Abstract

Abstract : Organic–inorganic halide perovskite (OIHP) solar cells have garnered great attention in the last decade since they continuously approach the Shockley–Queisser Limit. Compared with conventional organic and inorganic semiconductors, OIHPs possess the high tolerance on defects due to the dominated intrinsically shallow‐level carrier‐trapping centers. However, the existence of defects still causes the ion migration, produces the hysteresis effect, and accelerates the film degradation, eventually suppressing the device efficiency and stability. In this Review Article, we summarize recent impressive advance on passivating OIHP defects and discuss the future horizon of exploiting high‐efficiency and long‐stability OIHP solar cells in terms of defect managements. Abstract : Recent impressive advance on passivating the defects of organic‐inorganic halide perovskite solar cells has been summarized.
