Abstract
Lead halide perovskite semiconductors shows a unique defect tolerance nature that enables high efficiency in photovoltaic power conversion. For enhancing efficiency, photovoltage is the important focus of improvement in terms of energy loss on bandgap energy. Our strategy to enhance voltage output towards theoretical limit levels by compositional engineering of heterojunction interfaces is presented for organic-inorganic hybrid and all-inorganic perovskites.
