This method is a particular application of photic field theory. This method uses the parameterization of a given primary optics, including actual tolerances of the manufacturing process. The design of the secondary optics is constrained by the selection of primary optics and maximizes the concentration at a previously specified collection area. The geometry of the secondary element is calculated by using a virtual source, which sends light in a first concentration step. This allows us to calculate the line flow for this specific case. This concept allows designing more compact and efficient secondary optics of photovoltaic systems.engjournal articlehttp://dx.doi.org/10.1117/12.2187962http://proceedings.spiedigitallibrary.org/proceeding.aspx?articleid=2432124open access535620.91Solar EnergyOpticsPhotovoltaic SystemÓptica (Física)Medio ambiente2209.19 Óptica Física2391 Química Ambiental
