Abstract

A photovoltaic device includes a first electrode; a second electrode spaced apart from the first electrode; a perovskite layer between the first and second electrodes, the perovskite layer including a semiconducting halide perovskite photoactive material; and a vacuum-level modulating layer formed on a surface of the perovskite layer. The vacuum-level modulating layer provides crystal defect passivation of the surface of the perovskite layer, and the vacuum-level modulating layer further modulates surface energetics of the surface of the perovskite layer to mitigate formation of a potential well so as to avoid charge accumulation therein.
