Search for the optimal solution for the optical system of the “micro-CPV”-module

This work is devoted to studying optical-energy characteristics of the micro-concentrator module optical part and searching for the design optimal according to criterion “the maximum average sunlight concentration in the minimum-radius focal spot”. The results of optimizing the lenses showed that the optimal solution for the micro-CPV module is an optical system made of a biconvex lens having twice the concentrating power at a focal length shorter than that of a plano-convex lens of the same dimensions.
