摘要
设计并搭建了一种碟式聚光光伏发电系统,介绍了系统的结构,阐述了系统工作原理,并对其进行了户外实验研究。根据实验结果,该碟式聚光光伏系统的几何聚光倍数为150倍,其峰值功率为1.5315W/cm2,平均效率为26.58%,电池平均工作温度为46.875℃。太阳直接辐射强度和电池温度是影响三结砷化镓光伏电池性能的主要因素。与现有的单晶硅光伏电池片相比,三结砷化镓聚光光伏电池具有转换效率高、电学性能好等特点,所收集的电池温度、输出功率、效率等数据对碟式聚光光伏系统的进一步研究具有一定参考价值。
A dish-style concentrating photovoltaic system was designed and built in this article. The concentration ratio of this system was 150 and the photovohaic cell was cooled by heat pipe. The author measured the performance of triple-junction InGaP/InGaAs/Ge solar cell. According to experiment result, the peak output power of the system was 1. 5315W/cm2, the average output power was 1.20W/cm2 and the average efficiency was 26.58%, the aver- age working temperature was 46. 875℃ and the maximum working temperature didn＇t exceed 62.05℃. The influ- encing factors of the InGaP/InGaAs/Ge triple-junction solar cell electrical properties mainly include direct solar ra- diation and solar cell temperature. This system had its own advantage comparing to existing stationary photovohaic system such as high efficiency and better electrical performance. The cell temperature, output power and efficiency were collected in this experiment which would be valuable reference for further research.
