摘要： In a solar cell, a crystal defect layer by ion implantation or an amorphous layer by ion implantation is formed between p type diffusion layers provided in an island-like manner at a side opposite to a light receiving surface of a low concentration p type semiconductor single crystalline substrate. The element of the ion implantation may be at least one selected from the group consisting of hydrogen, silicon, germanium, fluorine, oxygen and carbon. The constituent substance of the semiconductor substrate, such as Si is preferably used for the ion implantation. In such a solar cell structure having the crystal defect or amorphous layer, relatively long wavelength light that could not effectively be utilized in the prior art solar cell may be utilized so that the photoelectric conversion efficiency may be improved.
