Description
Summary:In this paper we will describe a concentrating photovoltaic (CPV) system featuring spectral separation of the solar radiation. The newly designed concentrator structure provides both the spectral separation and the solar light concentration. The two caustics generated by the CPV system are spaced apart in such a way to illuminate two dense arrays of single junction Si and InGaP cells. Each of these PV receivers operate in a spectral region where its solar cells best perform, and thus they can be optimized independently of each other. Tuning the cutoff wavelength of the spectral separation system, the overall system efficiency is expected to reach 29.5% even with simple single‐junctions PV receivers.
