Method for solar cell manufacturing

A solar cell and a method for manufacturing the solar cell are discussed. An embodiment of the method includes forming an emitter region (121) containing impurities of a second conductive type opposite a first conductive type at a back surface of a semiconductor substrate (110) containing impurities of the first conductive type, forming a passivation layer paste (150) containing impurities of the first conductive type on the emitter region, selectively performing a thermal process on a first partial area of the passivation layer paste to form a back surface field region (172) containing impurities of the first conductive type at a partial area of the emitter region, forming a plurality of openings in partial areas of the passivation layer paste to form a passivation layer, forming a first electrode (141) connected to the emitter region (121), and forming a second electrode (142) connected to the back surface field region (172).
