隆基绿能获专利，异质结电池在硅片中央与边缘采用不同硅材料

11月6日，隆基绿能（601012）的发明专利《异质结太阳能电池及其制备方法》获授权，申请号为CN202410317992.4。

这项方案没有把整片掺杂层处理成同一种结构。硅片两面先设置本征非晶硅膜，然后把掺杂层中部转化为微晶硅，环绕硅片的外缘仍保留非晶结构。正面与背面分别采用N型和P型掺杂。按专利描述，这样既可以沿用非晶硅较快的沉积过程，又能在中部利用微晶硅的电学特性。工艺变化集中在材料如何分区和晶化。

截至此次授权消息披露时，隆基绿能今年获得的各类专利授权共180项，比上年同期减少43.04%。在2026年上半年，公司研发投入为7.89亿元，同比增长5%。企业知识产权记录中，隆基绿能科技股份有限公司名下可查到2497条专利信息和45条著作权信息。
