Abstract
As a structure of a concentrator photovoltaic module, a ribbon-shaped flexible printed circuit is arranged along a bottom surface of a vessel-shaped housing. The flexible printed circuit includes a solar cell on a flexible substrate having flexibility, and furthermore, can also include a concentrating portion (a secondary concentrating portion) for concentrating incident sunlight onto the solar cell. Moreover, a primary concentrating portion having a Fresnel lens is attached to the housing side.
