文摘

The structure and performance parameters of a dual junction CGS/CIGS solar cell including a CdS antireflection top layer are studied and optimized using Silvaco ATLAS software to obtain maximum possible value of efficiency. To gain a optimized design, the affects of CIGS bottom cell band gap and m>nm>-type doping concentration on the efficiency of the cell were examined and the optimum values of these parameters were obtained. In continue, the maximum J_SC which is occurs when the current values of the two sub-cells are matched was obtained by varying the thickness of CdS layer, where an optimum efficiency of 43.05% is achieved.
