雾霾天气对聚光砷化镓电池输出特性的影响
|
摘要
通过单块电池在实际天气下的实验测试了砷化镓聚光电池的输出特性,并对非聚光条件下不同辐照对电池输出的影响进行了分析。测试了电路负载对输出特性的影响,并据此确定了测试时系统的电阻。基于菲涅耳透射式聚光器和砷化镓高聚光电池构成的太阳能发电系统,对晴朗和轻微雾霾天气下电量输出特性进行测试,实验结果表明:随着辐照值的下降和透射式菲涅耳聚光器入射角的倾斜,发电功率迅速降低。轻微雾霾天气下,最大辐照只比晴天减小17%,但是最大发电功率却减小56%。
The output characteristics of Ga As concentrator battery was tested by actual weather experimental. Under non-condensing conditions, the influence of different radiation on the battery output was analyzed. The output characteristic with different loads was tested, and the resistance of test system was selected. Based on the power generation system composed by Fresnel transmissive concentrator and gallium arsenide high-concentration solar cell, the output characteristics of electricity in sunny and slight haze weather were tested. The experimental results show that with the decrease of irradiance value and inclination of Fresnel condenser incident angle, the power generation power rapidly reduces. Under slight haze weather, the maximum irradiance is only 17% less than that of the clear day, but the maximum power generation power reduces by 56%.
