摘要： The present disclosure relates to novel perovskite solar cells, and the method of making and using the novel perovskite solar cells. More specifically, a triple cation perovskite solar cell device containing a multifunctional capping layer (MCL) of R1NH3+ and/or a thin layer of two-dimensional (2D) material of (R1NH3+)2(A+)n−1(M2+)n(X−)3n+1 on top of the commonly used ABX3 perovskite, with enhanced power conversion efficiency of 22.06% (from 19.94%) with long-term stability over 1000 hours under continuous illumination has been developed.
