| 摘 要： | Organic–inorganic halide perovskite solar cells(PSCs)have delivered power conversion efficiency(PCE)on par with that of crystalline silicon solar cells,due to the considerable effort on the optimization of perovskite materials and devices1].The three-dimensional(3D)perovskite-based PSCs with the standard n–i–p architecture gave a certified PCE of25.5%2].However,the poor device stability under operating conditions remains an obstacle to commercialization.The 3D hybrid perovskite materials are susceptible to oxygen,UV light,humidity,heat,and electric fields3].To improve device stability,two main strategies are applied:(1)improving the intrinsic stability4];(2)providing sufficient protection.
