dc.description.abstract Tandem solar cells have been researched to enhance the performance of the second generation (II-VI) thin-film solar cells. In this study, we have developed an efficient tandem solar cell model by optimizing the thickness of the (II-VI) layers and by introducing Mg doped ZnO as the window material for the top cell. The tandem solar cell model consists of a top cell, n-MZO/p-CdTe and a bottom cell, n-CdS/p-Cu(In, Ga)Se2 (CIGS). The parameters of the computational model, such as thicknesses of n-CdS, p-CIGS. pCdTe has been varied to improve the efficiency of the tandem solar cell and compared with the previous researched single junction thin-film solar cells. All the numerical experiments were conducted under one sun illumination condition with AM 1.5 G solar spectrum by using the Analysis of Microelectronic and Photonic Structures simulation software (AMPS-1D) and Solar Cell Capacitance Simulator (SCAPS 1-D) software. The observed open circuit voltage was 1.413 V and the efficiency wa sincreased to 28.84% and this is a huge improvement compared to the reported recorded best research cell values of 0.8 V and 24.2% respectively for single junction solar cell. en_US
