摘　　要：聚光光伏电池的高效、稳定和安全运行依赖于有效冷却技术。常规的聚光光伏电池主动冷却技术需消耗部分光伏电池产生的电能,因而间接降低有效电力输出。据此,文章基于热电模块提出一种聚光光伏电池的自冷却概念设计,并通过热电模块的性能测试实验验证了设计可行性。测试表明,单个56 mm×56 mm热电模块在90℃热源加热条件下的最大开路电压为3.6 V,输出功率为0.97 W。此后,针对10 kW系统进行了参数设计,计算结果表明,整个装置的热电模块总开路电压可达212.6 V,供给冷却模块的输出功率可达706.5 W,满足聚光光伏电池散热的能耗需求。An efficient,stable and safe operation on the concentrated photovoltaic(CPV)cells relies on the effective cooling.A conventional active cooling for CPV cells consumes a part of generated power,and thus indirectly decreases the effective power output.Accordingly,a conceptual design with self-cooling for CPV cells is proposed based on thermoelectric modules,and its feasibility is verified by the performance test.The test results showed that a single 56 mm×56 mm thermoelectric module has a maximum open circuit voltage of 3.6 V and a maximum output power of 0.97 W under the heating temperature of 90℃.A parameter design of the 10 kW CPV system was then conducted.The calculation results showed that the open circuit voltage of the thermoelectric modules in the entire device is 212.6 V.The output power supplied to the cooling module reaches up to 706.5 W,which meets the electricity consumption demand of heat dissipation for CPV cells.
