In this paper we present a novel manufacturing method to produce achromatic Fresnel lenses for photovoltaic application.These achromatic lenses are capable of reaching a concentration factor three times higher than that attained by a conventional Silicone-on-Glass (SOG) Fresnel lens.The manufacturing method presented to fabricate the achromatic lens, which we refer to as Achromatic Doublet on Glass (ADG) Fresnel lens, is simple, cost-effective and highly scalable.A comprehensive ray-tracing analysis and its comparison with experimental results is presented in this work.
