Abstract
A method for manufacturing a solar cell may include forming an emitter region that forms a p-n junction with a semiconductor substrate of a first conductive type, forming a passivation layer on the semiconductor substrate, forming a dopant layer containing impurities of the first conductive type on the passivation layer, and locally forming a back surface field region at the semiconductor substrate by irradiating laser beams onto the semiconductor substrate to diffuse the impurities into the semiconductor substrate.
