摘要
设计一种表面压花的光伏玻璃以减少太阳电池细栅遮挡。该光伏玻璃设计可适应入射角变化范围为0°~23.5°的情况,为无太阳追踪功能的太阳电池实现减少细栅栅线遮挡效果提供解决方案。对一种栅线设计情况下的光伏玻璃压花设计、厚度要求进行探讨,并采用TracePro软件对减遮挡效果进行光学仿真实验。针对光学仿真实验中光强分布情况,从功率损失和串联电阻2个方面分析新型光伏玻璃对太阳电池效率的影响。分析结果显示,新型光伏玻璃可将太阳电池转换效率提升0.20%-0.35%。
A surface patterned photovoltaic glass(PV glass)is designed to reduce the solar cell finger grid shadowing loss.This photovoltaic glass design can adapt to the incident angle variation range from 0°to 23.5°,which can provide a solution for reducing the finger grid shadowing loss effect for solar cells without solar tracking.In this paper,the patterned photovoltaic glass design and the thickness requirements were being discussed,and the optical simulation experiment was also carried out by using TracePro software to reduce the shadowing loss effect.Meanwhile,according to the distribution of light intensity in optical simulation experiments,the influence of this new photovoltaic glass on solar cell efficiency were also analyzed from two aspects:power loss and series resistance,and it shows that solar cell efficiency can be increased by 0.2%-0.35%.
