Abstract

Photovoltaic technology has been widely used in spacecraft power supply, but its efficiency is difficult to be greatly improved by Shockley-Queisser limitation. The thermophotovoltaic technology can convert solar radiation energy or high-temperature combustion energy into radiation energy with reshaped spectrum for direct photovoltaic power generation. In this study, a meta-material structure composed of metal Ta and dielectric SiO2 is innovatively proposed for shaping narrowband radiation. The results show that the optimized spectral emittance peak of narrowband emitters reaches 0.9998. Narrowband emitter has advantages at high temperatures above 1000 K. The thermophotovoltaic efficiency of InGaAsSb cell and tandem Si/InGaAsSb cells can reach more than 41.67% and 46.26%, respectively. It is significantly higher than published thermophotovoltaic system with broadband emitter. This study demonstrates the notable advantages and potential of narrowband emitter for spectrum reshaping, which provides an important reference for future spacecraft power supply as well as space solar power generation.

基于超材料窄带发射极的空间电源高效热光伏系统设计

光伏技术已广泛应用于航天器供电，但由于Shockley-Queisser限制，其效率难以大幅提高。热光伏技术可以将太阳辐射能或高温燃烧能转化为重塑光谱的辐射能，用于直接光伏发电。在本研究中，创新地提出了一种由金属Ta和介质SiO2组成的超材料结构，用于窄带辐射的整形。结果表明，优化后窄带发射体的光谱发射度峰值达到0.9998。窄带发射极在1000 K以上的高温下具有优势。InGaAsSb电池和Si/InGaAsSb串联电池的热光伏效率分别可以达到41.67%和46.26%以上。它明显高于已有的宽带发射极热光伏系统。研究表明窄带发射体在频谱重构方面具有显著的优势和潜力，为未来航天器供电和空间太阳能发电提供了重要参考。

期刊介绍： The main aims of Thermal Science to publish papers giving results of the fundamental and applied research in different, but closely connected fields: fluid mechanics (mainly turbulent flows), heat transfer, mass transfer, combustion and chemical processes in single, and specifically in multi-phase and multi-component flows in high-temperature chemically reacting flows processes present in thermal engineering, energy generating or consuming equipment, process and chemical engineering equipment and devices, ecological engineering, The important characteristic of the journal is the orientation to the fundamental results of the investigations of different physical and chemical processes, always jointly present in real conditions, and their mutual influence. To publish papers written by experts from different fields: mechanical engineering, chemical engineering, fluid dynamics, thermodynamics and related fields. To inform international scientific community about the recent, and most prominent fundamental results achieved in the South-East European region, and particularly in Serbia, and - vice versa - to inform the scientific community from South-East European Region about recent fundamental and applied scientific achievements in developed countries, serving as a basis for technology development. To achieve international standards of the published papers, by the engagement of experts from different countries in the International Advisory board.
