摘　　要：本工作研究了BC电池与低铁镀膜玻璃透光率的匹配问题,探索了不同透光率和反射率镀膜玻璃对BC电池组件功率的影响。通过对比不同铁含量和反射率的镀膜玻璃封装的BC电池组件,发现全波段透光率的提升并不一定能带来组件功率的线性增长,而与电池光谱响应曲线相匹配的特定波段透光率优化更能有效提升组件功率。实验结果还表明,低反射率镀膜玻璃可以降低组件封装损失,提升组件功率。因此,在设计和制造低铁镀膜玻璃时,需要综合考虑透光率、反射率等光学特性,并与太阳电池的光谱响应特性进行匹配以实现光伏组件性能的最大化。In this work,the matching of BC cells with the transmittance of low-iron coated glass was investigated,and the effects of different transmittance and reflectance coated glass on the power of BC cell modules were explored.By comparing BC modules encapsulated with coated glass of different iron contents and reflectances,it is found that the enhancement of full-band transmittance does not necessarily lead to a linear increase in module power,while the optimization of specific band transmittance matching the spectral response curve of the cell is more effective in enhancing module power.The experimental results also show that low reflectivity coated glass can reduce module encapsulation loss and improve module power.Therefore,when designing and manufacturing low-iron coated glass,optical properties such as transmittance and reflectance need to be considered comprehensively and matched with the spectral response characteristics of the solar cell in order to maximize the performance of PV modules.
