Abstract
A solar cell element includes: a transparent body; a MgAglayer (0.001≦x≦0.045) having a thickness (2-13 nm); a ZnO layer having an arithmetical mean (Ra: 20-870 nm); and a transparent conductive layer. A photoelectric conversion layer including n-type and p-type layers further includes n-side and p-side electrodes. The ZnO layer is composed of ZnO columnar crystal grains grown on the MgAglayer, and each ZnO grain has a longitudinal direction along a normal line of the body, has a width increasing from the MgAglayer toward the transparent conductive layer, has a width which appears by cutting each ZnO grain along the normal line, and has a R2/R1 ratio (1.1-1.8). R1 represents the width of one end of the ZnO grain, and the one end is in contact with the surface of the MgAglayer, and R2 represents the width of the other end of the ZnO grain.
