A high-efficient silicon thin-film solar cell is provided to reduce carrier recombination generated by light and to increase efficiency by using a buffer layer inserted into a p-layer and an i-layer. A high-efficient silicon thin-film solar cell is provided with one or more solar cell layers which are laminated thereon. The solar cell layer includes a buffer layer(200) between a p-layer(103) and an i-layer(104). The buffer layer is doped with a p-type. The buffer layer is made of one selected from a carbide, an oxide, a nitride, and a fluoride of Si:H. A lower glass substrate, a lower transparent conductive layer, plural pin semiconductor layer, a transparent conductive layer, and a rear electrode layer are sequentially laminated in the solar cell layer. A transparent electrode layer is formed between the pin semiconductor layers.
