Recent advances in perovskite solar cells: efficiency, stability and lead-free perovskite

Abstract

In this review, we first highlighted recent progress in high-performance perovskite solar cells (PVSCs) with a discussion of the fabrication methods and PVSCs-based tandem solar cells. Furthermore, the stability issue of PVSCs and strategies to improve material and device stability have been discussed, and finally, a summary of the recent progress in lead-free perovskites has been presented.
