Abstract
The importance of interfacial engineering as a new strategy for improving the power conversion efficiencies (PCEs) of planar-hetero junction (PHJ) perovskite solar cells is highlighted in this study. With our optimized interfacial modification, we demonstrated efficient PHJ perovskite solar cells with a high PCE of 12.2% using a sol-gel-processed ZnOECL modified by [ 6,6]-phenyl C-61 butyric acidmethyl ester (PCBM).
