Abstract

Abstract : In article number 1604695, Wallace C.H. Choy and co‐workers propose a novel room‐temperature scheme of pyridine‐promoted formation of perovskite films featuring large grain‐sizes, and high crystallinity, while being free of residues. This new approach enables the fabrication of all room‐temperature, solution‐processed perovskite solar cells (PVSCs) with a record efficiency of 17.10% and 14.19%, with no hysteresis on rigid and flexible substrate respectively.
