%A Dinh Lam Nguyen %J Engineering Research Express %T Modelling and numerical analysis of ZnO/CuO/Cu2O heterojunction solar cell using SCAPS %X In this work, the SCAPS-1D program was utilized to perform simulations of ZnO/CuO/Cu2O thin-film solar cells. Based on the cell structure and device fabrication process, solar cell structureparameters such as the thickness of the CuO layer, ZnO layer, donor density in the ZnO layer wereevaluated in detail. The results indicated that an optimal structure of ZnO/CuO/Cu2O thin-film solarcell could be obtained when the thickness of the ZnO layer, CuO layer, and donor density in the ZnOlayer is 100 nm, 500 nm, 1×1017cm−3, respectively. The optimized solar cell structure ofZnO/CuO/Cu2O shows a potential efficiency of about 12% under the 1 sun air mass 1.5 G spectrumillumination. Besides that, the performance of the cell under individual solar concentrations andoperating temperatures was also investigated %N 2 %P 025033 %V 2 %D 2020 %R 10.1088/2631-8695/ab9716 %L SisLab3974
