Perovskite solar cell was prepared using three-dimensional perovskite compounds, FA_xMA_1-xPb (I_xBr_1-x)₃, having formamidinium and methylammonium as cations, aiming at application to artificial leaves. The effect of the ratio x on the cell performances were evaluated. The cell using FA_0.75MA_0.25Pb(I_0.75Br_0.25)₃ showed the best power generation characteristics and recorded a conversion efficiency of 16.3%. Artificial leaves were prepared by coating with a platinum catalyst.
