Abstract

Efficient mesoscopic CH₃NH₃PbI₂Br perovskite solar cells have been prepared based on the TiO₂/Al₂O₃/carbon architecture. An appreciable power conversion efficiency of 11.03% was achieved under AM 1.5G illumination. This system combines the superior stability of MAPbI₂Br and no requirement of a hole conductor layer.
