Semiconductor film, method for manufacturing the semiconductor film, solar cell using the semiconductor film and method for manufacturing the solar cell |
摘要 |
A semiconductor film has a composition in which a Group Ia element and a Group Vb element are added to a compound semiconductor with a chalcopyrite structure containing a Group Ib element, a Group IIIb element and a Group VIb element. This allows the provision of a semiconductor film whose carrier density can be controlled effectively. A solar cell of the present invention includes: a substrate and the semiconductor film of the present invention that is provided as a light-absorption layer on the substrate. With this configuration, a light-absorption layer whose carrier density can be controlled effectively can be provided, so that a solar cell having a high energy conversion efficiency can be provided.
