Abstract

Direct and inverse photoemission spectroscopies are used to determine materials electronic structure and energy level alignment in hybrid organic–inorganic perovskite layers grown on TiO2. The results provide a quantitative basis for the analysis of perovskite-based solar cell performance and choice of an optimal hole-extraction layer.
