Ambient atmospheric temperature processed lead halide perovskites

Abstract

Perovskite, ABX3, materials are usually synthesized in inert atmosphere. Their properties are severely affected by the humidity and temperature of the surroundings which is very far from real-life applications. Hence, in the present work, bulk systems of CH3NH3PbI3 and CsPbI3 processed at ambient temperature and pressure have been investigated for their thermodynamics parameters, structural, optical and electronic features. Simultaneously, an attempt has been made to understand the role of methylammonium ion (CH3NH3 +) in lead halide perovskite. © 2019, Akadémiai Kiadó, Budapest, Hungary.
