Patent ID: 8168884

Claim:
A solar cell module comprising a solar cell concentrator structure, the solar cell concentrator structure comprising: a pair of concentrator elements formed from a thickness of glass material comprising a first concentrator element, the first concentrator element including a first aperture region and a first exit region, the first exit region including a first back surface region and a second concentrator element integrally formed with the first concentrator element, the second concentrator element including a second aperture region and a second exit region, the second exit region including a second back surface region, the thickness of glass material ranging from 5 to 7 mm; a first coupling region between the first exit region and a first surface region of a first photovoltaic device and a second coupling region between the second exit region and a second surface region of a second photovoltaic device; a separation region provided between the first concentrator element and the second concentrator element, the separation region being characterized by a width separating the first exit region from the second exit region; a radius of curvature characterizing a region between the first concentrator element and the second concentrator element, the radius of curvature being less than about 0.15 mm and greater than 0.001 mm and configured to reduce a scattering effect of a portion of an incident electromagnetic radiation; a triangular shaped region including an apex defined by the radius of curvature and a base defined by the separation region; and a refractive index of about 1 characterizing the triangular region.
