Secondary optics for the “micro-CPV” system

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