Damp heat–stable perovskite solar cells with tailored-dimensionality 2D/3D heterojunctions

Damp heat–stable perovskite solar cells with tailored-dimensionality 2D/3D heterojunctions If perovskite solar cells (PSCs) with high power conversion efficiencies (PCEs) are to be commercialized, they must achieve long-term stability, which is usually assessed with accelerated degradation tests. One of the persistent obstacles for PSCs has been successfully passing the damp-heat test (85°C and 85% relative humidity), which is the standard for verifying the stability of commercial photovoltaic ...
