- Abstract
The feasibility of increasing the concentration ratio and expanding the misorientation curve using secondary lens elements is considered for solar modules with triple-junction InGaP/GaAs/Ge photovoltaic converters and radiation-concentrating Fresnel lenses. Composite glass-silicone Fresnel lenses measuring 40 × 40 and 60 × 60 mm (plan view) with focal lengths of 70 and 110 mm, respectively, are used as primary concentrators. The focal length of secondary plane-convex glass lenses is varied from 5 to 25 mm. With the shortest-focal-length secondary lenses used, measurements of the parameters of the photovoltaic converter in a system with radiation concentrators that were made with a pulsed solar tester show the increase in the concentration ratio and the expansion of the misorientation curve by a factor of 2.5–3.0. The parameters of test modules with lens panels measured under solar illumination are found to be in good agreement with laboratory data.
