<p>PROBLEM TO BE SOLVED: To provide a solar battery for applying hydrogen sufficiently inside a silicon substrate. SOLUTION: While one main face of a silicon substrate having a pn-junction is roughened into a rough face state, an anti-reflective film made of silicon nitride is formed on the one-main-face side of the silicon substrate, and each electrode is formed on both main faces of the silicon substrate in the solar battery. A crystal defect is formed in the vicinity of the surface of the one-main- face side of the silicon substrate.</p> |
