Enhancing J_sc of solar cells consisting of mixed metal perovskite, MASn_0.5Pb_0.5I₃ is reported. However, the open-circuit voltage is much lower than conventional lead perovskite solar cells
This presentation is for the improvement of the open-circuit voltage by the charge separation interface control of Sn-Pb binary perovskite solar cells.
