    • 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.
    • 目的:提供太阳能电池,通过将背面电场区域和固定电荷区域组合在一起来提高太阳能电池的效率。 构成:太阳能电池包括半导体衬底,后表面钝化膜(131),后表面电极(140),阻挡膜(132)。 后表面钝化膜位于半导体衬底的后表面。 后表面电极位于背面钝化膜的一侧,并且由包括导电电力和金属玻璃的导电膏形成。 阻挡膜位于后表面钝化膜和后表面电极之间,并且具有关于金属玻璃的非贯通性。
