Temperature characteristics is considered to be one of the most important characters affecting solar cell performance, especially those operating under concentrated solar radiation. After expatiation on the temperature characteristics of PV system, the choice basis and standard of concentration photovoltaic system is introduced. The particular temperature characteristics of concentration photovoltaic system which is different from normal PV system are analyzed. Nonuniformly temperature distribution's influence on PV system's electrical characteristics, which is caused by nonuniformly concentrated solar radiation, is discussed. The influence of thermal circle on thermal stress and the system's performance stability, in concentration PV system, are made an analysis. The result indicates that it is very important to consider the temperature characteristics as the inherent characters in the PV system. Cooling of photovoltaic cells is considered as one of the main concerns when designing concentration photovoltaic systems. In this paper, different ways of using system's thermal energy, and the major methods and work features for concentrated solar cells cooling system in the domestic and abroad are summarized, in order to provide the foundation of improving the efficiency of the concentrated photovoltaic systems.
