Abstract
For the purpose of providing a solar module which has a fixed type solar concentrator of high converging magnification, a solar cell 12 is installed on the bottom face of an extension 30 which is extended further from the apex of a V shape formed by a pair of prisms having a refractive index larger than that of air, and a mirror surface 18 is formed on the back side of an incident surface 20 on which sunlight 10 falls. The mirror surface 18 and the incident surface 20 are formed in such a manner that their distance widens toward the apex of the V shape. The sunlight 10 incident on the prisms 16 performs reflection on the mirror surface 18 and total internal reflection on the incident surface 20, respectively. After repeating such reflection, the sunlight 10 reaches the bottom of the extension 30, where it emerges as outgoing light 22 to the solar cell 12.
