FIELD: physics.
SUBSTANCE: proposed module comprises solar radiation concentrator made up of Fresnel lens with concentric working profile, photo transducer arranged at the lens focal plane, secondary reflector arranged ahead of said photo transducer. Note that photo transducer is located on cooling device surface. Fresnel lens consists of four zones of working profile, each with point optical focus in the plane of high-voltage square photo transducer. Note that focuses are located on diagonals of photo transducer between central point and apices of transducer square, while distance between focuses of said zones do not exceed 0.5, where d is diametre of focal spot produced by Fresnel lens peripheral zone. Note also that lenses have equal areas of midsections, while outlet opening of secondary reflector features square shape and area equal to or exceeding photo transducer area.
EFFECT: increased efficiency and reduced costs.
