阐述了太阳能电池特性的相关理论，用实验方法研究了太阳能电池开路电压、短路电流、最大输出功率、最佳负载电阻及填充因子与光照强度的关系，结果表明，太阳能电池的开路电压、短路电流、最大输出功率随光照强度的增强而增大， 最佳负载电阻和填充因子随光照强度的增强而减小，其中随着光照强度减弱而最佳负载电阻增大并未发现有相关的理论分析或仿真结果的报道，其他结果与太阳能电池特性相关理论一致.

The correlation theory of characteristics of solar battery is represented，the relationships between open-circuit voltage，short -circuit current，optimum output power，optimum load resistance，packing factor of solar battery and light strength are studied by the experimental method. The results show that the open-circuit voltage， short-circuit current and maximum output power increase with the increase of light intensity，and optimum load resistance，packing factor decrease with increasing light intensity. It is shown that with weakening the light strength and increasing the optimum load resistance，which did not report for relevant theoretical analysis or simulation results. The other results are consistent with the correlation theory of characteristics of solar battery.
