SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME

摘要

A solar cell and a method for manufacturing the solar cell are discussed. An embodiment of the method includes forming an emitter region containing impurities of a second conductive type opposite a first conductive type at a back surface of a semiconductor substrate containing impurities of the first conductive type, forming a passivation layer paste 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 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 connected to the emitter region, and forming a second electrode connected to the back surface field region.
