Kind Code:
A1
Abstract:
A photovoltaic power generation system has a light incident surface into which external light enters, a light-guiding body having a light emission surface, not parallel to the incident surface, for emitting the external light, and at least one photoelectric conversion element provided so as to face the light emission surface. The light-guiding body has reflection bodies for reflecting light entered into inside the light-guiding body to at least either the light incident surface or the light emission surface. The system is simple in structure, has no movable parts, which tend to cause failure, and can be installed at any place.
