Phase Transition in Halide Double Perovskites for Solar‐To‐Chemical Energy Conversion

Advanced Energy Materials, EarlyView.
Disorder‐to‐order phase transition in double perovskite Cs2AgBiBr6 eliminates self‐trapped excitons and antisite defects and promotes charge separation, with over sixfold photoactivity enhancement in photocatalytic C−H bond activation. Abstract Halide double perovskites have recently garnered significant interest in solar energy conversion applications

Unveiling the Impact of C60–O2 Interaction on the Performance and Characterization of Perovskite Solar Cells

Advanced Energy Materials, EarlyView.
Air exposure of the C60 electron‐transport layer (ETL) in p‐i‐n perovskite solar cells causes rapid O2 intercalation, forming deep trap states and altering charge carrier balance at the perovskite/ETL interface, thereby increasing non‐radiative recombination.
