SOLAR CELL AND METHOD FOR MANUFACTURING THE SAME |
摘要 |
<p>A solar cell (10) including a passivation film having a high effect for both a p region and an n region on a surface of a silicon substrate of the solar cell is provided. In the solar cell, a first passivation film made of a silicon nitride film is formed on a surface opposite to a light-receiving surface of the silicon substrate, and the first passivation film has a refractive index of not less than 2.6. Preferably, in the solar cell, a second passivation film including a silicon oxide film and/or an aluminum oxide film is formed between the silicon substrate and the first passivation film. Preferably, the solar cell is a back surface junction solar cell having a pn junction formed on the surface opposite to the light-receiving surface of the silicon substrate.</p> |
