Aging of perovskite solar cells: a mini review
Introduction With the power-conversion efficiencies (PCEs) of metal halide perovskite solar cells (PSCs) reaching 25.8% [1], long-term stability has become the next goal for commercialization. Recent studies have reported T 80 lifetimes (time at which the PCE drops to 80% of its initial value) of more than a thousand hours under continuous …
