| 摘要 |
A photovoltaic module comprising an array of electrically interconnected photovoltaic cells (4) disposed in a planar and mutually spaced relationship between a light-transparent front cover member and a back sheet is provided with a light-reflecting means (30B, 30C, 30D) disposed between adjacent cells for reflecting light falling in the areas between cells back toward said transparent cover member for further internal reflection onto the solar cells (4). The light-reflecting means comprises a flexible plastic film that has been embossed so as to have a plurality of small V-shaped grooves (26) in its front surface, and a thin light-reflecting coating on said front surface, the portion of said coating along the sides of said grooves (26) forming light-reflective facets, said grooves (26) being formed so that said facets will reflect light impinging thereon back into said transparent cover sheet with an angle of incidence greater than the critical angle. |
