Solar cell and method for manufacturing the same

A method for manufacturing a solar cell comprising:

• 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 a second partial area of the passivation layer paste positioned on the emitter region and a third partial area of the passivation layer paste positioned on the back surface field region 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.
