摘要

利用吸收-发射模块，太阳能热光伏(STPV)系统有可能突破Shockley-Queisser极限。高效的光谱选择性和高温耐久性是该技术的关键。本文设计了一种基于耐火材料纳米结构的高效选择性吸收-发射组件，用于太阳能热光伏发电。数值模拟结果表明，该吸收-发射模块能够在带隙以上以最优带宽提供指定的窄带发射光谱，并且具有鲁棒性，不受入射角和偏振的影响。根据详细的平衡计算，在广泛的组件温度范围内，我们设计的太阳能电池效率可以超过Shockley-Queisser极限41%。

A NANOSTRUCTURE-BASED HIGH-TEMPERATURE SELECTIVE ABSORBER-EMITTER PAIR FOR A SOLAR THERMOPHOTOVOLTAIC SYSTEM WITH NARROWBAND THERMAL EMISSION

Using absorber-emitter modules, solar thermophotovoltaic (STPV) systems could potentially break through the Shockley-Queisser limit. Efficient spectral selectivity and high temperature endurance are the keys to this technology. In this paper, a high-efficiency selective absorberemitter module based on refractory material nanostructures is designed for solar thermophotovoltaic applications. Our numerical simulations show that the proposed absorber-emitter module could provide a specified narrowband emission spectrum above the bandgap with optimal bandwidth, and its performance is robust and independent of incident angle and polarization. According to detailed balance calculations, over a broad range of module temperatures, the solar cell efficiency of our design could surpass the Shockley-Queisser limit by 41%.
