    Abstract: A solar cell and a method for manufacturing the same are discussed. The method for manufacturing the solar cell includes forming an amorphous silicon layer on a back surface of a crystalline semiconductor substrate containing impurities of a first conductive type, performing a first diffusion process for diffusing impurities of a second conductive type opposite the first conductive type into a portion of the amorphous silicon layer to form an emitter region, and performing a second diffusion process for diffusing impurities of the first conductive type into a remaining portion except the portion of the amorphous silicon layer having the impurities of the second conductive type to form a back surface field region. When at least one of the first diffusion process and the second diffusion process is performed, the amorphous silicon layer is crystallized to form a silicon layer.
