PURPOSE:To improve the rflection preventive effect and the characteristic of a solar cell by properly selecting the height of a crest, the depth of a trough and surface ruggedness of a substrate, and by depositing an amorphous silicon thin film on the substrate. CONSTITUTION:An element for generating photoelectromotive force is formed by depositing an amorphous silicon thin film containing a hydrogen or fluorine atom on the substrate. The substrate used at this time has such surface ruggedness that the height of its crest and the depth of its trough locate in a range of 0.02-0.5mum from the center line thereof and the sum of the height and depth is not greater than 0.8mum. |
