A thin-film solar cell and a method for manufacturing the same are presented, in which the dopant concentration turns low in a sloping way. The solar cell includes a substrate, a first contact region, a photoelectric conversion layer, and a second contact region. The first contact region a photoelectric conversion layer, and a second contact region are disposed on the substrate. At least one of the first contact region and the second contact region contains an N-type dopant, and the concentration of the N-type dopant is decreased gradually in a direction towards the photoelectric conversion layer. Through the thin-film solar cell and the method for manufacturing the same, the conversion efficiency of the solar cell is improved, and the thin-film solar cell and the manufacturing method are capable of being integrated with an existing manufacturing process of a solar cell, thereby simplifying the manufacturing process and reducing the cost.
