摘要

电池温度的升高会导致太阳能电池功率和效率的下降。温度每升高1℃,太阳能电池板的转换效率降低0.08%。因此,本研究通过实验研究了采用含金属泡沫和不含金属泡沫的相变材料(PCM)对低聚光太阳能电池(CPV)模块进行热调节的新型复合被动散热系统(HS)的不同结构:窝形(DHS)、平板(FHS)和梯形(THS)。在2800 W/m2的恒定太阳辐照水平下,系统的性能根据能源、能源、经济和环境方法进行评估。研究结果表明,与自然PV冷却相比,使用有和没有MF的PCM 26最大限度地降低了DHS冷却系统的电池温度,分别降低了55.6°C和53.4°C。DHS/MF-PCM 26冷却系统的最大电效率为12.6%,而DHS/MF-PCM 29的电池效率为12.44%。PV-DHS/MF-PCM 29系统达到最高的PCM和整体系统的火用效率,分别为5.43%和18.76%。与参考电池相比,PV-THS/MF-PCM 26系统的成本最低,节省了47.58%的成本,而PV-DHS/MF-PCM 26和PV-THS/MF-PCM 26分别节省了45.43%和44.76%的成本。PV-DHS/MF-PCM 26配置是最环保的选择,其碳信用收益为10.81美元,而MF-PCM 29为10.58美元。本研究的结果与以往研究的类似结果进行了比较。

Experimental work of low-concentrated solar cell cooled by different configurations of heat spreader/phase change material/metal foam: energy, exergy, environmental, and economic assessment.

The increase in the cell temperature results in a decrease in both solar cell power and efficiency. The conversion efficiency of the panels decreases by 0.08% for every 1°C rise in its temperature. Therefore, this study experimentally investigates the effect of using a new composite passive cooling system of heat spreader (HS) of different configurations: dimple (DHS), flat plate (FHS), and trapezoidal (THS), with phase change materials (PCM) including and non-including metal foam (MF) for the thermal regulation of low concentrated solar cell (CPV) modules. The system's performance is evaluated based on energy, exergy, economic, and environmental approaches under constant solar irradiance levels of 2800 W/m2. The findings reveal that utilizing PCM 26 with and without MF maximally reduces the cell temperature of the DHS cooling system by 55.6°C and 53.4°C, respectively, compared with natural PV cooling. The maximum electrical efficiency accounts for the DHS/MF-PCM 26 cooling system with 12.6%, while DHS/MF-PCM 29 archives a cell efficiency of 12.44%. PV-DHS/MF-PCM 29 system achieves the highest PCM and overall system exergy efficiencies of 5.43% and 18.76%, respectively. However, the PV-THS/MF-PCM 26 system achieves the minimum cost with a cost saving of 47.58% compared with the reference cell, while PV-DHS/MF-PCM 26 and PV-THS/MF-PCM 26 save 45.43% and 44.76%, respectively. The PV-DHS/MF-PCM 26 configuration is the most environmentally friendly option, with a carbon credit gain of 10.81$, compared with 10.58$ for MF-PCM 29. The results of the current study are compared with similar results from previous studies.
