建立了一个评价聚光光伏-热电（PV-TE）复合系统效率的理论模型。研究了晶体硅光伏电池、硅薄膜光伏电池、聚合物光伏电池和铜铟镓硒光伏电池的混合系统。从半导体方程出发，考虑了温度对电池效率的影响，揭示了聚合物光伏电池不同效率的温度特性。通过对对流换热系数和聚光比的优化，证明了多晶硅薄膜光伏电池适用于聚光光伏-热电联产系统。聚合物光伏电池被证明是适用于非聚光PV-TE混合系统。
A theoretical model for evaluating the efficiency of concentrating PV–TE (photovoltaic–thermoelectric) hybrid system is developed in this paper. Hybrid systems with different photovoltaic cells are studied, including crystalline silicon photovoltaic cell, silicon thin-film photovoltaic cell, polymer photovoltaic cell and copper indium gallium selenide photovoltaic cell. The influence of temperature on the efficiency of photovoltaic cell has been taken into account based on the semiconductor equations, which reveals different efficiency temperature characteristic of polymer photovoltaic cells. It is demonstrated that the polycrystalline silicon thin-film photovoltaic cell is suitable for concentrating PV–TE hybrid system through optimization of the convection heat transfer coefficient and concentrating ratio. The polymer photovoltaic cell is proved to be suitable for non-concentrating PV–TE hybrid system.
