设计了高温、紫外及温度紫外耦合实验考察丙三醇的耐候性.利用紫外可见光谱仪、红外光谱仪检测实验前后丙i醇性质的变化,并测试了液浸硅电池的电性能和表面形貌的变化.结果表明,实验后丙三醇的光谱透过率在小于600nm的低波段有所降低,红外光谱显示其发生了氧化反应生成微最的羰基.用丙三醇液浸硅电池的电性能没有衰降,但是电池表面出现了微量颗粒状物质.用理论分析了液体性质变化的原因,并由此建议醇类液体不适于在液浸光伏系统中作为冷却液体.

In order to efficient cooling in CPV system, Glycerol was used in this paper for cooling solar cells by direct immersing the cells in it. High temperature tests (85℃ and 150℃ ), UV-light test and high temperature and UV coupling test were designed for investigating the weather-resistance of glycerol. The changes of glycerol after tests were measured by UV-Vis and FT-IR spectra, also the Voc, Isc and the surface of the immersing cells were measured before and after tests.The results indicated that the transmittance began to decrease at about 600nm and trace of carbonyl was produced by oxidation reaction in glycerol. No electrical degradation in immersed Si cells was investigated and only minim substance of varied shape and size appeared on the surface of cells. It is advised that alcohols liquid is unsuitable as cooling liquid in liquid-immersing CPV system based on the analysis of the phenomena.
