Zusammenfassung:	A stacked-layered thin film solar cell and a manufacturing method thereof are provided. The stacked-layered thin film solar cell includes a front electrode layer, a stacked-layered light-absorbing structure, and a back electrode layer. The stacked-layered light-absorbing structure has a p-i-n-type layered structure and consists essentially of I-III-VI compounds, wherein the group III elements at least include indium (In) and aluminum (Al). The p-type layer of the stacked-layered light-absorbing structure is near the front electrode layer while the n-type layer is near the back electrode layer. The Al/In concentration ratio in the p-type layer is higher than that in the n-type layer.
