SOLAR CELL

摘要

PURPOSE: A solar cell is provided to increase efficiency of solar cell by having a rear surface electric field area and a fixed charge area together. CONSTITUTION: A solar cell includes a semiconductor substrate, a rear surface passivation film(131), a rear surface electrode(140), a barrier film(132). The rear surface passivation film is positioned in the rear surface of the semiconductor substrate. The rear surface electrode is positioned in the one side of the rear surface passivation film and is formed from a conductive paste which includes conductive power and metal glass. The barrier film is positioned between the rear surface passivation film and the rear surface electrode and has a non-through property about metal glass.
