摘要

本研究建立了太阳能热光子能量转换器（STEC）模型，并对其冷热两侧的能量平衡约束方程进行了数值求解，以揭示发光二极管（LED）和光伏电池（PV）的工作温度与热、电和结构参数的关系。在给定的半导体带隙 0.36 eV 和聚光器集中系数 20 的条件下，对发光二极管的偏置电压和光伏电池的输出电压进行了优化，以达到 STEC 13% 的局部最高效率。此外，还对条件进行了优化，以实现 15.94% 的整体最高效率。能量损耗的分布情况揭示了潜在的损耗机制。这项工作所获得的结果可为高效利用太阳能提供理论指导。

Parametric optimization and energy loss analysis of a solar thermophotonic energy converter

In the present work, the model of a solar thermophotonic energy converter (STEC) is established, of which the energy balance constraint equations at both the hot and cold sides are numerically solved to uncover the dependencies of the operating temperatures of the light emitting diode (LED) and photovoltaic (PV) cell on thermal, electrical, and structural parameters. For a given band-gap 0.36 eV of the semiconductor and a concentrated factor 20 of the concentrator, the LED’s bias voltage and the PV cell’s output voltage are optimized to achieve a local maximum efficiency 13% of the STEC. Furthermore, the conditions are optimized to attain an overall maximum efficiency of 15.94%. The distributions of energy losses are presented to reveal the underlying loss mechanisms. The results obtained in this work can provide theoretical guidance for the efficient utilization of solar energy.
