摘要

Organometal halide perovskite has drawn much attention due to their high light-absorption coefficient,outstanding carrier mobility,and long-range charge-transport lengths.The most remarkable progress made by this type of perovskite materials is in the field of photovoltaics [1-4].The power conversion efficiency (PCE) of perovskite solar cells (PSCs) has exceeded 25％ since they were first used as the active layer in solar cells in 2009 [5],which is comparable to single-crystal silicon solar cells and approaching the Shockley-Queisser efficiency limit of single-junction cells [6].
