Abstract: A single-stack, solar power receiver comprising both a thermal absorber layer and a photovoltaic cell layer. The stack includes an aerogel layer, that is optically transparent and thermally insulating (“OTTI”); a spectrally selective high thermal conductivity (“SSTC”) thermal absorber layer; a bottom OTTI layer; and a PV cell layer. The SSTC layer includes a set of fins that substantially blocks solar radiation absorption in the band where PV cells are most sensitive. Photons with energies above or below this band block range are absorbed by the fins and the absorbed heat is conducted to pipes in the fin structure carrying a heated thermal working fluid to heat storage. Photons with energy in the band block range are reflected by the SSTC fins to the PV cell layer. The bottom OTTI aerogel layer keeps the PV cell operating near ambient temperature. The PV cell converts incident solar radiation to electrical energy.

Abstract translation: 包括热吸收层和光伏电池层的单层太阳能电力接收器。 该堆叠包括光学透明和隔热（“OTTI”）的气凝胶层; 光谱选择性高导热性（“SSTC”）热吸收层; 底层OTTI层; 和PV电池层。 SSTC层包括一组翅片，其基本上阻挡了太阳能电池最敏感的带中的太阳辐射吸收。 具有高于或低于该带阻挡范围的能量的光子被翅片吸收，并且吸收的热量传导到带有加热的热工作流体的翅片结构中的管道以进行储热。 在带阻范围内具有能量的光子被SSTC散热片反射到PV电池层。 底部OTTI气凝胶层使PV电池在环境温度附近工作。 PV电池将入射的太阳辐射转换成电能。
