中文摘要：
实验研究了聚光太阳电池上光照强度、短路电流、开路电压、电池温度和光电转换效率随菲涅耳透镜与电池的距离变化关系。结果表明,聚光条件下,太阳电池性能的提高主要源于短路电流的变化,而不是开路电压;聚光后,太阳电池与透镜距离为焦长时,输出功率可以达到最大值;太阳电池的最大单位光强转换效率需要把太阳电池放到透镜焦点前。本文研究结果对于聚光光伏系统的研制具有指导意义。
英文摘要：
The dependences of light intensity,open-circuit voltage,short circuit current and cell′s temperature on the distance between the Fresnel lens and solar cell are investigated in concentrating photovoltaic system.The results show that the efficiency increase of concentrating photovoltaic system mainly results from the improvement of the short-circuit current,but not from the open-circuit voltage.It is found that the output power of solar cell can achieve maximum when the cell is placed at the focal point of the Fresnel lens.But the maximum efficiency of a concentrating photovoltaic cell per unit of light intensity can be obtained only when the cell is placed before the lens focus.It is of great guiding significance for the design and research of the current photovoltaic systems.
