    摘要: The invention discloses a thin film solar cell and the manufacturing method thereof. The thin film solar cell comprises a substrate, a back electrode layer, an absorber layer, a buffer layer, and a transparent electrode layer. The buffer layer is a compound consisted essentially of a metal and at least two elements of Group VIA. The compound has a chemical formula of Mx (VIA1y, VIA2z)w. M represents a singular metal element or an alloy of multiple metal elements, and VIA1 and VIA2 are two different elements of Group VIA. X, y, z and w are non-zero positive numbers. The buffer layer has a band gap gradient between the absorber layer and the transparent electrode layer.
