We carried out simulative investigations on a non-toxic, lead-free perovskite solar cell (PSC), where Cs2AgBiBr6, P3HT, ZnO nanorod, and C were utilized as the absorber layer, hole transport layer, electron transport layer, and back contact, respectively. At 600 nm optimum absorber thickness, the de...
