates a comprehensive set of industrial-grade tools. Key deposition equipment includes a thermal ALD reactor, vertical sputtering machines, and a large-area thermal evaporator. The evaporator is specifically configured for depositing the electron transport layer (C60) and contact layers like lithium fluoride, which are critical for high-performance p-i-n device architectures.
To enable solution-based processing, which is a key advantage of perovskite technology, the pilot line will feature a slot-die coater. This tool is essential for depositing the perovskite active layer and other solution-processed layers with high uniformity over large areas. The line is also equipped with large-area solar simulators for immediate characterization and quality control of the finished modules.
In this short video, you can learn:
* The specific equipment chosen for a perovskite PV pilot line, including ALD, sputtering, evaporation, and slot-die coating.
* The target substrate size (30x60 cm²) and the versatile, modular layout of the production line.
* Key materials deposited by each tool, such as C60 and LiF via evaporation, for building a complete p-i-n device stack.
📋 **Clip Abstract** IPVF details the specific industrial-grade equipment being installed in their new 500 m² pilot line for manufacturing 30x60 cm² perovskite modules. The versatile setup includes ALD, sputtering, evaporation, and slot-die coating tools to enable flexible R&D and process scale-up.

Can you watch a perovskite solar cell degrade in real-time to understand how to make it last longer?
Can you watch a perovskite solar cell degrade in real-time to understand how to make it last longer?
A critical challenge for perovskite photovoltaics is long-term stability, which IPVF addresses through comprehensive backend optimization. This involves a multi-pronged approach to encapsulation, experimenting with different additives on the electrical contacts and testing various polymers for both protecting the layers and creating a hermetic seal. The goal is to create a robust package that prevents environmental degradation and increases module lifetime.
The effectiveness of these strategies is validated through rigorous accelerated aging tests, specifically damp heat (DH) testing. IPVF demonstrates modules that pass DH1000 and DH2000 tests with less than 20% performance degradation, a key milestone for bankability. This shows that their encapsulation and material optimization strategies are successfully mitigating major degradation pathways.
IPVF employs advanced in-situ characterization to gain deeper insights into degradation mechanisms. By periodically removing samples from the climate chamber during aging and performing luminescence measurements, they can track changes within the device stack. This powerful technique allows them to observe phenomena like bandgap shifts in real-time, which they correlate with material changes such as phase segregation, providing crucial feedback for developing more stable perovskite formulations.
In this short video, you can learn:
* Strategies for backend optimization and encapsulation, including contact additives and sealing polymers.
* Successful results from 1000-hour and 2000-hour damp heat stability tests.
* An advanced characterization technique using luminescence to analyze degradation mechanisms like phase segregation during aging.
📋 **Clip Abstract** IPVF presents its approach to improving perovskite module stability through advanced encapsulation, achieving success in 2000-hour damp heat tests. They utilize in-situ luminescence analysis during aging to directly observe degradation mechanisms like phase segregation, enabling targeted material improvements.
