Solar cell

摘要

Disclosed is a solar cell that comprises a substrate made of a semiconductor material, a first amorphous semiconductor layer placed on one region of the substrate and being of one conductivity type, a second amorphous semiconductor layer placed on another region of the substrate and being of another conductivity type, a substantially intrinsic i-type amorphous semiconductor layer provided above the first amorphous semiconductor layer, a third amorphous semiconductor layer provided on the i-type amorphous semiconductor layer and being of the other conductivity type, a first crystalline semiconductor layer placed between the first amorphous semiconductor layer and the i-type amorphous semiconductor layer and being of the one conductivity type, and a second crystalline semiconductor layer placed between the first crystalline semiconductor layer and the i-type amorphous semiconductor layer and being of the other conductivity type.
