STUDY ON THE ELECTRICAL PROPERTIES OF METAL BACKPLANE MONOCRYSTALLINE SILICON PV COMPONENTS

为提高太阳电池组件的电输出,选择热阻小、散热快的5052型铝合金作为光伏组件的背板材料。通过试制小面积金属光伏组件,其绝缘性和粘接性能达到使用要求。分析光伏组件中电池的温度来源,建立组件一维传热模型,并模拟计算了金属和TPT背板材料光伏组件在不同工况下,电池的工作温度及输出功率。1200mm×800mm金属背板组件与TPT背板组件对比试验表明,金属背板组件电池温度较TPT背板组件有明显降低,平均降低了6.48℃,而输出功率和发电量增量均提高了4%。

Type 5052 aluminum alloy with small heat resistance and quick heat dissipation has been selected as the backplane of photovoltaic components to improve PV components electricity output. The insulation and adhesive property can entirely reach security requirements by conducting small area of metal PV module experiments. One- dimensional thermal model of PV components has been developed based on the analysis of cell temperature source. The cell temperature and output power of PV components with metal and TPT backplane under different conditions have been calculated. Experimental test from the 1200mm× 800mm PV components with metal and TPT backplane shown that the former cell temperature is 6. 48℃ lower than the latter one while the output power and power genera- tion have been enhanced by more 4%.
