Effect of BCP buffer layer on eliminating charge accumulation for high performance of inverted perovskite solar cells

A power conversion efficiency of 17.9% has been obtained for the device with a critical BCP thickness of 5 nm. While if the BCP layer is too thin or too thick, charge accumulation will emerge and lead to device performance degradation.
