SOLARBATTERIEZELLE UND VERFAHREN ZU DEREN HERSTELLUNG |
摘要 |
<p>A solar battery cell including: a semiconductor substrate; front-surface asperities formed on the principal surface on a light-receiving side of the semiconductor substrate; a semiconductor layer having a conductive type and formed along the front-surface asperities; and an anti-reflection film formed on the light-receiving side of the semiconductor layer, a passivation film is formed on the principal surface on the back-surface side of the semiconductor substrate, and at least one opening is provided in the passivation film. A first back-surface electrode is formed on the passivation film so as to overlap the entire area occupied by the opening and to cover the opening, and a second back-surface electrode is formed on the passivation film so as to overlap the entire area occupied by the first back-surface electrode and to cover the first back-surface electrode.</p> |
