WebHowever, additives such as MA, caesium, and bromine widen its bandgap and reduce the thermal stability. We stabilized the α-FAPbI3 phase by doping with methylenediammonium dichloride (MDACl2) and achieved a certified short-circuit current density of between 26.1 and 26.7 milliamperes per square centimeter.

Web15 mei 2024 · SnO 2 is a promising alternative for TiO 2 electron transporting layer (ETL), owing to the high charge mobility and chemical stability. Defects accumulating at interfaces and grain boundaries are detrimental to the performance of perovskite solar cells (PSCs). Herein, a ligand-biphenyl-3,3′,5,5′-tetracarboxylic acid butyl amine (BPTC-BN) with four … WebMin et al. show that doping of the α-FAPbI3 phase with methylenediammonium dichloride enabled power conversion efficiencies of 23.7%, which were maintained after 600 hours of operation. Unencapsulated devices had high thermal stability and retained >90% efficiency even after annealing for 20 hours at 150°C in air.
