Abstract

Substitution of Pb2+ ions in lead halide perovskite Cs0.12FA0.88PbI3 (FA is formamidinium cation) was investigated to address the issues of its phase stability and photostability. The incorporation of optimally selected Nd3+, Tb3+ and Er3+ cations into Cs0.12FA0.88Pb0.99M0.02/nI3 films significantly suppressed the light-induced recrystallization and photodegradation, maintaining the morphology, optical properties and phase composition after 9000 h of light exposure, and improved the efficiency and operational stability of perovskite solar cells.
