Optimal Design and Simulation of High-Performance Organic-Metal Halide Perovskite Solar Cells

The organic-metal halide perovskite solar cells have recently shown the high power conversion efficiency (PCE) exceeding 20%. A better understanding of the relationships between material parameters, device architectures, and performance is still required for the continued development of the perovskite solar cells. Three types of architectures are simulated with the program 1-D device simulation program for the analysis of microelectronic and photonic structure. The hole transport material-free MAPbI
₃
solar cells attain the simulated PCE of 24.1%. A maximum PCE of 26.60% and a maximum V
_OC
(open-circuit voltage) of 1.83 V for FTO/ZnO/MAPbX

(X = I and Br)/CuSCN/Au-based solar cells are predicted, respectively. The FTO/ZnO/MAPbI

/MAPbBr

/CuSCN/Au-based solar cells first designed possesses a characteristic of tunable PCE and V
_OC
by changing the thicknesses of MAPbI

and MAPbBr

, and the PCE of 27.50% (J

, V
