Enhancing moisture tolerance in efficient hybrid 3D/2D perovskite photovoltaics

Abstract

Hybrid 3D/2D perovskites combine the high efficiency of 3D perovskites and the stability of 2D perovskites, and possess longer photoluminescence lifetimes, lower trap-state densities and enhanced moisture tolerance. The hybrid 3D/2D structure is a successful strategy to improve stability without sacrificing conversion efficiency.
