We studied the impact of the front-window layer on Cu(In,Ga)Se2 (CIGS) solar cells. A bi-layer structure of ZnO:Al/ZnO was used as a standard front-window layer, and a replacement of ZnO by Zn1-xMgxO was analyzed. A numerical simulation was performed to understand the device characterization results. The results clearly indicate that any variation on the front-window layer and deposition condition impacts the underlying CdS/CIGS junction. Therefore, it is important to carefully choose the component of the front-window layer and sputtering parameters to protect the junction formation. With careful frontwindow layer design and modeling, an optimized device performance with a Zn1-xMgxO layer has been achieved.
