Al2O3/石墨烯/PVDF-HFP辐射冷却涂层增强BIPV组件散热
Al2O3/graphene/PVDF-HFP radiative cooling coating reinforced heat dissipation of BIPV modules
中文简介
建筑一体化光伏组件，应用于工商业建筑，一般采用金属作为背板。夏季，组件工作温度高达70℃，导致输出功率和使用寿命不稳定。因此，降低光伏组件的工作温度非常重要。本工作制备了Al 2 O 3 /石墨烯/聚偏二氟乙烯-六氟丙烯(PVDF-HFP)复合辐射冷却涂层，并将其用于增强光伏组件的散热。结果表明，0.75 wt%Al 2 O 3 /1wt%石墨烯/PVDF-HFP复合涂层的热扩散率为3.24 μm 2 /s，平均发射率为0.94。外门涂层最高温降达到5.8℃。此外，涂覆该复合涂层的微型光伏组件实现了2.4℃的冷却效果，输出功率和转换效率分别提高了5.8%和7%。这表明导热辐射冷却涂层在提高光伏组件可靠性方面具有潜在的应用前景。

Therefore, it is very important to reduce the operating temperature of photovoltaic modules. In this work, Al2O3/graphene/poly(vinylidene fluoride-co-hexafluoropropylene) (PVDF-HFP) composite radiative cooling coatings were prepared and utilized for reinforcing heat dissipation of photovoltaic modules. The results indicate that 0.75 wt%Al2O3/1wt%graphene/PVDF-HFP composite coating exhibited a thermal diffusivity
