摘要

太阳能可再生能源的开发利用被认为是缓解全球能源危机与环境压力的重要途径。然而，传统太阳能利用系统仍面临多重技术瓶颈，如光伏光电转换效率受其温度影响、系统综合能效偏低、能量产需时空失配等。因此，本研究提出一种耦合多层微通道与定形相变材料的温控-蓄热一体式光伏/热系统。通过搭建实验测试平台，对比分析了光伏系统、常规光伏-相变材料系统及新型耦合系统的热电性能，并重点探讨了太阳辐照度、工质流量、相变材料质量等关键参数对系统运行特性的影响规律。实验结果表明，该温控-蓄热一体式光伏/热系统展现出优异的综合性能。在1000 W/m

太阳辐照度下，光伏电池最高工作温度可以控制在55.3℃以内，系统平均电效率和平均热效率分别达到12.8%和24.7%。通过实验对比可知，常规光伏系统和光伏-相变材料复合系统的整体效率分别为29.2%和46.2%，而本系统的最高整体效率可达58.3%。进一步分析发现，随着太阳辐照度的增加，系统电效率、热效率及整体效率呈下降趋势，但最大输出功率持续提升。此外，提高微通道内工质流量以及增加相变材料的装载质量，可显著降低光伏组件工作温度，并增强系统的电效率与热效率。另一方面，在无太阳辐照条件下，该系统能够有效延缓相变材料的冷却凝固过程。与常规光伏/热系统相比，储热单元保温时间从78 min可以延长至154 min。

Abstract

The development and utilization of solar energy

a clean resource

is regarded as a crucial approach to alleviate the global energy crisis and environmental pressure. However

traditional solar energy utilization systems still face multiple technical bottlenecks

such as the photoelectric conversion efficiency being affected by temperature

low comprehensive energy efficiency of the system

and the temporal and spatial mismatch between energy supply and demand. Therefore

this paper proposes an integrated temperature control and heat storage photovoltaic/thermal system combining multi-layer microchannels and shaped phase change materials. An experimental test platform was constructed to compare and analyze the thermoelectric performance of a conventional PV system

a PV-PCM hybrid system

and the novel integrated system proposed in this study. The effects of key parameters

including solar irradiance

working fluid flow rate

and PCM mass

on the operational characteristics of the system were emphatically investigated. The experimental results demonstrate that the integrated temperature control and heat storage PV/T system exhibits excellent comprehensive performance. At a solar irradiance of 1000 W/m

the maximum operating temperature of the PV cells can be controlled within 55.3℃

and the electrical and thermal efficiencies of the system reach 12.8% and 24.7%

respectively. Compared with the conventional PV system and the PV-PCM hybrid system

the overall efficiency of the proposed system is increased by 29.2% and 46.2%

respectively

with a maximum value of 58.3%. Further analysis reveals that with the increase in so

lar irradiance

the electrical efficiency

thermal efficiency

and overall efficiency of the system show a downward trend

while the maximum output power continues to rise. In addition

increasing the working fluid flow rate in the microchannels and the loading mass of PCM can significantly reduce the operating temperature of the PV module and enhance the electrical and thermal efficiencies of the system. On the other hand

under non-solar irradiance conditions

the system can effectively delay the cooling and solidification process of the PCM. Compared with the traditional PV/T system

the thermal retention time of the heat storage unit is extended from 78 min to 154 min.
