Abstract: A light pipe that can be employed for a Concentrator Photo-Voltaic (CPV) system is provided. The light pipe homogenizes light by diffusion and/or refraction, and can be embodied in a structure that has a low aspect ratio. The diffusion and/or refraction can be effected by concave or convex surfaces of a transparent medium that forms a body of the light pipe, by light diffracting particles, and/or by a diffracting surface. Optionally, multiple transparent media can be employed with a refracting and/or diffracting interface therebetween. The reduced aspect ratio of the light pipe can improve reliability of mechanical alignment in the CPV system as well as reducing the cost of manufacturing and/or aligning the light pipe within the CPV system.
