摘　　要：光伏-热电混合发电系统是一种具有潜力的太阳能发电技术,然而传统串联式的光伏-热电发电系统存在器件运行温度不匹配和传热热阻较大的问题。本文提出了一种双面型具有三明治结构的光伏-热电混合发电系统,并搭建了相应的实验测试装置,在室内稳态条件下研究了不同辐照强度,冷却水流量对新型系统性能的影响。实验数据表明,双面型系统中光伏组件和热电发电器件的输出功率都要优于传统串联式系统。同时,提高辐照强度可以增加系统发电能力但会降低光伏发电效率,提高冷却水流量可以进一步提升系统输出性能。The photovoltaic-thermoelectric hybrid power generation system is a promising solar energy technology.However,traditional series-connected photovoltaic-thermoelectric system faces challenges such as mismatched device operating temperature and high thermal resistance.In this study,a bifacial type photovoltaic-thermoelectric hybrid power generation system with a sandwich-like configuration is proposed.An experimental setup is constructed to investigate the effects of different irradiance levels and cooling water flow rates on the performance of the new system under steady-state indoor conditions.Experimental data shows that the output power of photovoltaic module and thermoelectric device in bifacial type system is superior to that of traditional series system.Moreover,increasing irradiance levels can enhance the system’s power generation capacity but may reduce the photovoltaic power generation efficiency.Additionally,increasing the cooling water flow rate can further enhance the system’s output performance.
