Advancing perovskite photovoltaics for space: critical stability testing guidelines

Low-Earth orbit, the primary operational domain for the international space station and commercial satellites, presents a severe thermodynamic environment for spacecraft. Current testing methodologies, such as thermal cycling and damp-heat assessments, are inadequately aligned with the characteristics of perovskites. The commentary suggests a tiered thermal stress testing framework to enhance existing standards and support a robust and standardized framework for certification.
