Copolymer Mediated Engineering of Halide Perovskites and Associated Devices: Current State and Future

Abstract

The field of halide perovskites has advanced significantly within a decade, as engineering strategies are addressing many of the challenges and as a result improved environmental stability and electro‐optical properties have been achieved. The use of the copolymer additive strategy has received significant attention in recent years as a variety of polymers with significant differences in properties such as water affinity, polarity, elastic modulus, ion conductivity and basis for interaction with perovskite can be selected and combined with halide perovskite. As a result, there has been a rapid increase in publications reporting the effectiveness of the inexpensive and readily available copolymer additives in altering the physicochemical, mechanical, and electro‐optical properties of the halide perovskites‐based high‐performance devices. This article is an effort to provide insight into the current state of copolymer‐mediated engineering of halide perovskites with a perspective on the reported improvements in the properties and performance of the perovskite‐based devices. Critical analysis is done on the potential of the copolymer–perovskite materials toward realizing commercial applications.
