摘要: The present invention discloses a thin-film solar cell and a method for forming the same. The thin-film solar cell includes a substrate and a semiconductor layer containing a P-type crystalline silicon layer over the substrate, a first I-type crystalline silicon layer on the P-type crystalline silicon layer, a first N-type crystalline silicon layer on the first I-type crystalline silicon layer, a second I-type crystalline silicon layer on the first N-type crystalline silicon layer and a second N-type crystalline silicon layer on the second I-type crystalline silicon layer. Wherein, the semiconductor layer is formed with additional I-type and N-type crystalline silicon layers, thereby enhancing the photoelectric conversion efficiency of the thin-film solar cell.
