摘　　要：太阳电池工作时,温度是影响电池转换效率的重要因素之一.硅太阳电池温度特性决定着当温度升高时,电池输出功率降低：电池温度每升高1K,功率输出减少0.4％ ～0.5％,效率同比下降0.08％～0.1％.本文以硅太阳电池组件为例,按照导出热量方式的不同,将硅太阳电池冷却分为空气冷却、水冷却、制冷工质冷却、混合冷却等四种方式.着重介绍了几种国内外硅太阳电池的冷却技术、方法的研究成果,说明各种方法、技术的工作原理,并加以对比,得出结论：分频冷却技术从原理上讲冷却效果较好.文末展望了未来几种新型冷却技术.The temperature is one of the important factors that influence the battery conversion efficiency when solar cells work. Due to the temperature characteristics of silicon solar cell, the battery power out- put is reduced with the temperature rises. As the temperature risesl degree, the power output of battery reducs 0.4% - 0.5% and 0.08% ~ 0.1% of efficiency. Based on exporting the heat different, it has been divided into four ways to the silicon solar cell components＇ cooling：the air cooling, the water cool- , the refrigerating agent cooling and the combined cooling. The article introduces several kinds of cool- technologies and methods about silicon solar cell at home and abroad and illustrates their principle. the end of this article, we look forward several new cooling technologies.
