NOVELTY - A solar module comprises a solar concentrator structure using a single piece of polymeric and/or glass webbing including elongated concentrating units having a geometric light concentrator element coupled to one photovoltaic strip. The geometric light concentrator element has a geometric concentration characteristic with an aperture to exit ratio of 1.8-4.5 and the exit region includes two exit notches with a radius of curvature of 0.25 mm and less characterizing the corresponding two corner structures.    USE - A solar module.    ADVANTAGE - The use of concentrator helps the solar conversion module having less photovoltaic material per surface area (e.g. less than or equal to 80%, less than or equal to 50%) than conventional solar panel module.    DETAILED DESCRIPTION - A solar module comprises a solar cell concentrator structure having a thickness of glass material of 5-7 mm. The glass material has integrally formed concentrator elements with a first concentrator element (301) in a first shape having a first curved wall region. The first concentrator element has a first aperture region (304) and a first exit region (306) with a first back surface region. A second concentrator element (302) is configured in a second shape with a second curved wall region and formed with the first concentrator element. It has a second aperture region (308) and a second exit region (310) with a second back surface region. A separation region is provided between the concentrator elements. It is characterized by a width separating the first exit region from the second exit region. A second radius of curvature characterizes a region between the concentrator elements. It is less than 0.10 mm and greater than 0.001 mm. A geometric concentration of 1.8-4.5 characterizes the concentrator elements. A triangular shaped region with an apex (316) is defined by the second radius of curvature and a base defined by the separation region (312). A refractive index of 1 characterizes the triangular region. Photovoltaic devices comprise a first photovoltaic device comprising a first surface region coupled to the first exit region and a second photovoltaic device comprising a second surface region coupled to the second exit region. A first radius of curvature characterizes first comer structure (320). It is less than 0.10 mm and greater than 0.001 mm. The concentrator elements are characterized by a refractive index of greater than or equal to 1.4.
