Abstract

Abstract : An ultrathin poly(ethylenimine) ethoxylated (PEIE) layer inserted underneath alters the work function and surface energy of the top SnO2 surface. This PEIE/SnO2 electron transport composite structure demonstrates negligible energy mismatch at the interface leading to high performance perovskite photovoltaic devices.
