Abstract
A solar cell element having a transparent substrate body, a NaAg, layer, a ZnO layer, a transparent conductive layer, and a photoelectric conversion layer including an n-type semiconductor layer and a p-type semiconductor layer. The transparent substrate body, the NaAglayer, the ZnO layer, the transparent conductive layer, and the photoelectric conversion layer are stacked in this order, x represents a value of not less than 0.001 and not more than 0.02, the NaAglayer has a thickness of 2-15.2 nanometers, and the ZnO layer has an arithmetical mean roughness of not less than 20-750 nanometers. The ZnO layer is composed of a plurality of ZnO columnar crystal grain, each ZnO columnar crystal grain has a longitudinal direction along a normal line direction of the transparent substrate body, and each ZnO columnar crystal grain has a R2/R1 ratio of 1.1-1.6.
