Most state-of-art CIGS based solar cells employs CdS as buffer layer. However, due to its toxic nature, there is need for searching possible alternatives. In this work, the performance of the CIGS solar cells was simulated using SCAPS-1D software. Photovoltaic parameters of CIGS solar cells using different buffer layer materials; CdS, ZnS, ZnO, ZnSe and InS were simulated. The optimized thickness of buffer and absorber layers was found to be 0.02µm and 0.75µm respectively for the selected ZnO buffer layer. Also, for the optimized cell, the Voc, Jsc, FF, and efficiency were found to be 0.8842V, 34.3739mA/cm2, 80.63% and 24.51% respectively. Finally it was found that ZnO can be a good material that can substitute the toxic CdS element for the production of solar cell and promise high efficiency.
