<p>PROBLEM TO BE SOLVED: To provide a solar cell capable of maximizing efficiency.SOLUTION: A solar cell includes: a semiconductor substrate; a conductive region formed in the semiconductor substrate and having a conductivity type identical to or different from that of the semiconductor substrate; a passivation film formed on the semiconductor substrate so as to cover the conductive region; and an electrode electrically connected to at least one of the semiconductor substrate and the conductive region. The passivation film includes: a first layer formed on the conductive region and including a silicon oxide; a second layer formed on the first layer and including an oxide having a negative charge; and a third layer formed on the second layer and having an index of refraction different from that of the second layer.</p> |
