We have proposed a model using the differences in work function and ionization energy to explain the energy level alignment at the interface between Hole-Collecting Monolayers (HCMs) and perovskites in inverted perovskite solar cells. In this study, we selected five representative carbazole-based HCMs and investigated the influence of their energy levels and molecular orientations on solar cell performance. The results predicted that methyl-substituted HCMs would show high performance.
