天合光能获专利,太阳能电池绒面凹槽采用弧形过渡

11月6日,天合光能(688599)的发明专利《用于太阳能电池板的绒面结构层和太阳能电池》获授权,申请号为CN202411250299.6。

方案关注的是光伏电池表面微小凹陷的几何形状。每处凹陷都有开口、侧壁和底面,靠近底部的一段侧壁设计成曲面,让它与底面平滑相接。这种局部结构可作为绒面层用于电池,并进一步用于光伏组件及系统。专利把短路电流、填充因子和光电转换效率列为希望改善的性能指标,公开摘要没有给出具体提升百分比。

截至此次授权消息披露时,天合光能今年获得的各类专利授权共389项,比上年同期减少24.32%。在2026年上半年,公司研发投入为10.21亿元,同比增长13.44%。企业知识产权记录中,天合光能股份有限公司名下可查到4896条专利信息和131条著作权信息。
