摘　　要：介绍了分频型和联合型集成太阳能光伏发电和温差发电的复合系统的原理,分别建立了聚光光伏和温差发电系统的数学模型,对不同聚光比和换热系数下的发电系统效率进行了计算和比较。结果表明:分频型复合发电系统效率优于联合型复合发电系统。随着聚光比增大,在冷却良好条件下分频型复合发电系统总效率随之增大,而联合型复合发电系统的总效率随聚光比增大而降低;同时换热系数越高,发电系统的性能越好,但存在一限值。Two kinds of photovoltaic/thermoelectric solar hybrid systems were introduced,the thermal and power models of solar cells in concentration and thermoelectric were established,then the influence of focus ratio and heat transfer coefficient were analyzed.The results show that the efficiency of spectrum splitting hybrid system is better than combined system which the thermoelectric converters were attached to the back side of the PV modules.And with the increase of focus ratio,the efficiency of spectrum splitting hybrid system increased,while the combined system decreased.The higher the heat transfer coefficient,the higher the efficient of hybrid system,but there is a limit.
