Abstract
The Photovoltaic Accelerator for Commercializing Technologies (PACT) center is a collaboration between Sandia National Laboratories and The National Laboratory of the Rockies (NLR), formerly known as NREL, initiated in July 2021 to accelerate the commercialization of novel photovoltaic (PV) module technologies, such as metal halide perovskite (MHP). As of December 2025, PACT has received 833 MHP modules, comprised of single- and multi-junction solar cells, for indoor and outdoor testing. These samples originate from nine companies and eight research labs and universities worldwide, with module sizes ranging from 20 cm² to nearly 8,000 cm². PACT supports the commercialization of new technologies by offering free indoor and outdoor module testing services for companies and research institutes. We anonymize performance data and share general trends to help companies and funding agencies evaluate state-of-the-art performance and reliability, tracking trends in module efficiency and durability, measured as time to reach 80% of peak outdoor efficiency (T80). Indoor testing focuses on developing and validating accelerated tests to screen for early failures in outdoor exposure and addressing challenges in preconditioning test protocols for this technology. Despite significant progress in improving efficiency and durability, barriers remain for widespread MHP module commercialization. This talk will summarize these barriers, including performance and reliability, quality and consistency, testability, system integration, balance of systems, and potential material toxicity. We will provide an overview of PACT's findings from testing hundreds of modules globally, present anonymized data compilations from outdoor testing results, review the state-of-the-art from the modules tested, and discuss additional challenges that are crucial for the market success of this technology.
