Boosting photodetection performance of Cs2AgBiBr6 through A-site Rb substitution and interfacial engineering

Journal of Colloid and Interface Science, 2023
Bismuth-based double perovskite Cs2AgBiBr6 shows promise as a photodetection material. However, its detection performance and application are limited by high-exciton binding energy and poor carrier mobility. In this study, we address these limitations by delicately designing a solution-based method for incorporating A-site Rubidium (Rb) substitution ...

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).
