中文摘要：
结合太阳能电池温度特性和温差发电特点,设计了一套新的太阳能光伏发电-温差发电驱动的冰箱模型,该模型包括太阳能光伏电池、半导体温差发电模块、电源控制系统等.根据负载用电需求,做出了光伏发电系统的设计方案.采用热力学基本理论,对该模型进行了工作效率及火用效率的分析.结果发现：能效比COP达到了2.73（一般冰箱COP为2左右）,火用效率也达到42.5%.同时,该系统模型环境效益明显,可以减排CO21394.2kg,SO227.2kg,氮氧化物21.0kg.这对可再生能源的应用具有理论指导意义。
英文摘要：
According to solar cell＇s temperature properties and thermoelectric power properties,a refrigerator model is newly designed,which is driven by solar photovoltaic and thermoelectric power generation.It includes solar cells,thermoelectric power modules,power control system,etc.Based on the load demand for electricity,a photovoltaic power generation system is designed.The operating efficiency and exergy efficiency of the model are analyzed by thermodynamic theory.We find that the COP（coefficient of performance） achieves 2.73（COP is about 2 for general refrigerators） and exergy efficiency achieves 42.5%.By using the model,the emissions of carbon dioxide 1394.2 kg,sulfur dioxide 27.2 kg and nitrogen oxides 21.0 kg are reduced,which can provide an interesting direction to the applications of renewable energy.
