Low concentration photovoltaic systems based on small-scale linear Fresnel reflectors: Development of a new sawtooth V-trough concentrator

Abstract

This study focuses on the design of the receiver cavity of a small-scale linear Fresnel reflector used as sunlight collector in a lowconcentration photovoltaic system. Since photo-voltaic cells require uniform illumination over their entire surface for their correct operation, this will be the key point of the design. This work aims to investigate the geometry of a new sawtooth Vtrough cavity. The design is first carried out from a theoretical point of view, obtaining the general equations. These equations will be verified using the Monte Carlo Ray Tracing method. The SolTrace™ software will be used for this purpose.
