摘　　要：为了充分发挥太阳能电池供电作用,以光照强度作为干扰因素,探究不同光照条件下电池性能特征。实验以转动电池角度方式模拟光照强度变化环境,测量短路电流、开路电压,并计算不同条件下的电池最大输出功率、填充因子,记录负载电阻阻值。实验结果表明,光照逐渐减弱过程中,填充因子、最佳负载电阻随之增加,最大输出功率随之减小,该实验结果与理论特性结论相符。In order to give full play to the role of solar battery power supply,this article uses light intensity as an interference factor to explore battery performance characteristics under different light conditions.This experiment simulates the changing environment of light intensity by rotating the battery angle,measuring short-circuit current,open circuit voltage,and calculating the maximum output power and filling factor of the battery under different conditions,and recording the load resistance.The experimental results show that in the process of gradual weakening of the light,the fill factor and the optimal load resistance increase,and the maximum output power decreases accordingly.The experimental results are consistent with the conclusions of theoretical characteristics.
