PROBLEM TO BE SOLVED: To increase the photoelectric transfer efficiency of a photoelectric transfer type power generation device by increasing a quantity of light received by a semiconductor element array of the device and also increase the light emitting efficiency by reflecting the light generated at the rear side of the device towards the front side. SOLUTION: A solar battery array which is a plurality of serially connected solar battery cells 10, each having a photoelectromotive force generating section, is housed in a translucent case member 2. A reflector 5 is tightly installed on the rear side of the case member 2 and therefore the solar battery array can recieve not only the solar light 25 incident on the front side of the case member 2 but also the light reflected on the globular reflection surface 5a, and thus a quantity of light received by the solar battery array is increased and hence is the photoelectromotive force by the solar battery cells 10. |
