摘　　要：为提高光伏光热一体化系统(PV/T)能量输出,将新型铝合金背板型光伏组件和自行设计制作的不锈钢扁盒流道集热板相结合,用导热硅胶加以粘接构成新型PV/T复合系统。将新型PV/T复合系统、常规TPT背板光伏组件、常规平板集热器至于同于工况下进行测试,测试结果表明,与TPT光伏组件相比,新型PV/T系统的电压约提升了0.5～1.5V,电转换效率、填充因子、输出功率及发电量平均提高了9.76%、1.49%、3.75%、4.02%。而复合系统热效率比常规平板集热器约低22%左右。相对于常规TPT光伏系统或自然循环平板集热器热水系统,新型PV/T系统有发电量高、占地面积小、综合性能效率高等优点。To improve PV/T energy output performance, a novel hybrid photovoltaic/thermal solar system is designed with flat stainless box as solar heat collector combined with aluminum alloy backplane monocrystalline silicon PV com- ponents. Experiments are conducted on the novel PV/T sys- tem, PV module and solar heat collector at same condition. Experimental results show that the electrical performances are compared between novel PV/T and conventional PV module. The voltage electrical efficiency, fill factor, output power and power generation of novel PV/T system have re- spectively been enhanced about 0.5-1.5V, 9.76%, 1.49%, 3.75% and 4.02%, but thermal efficiency of PV/ T system have been reduced about 22%. Compared with pure PV system or the nature circulation of the solar water collector, Novel PV/T system has other advantages, such as less occupied area, higher total performance efficiency, greater power generation and better efficiency of integratedperformance.
