摘　　要：当前世界能源形势日趋紧张,太阳能作为重要的可再生能源之一,其开发利用和能效提升对于国民经济和能源安全尤为重要,而太阳能光伏板的温度提升是影响能效和使用寿命的重要因素。本文对近年来风冷和水冷等传统平板光伏冷却的研究进展进行了总结和分类,同时对蒸发冷却、热电冷却、辐射冷却、相变材料冷却等新型平板光伏散热方式进行了梳理和分析。此外,文中引入了传热热阻的概念,通过计算以上6种冷却散热技术具体应用的热阻或光伏板与环境温度之间的温差,从热阻的角度重点分析了采用上述6种冷却方式对光伏板产生的冷却效果,同时从能效提升及运行温度等方面对比分析了不同冷却方式的优点和不足,以期为太阳能光伏电池冷却散热技术的进一步研究与优化提供相关参考和借鉴。With the energy shortage getting more and more serious and solar energy as one of the important sustainable energy,the utilization and performance of photovoltaic（PV）cells is becoming a promising solution for economics and energy security. While,the conversion efficiency of PV module lies in reducing the cell＇s operating temperature and temperature gradient. In this paper the summary and sorting were made of recent research progress for PV cooling technologies,mainly including traditional plat PV cooling technologies as air cooling and water cooling and advanced cooling technologies as evaporative cooling,thermoelectric cooling,radiation cooling and phase change materials cooling. The heat transfer resistance between PV panel and environment was introduced to characterize the heat transfer amount. The thermal resistance or temperature difference between PV panel and environment of all the above cooling technologies was calculated in order to emphatically analyze cooling performance from thermal resistance perspective. Moreover,the advantages and disadvantages of different cooling methods were also evaluated from points of thermal resistance or temperature difference,efficiency improvement and operating temperature in order to provide reference for the further research.
