High-performance inverted perovskite solar cells using 4-diaminomethylbenzoic as a passivant

Abstract

films are successfully prepared, which result in the elimination of trap states and enhanced performance of the devices. The highest power conversion efficiency (PCE) of 20.58% is achieved in this work. Meanwhile, the devices show enhanced stability and the average PCE values almost remained the same after 168 hours of storage without any encapsulation. The passivation method developed in this work shows a novel strategy toward the fabrication of inverted PSCs with high efficiency and high stability.
