ABSTRACT
Perovskite solar cells (PSCs) have experienced considerable development in the past few years. The stability issue has become a focus of research efforts toward their commercial applications. and interface engineering electron transport materials (ETMs) to build up stable interfaces with perovskites been emerging as powerful strategy enhance PSCs' stability. Herein, cubic zinc metatitanate (ZTO) is identified an excellent ETM treatment dezincification for fabricating PSCs much better overall performances than those fabricated from TiO 2 , popularly used ETM. high mobility ZTO helps minimize hysteresis. Together use CuSCN inorganic hole material further protecting reduced graphene oxide, ZTO‐based exhibit remarkable enhancement stability, retaining 95% initial power conversion efficiency under AM 1.5 G illumination at 85 °C 85% relative humidity air 1000 h open circuit.
