Research on Optimal Design of Thermal Emitter Based on Thermal Photovoltaic Technology

Improving the thermal conversion efficiency of photovoltaic system to optimize design emitter in thermophotovoltaic has attracted worldwide attention recent years due world’s major power have devoted great efforts exploration outer space. Based on this background, focus study is adjust emission spectrum improve thermoelectric system. Aiming at problems and material characteristics, model TMM transfer matrix established, solving radiation calculating Maxwell equation are solved. Use appendix website: https://refractiveindex.info/, transmittance 50 nm thick tungsten wavelength 0.3 ~ 5 μ m obtained draw tungsten. According analysis people's Republic China, it verified be within a reasonable range. characteristics composite structures, transmission established. The coherent light reflection multilayer structure expressed as product matrix. relationship between properties its obtained, problem
