摘要
本工作研究了提升背接触(BC)电池组件功率的关键路径——光学性能优化,通过材料选择和设计的优化为BC电池组件的性能提升开辟了新的方向。首先揭示了新型绒面BC电池的潜力,即显著降低了反射损失,为效率提升奠定了基础;其次聚焦于短波优化共挤胶膜,通过调整其透光率曲线与BC电池的光谱响应相匹配,进一步挖掘了效率提升的空间;最后试验验证了新型绒面BC电池与短波优化共挤胶膜的协同效应,展示了其对组件光学性能和转换效率的显著提升。
This work studied the key path for improving the power of BC battery modules-optical performance optimization,aiming at opening up a new direction for enhancing the performance of BC battery modules through the optimization of material selection and design.It first revealed the potential of the new textured BC battery,which significantly reduced reflection loss and layed the foundation for efficiency improvement.It then focused on the short-wave optimized co-extruded adhesive film and adjusted its light transmittance curve to match the spectral response of the BC battery,thereby further exploring the room for efficiency improvement.Finally it experimentally verified the synergistic effect between the new textured BC battery and the short-wave optimized co-extruded adhesive film,demonstrating that the strong combination of the two brings significant improvements to the optical performance and conversion efficiency of the module.
