Abstract
A photoelectric converting device is provided with enhanced photoelectric conversion efficiency by optimizing a combination of materials used for top and bottom cells. The photoelectric converting device of the present invention is provided with first and second pn junctions. The first pn junction is formed in a semiconductor substantially represented by (Al1−yGay)1−xInxP, and the second pn junction is formed in a semiconductor substantially represented by Ga1−zInzAs.
