Abstract
A solar cell is constructed using a heterojunction formed by layering an n-type compound semiconductor followed by a p-type compound semiconductor on an insulator layer containing titanium oxide which has been formed on one side of a glass plate. The insulator layer can improve the photoelectric conversion efficiency of the solar cell by lowering the sheet resistance of the n-type semiconductor film which is used as the window material of the solar cell. In addition, light transmittance is improved.
