About this collection

The newly appointed Journal of Materials Chemistry A and Materials Advances Advisory Board member, Zhiqun Lin (Georgia Institute of Technology, USA), who has recently come to the end of his time as an Associate Editor, has gathered together the journals’ most outstanding recent papers in perovskite-based photovoltaics for this Editor’s Choice collection.

This Editor’s Choice collection highlights recent advances in perovskite solar cells (PSCs) research in 2021. Four research areas are clearly evident: (i) increasing the efficiency and stability of PSCs; (ii) in conjunction with experimental investigation, more frequent implementation of theoretical approaches, including DFT calculation and machine learning, to elucidate the underlying mechanism and/or perform systematic study; (iii) much effort on large-scale PSCs or small solar modules, particularly flexible perovskite solar modules by roll-to-roll fabrication; and (iv) expanding research from single junction solar cells to tandem solar cells and hybrid devices.

To highlight developments in perovskite-based photovoltaics, this online collection summarizes recent experimental papers and reviews published on the topic. We hope you enjoy reading this collection.
