Numerical simulation studies of a fully inorganic Cs2AgBiBr6 perovskite solar device

Optical Materials, 2020
Abstract With perovskite solar cell (PSC) technology on the brink of commercialization, the use of lead and degradable components remain a concern. We have carried out simulation studies to explore a non-toxic and inorganic device utilizing Cs2AgBiBr6 as the active layer and Cu2O as the hole transport layer (HTL).
