Abstract
The paper presents a novel Fresnel lens for concentrator photovoltaic (CPV) technologies with reduced chromatic aberration that allows increasing the attainable concentration. Although achromatic doublets for CPV have previously been proposed, they were based on coupling two plastic materials but no practical fabrication procedure was described. Here we present for the first time a cost-effective manufacturing process consisting in laminating a high-dispersion plastic, a low-dispersion elastomer and a rigid glass substrate. Ray-tracing simulations showed a concentration factor three times higher than that attained by a classic Silicone On Glass (SOG) Fresnel len...
