PROBLEM TO BE SOLVED: To decrease an optical reflective loss on an interface with a transparent oxide electrode p-type semiconductor layer by a method wherein there are formed a lights scattered layer having an uneven surface shape; a transparent oxide electrode; an optical electricity generator layer composed of amorphous silicon; and a metal electrode by sequential lamination on a translucent insulation substrate. SOLUTION: A lights scattered layer 2 is provided on a translucent insulation substrate 1, and a transparent oxide electrode 3 is provided on this lights scattered layer 2, and further a p-type semiconductor layer 4, an intrinsic semiconductor layer 5, and an n-type semiconductor layer 6 are sequentially provided in part on the transparent oxide electrode 3 and lights scattered layer 2, and further a metal electrode 7 is provided on the n-type semiconductor layer 6. This lights scattered layer 2 functions as leading incident sunlights to the transparent oxide electrode 3, the p-type semiconductor layer 4, the intrinsic semiconductor layer 5, and the n-type semiconductor layer 6. Furthermore, as an interface shape between the transparent oxide electrode 3 and the p-type semiconductor layer 4 is uneven at this solar battery element, the lights scattered layer 2 collectively functions as reducing a reflective loss on this interface due to scattering effects of the incident sunlight generated thereby. |
