光伏电池降本新突破!可节省高达12%的白银成本

幻启太阳能科技 11/29/2021

  11月17日,美国专利商标局宣布授予光伏制造商Solar Inventions光伏电池改进架构的专利,据了解,该发明可节省高达12%的白银成本。

  《全球光伏》获悉,该发明被称为可配置电流电池或C3,可节省高达12%的白银成本,以目前的白银价格计算,相当于每吉瓦可节省100多万美元。

  为实现商业化,Solar Inventions利用该项技术建设了多个中试电池和组件产线,并获得了CFV、NREL和Sandia国家验室的独立第三方认证测试。经测试,C3技术可有效节省单晶PERC对银的使用量,并可应用于HJT、半片和双面组件。改进后的电池和组件可以在现有的光伏工厂生产线上生产,无需任何新的设备或材料。

  Solar Inventions CTO Damiani博士介绍,采用C3技术的PERC电池产线每吉瓦的产量可节省约100万美元的银,同时每块组件可提高2-3W的功率增益,从而获得价值100-200万美元的额外电力收益。由于光伏行业每年生产近200 GW的光伏电池,C3每年在全行业的影响可能达到4-6亿美元。?

  光伏电池使用正面银浆、背面银浆和背面铝浆三种导体浆料制两端电极,正面银浆是光伏电池受光面电极,直接影响着电池的光电性能,由高纯度的银粉、玻璃氧化物、有机树脂溶剂组成,其中玻璃氧化物等混合有机溶剂与加工成本占比不足5%,银粉用量占总成本的95%,因此直接决定了光伏电池的总成本。

  据介绍,随着美国专利第11,145,774号的到位,Solar Inventions 将在中国、欧洲和其它更多地区完成待决的C3专利,这些专利将占全球光伏市场的90%。
