Effects of Adding Alkali Metals and Organic Cations to Cu-Based Perovskite Solar Cells

First-principles electronic band calculations were used to investigate the effects of alkali metals and organic cations added to Cu-based perovskite solar cells. The copper d-orbital band was slightly above the valence-band maximum and functioned as an acceptor level for carrier generation. Excitati...
