(原标题:沈文忠:晶硅电池技术仍有很长的生命周期) 21世纪经济报道记者 曹恩惠、实习生余名伟 成都报道 11月19日,由南方财经全媒体集团指导、21世纪经济报道主办、中国国际光伏与储能产业大会组委会支 持的2025第八届中国国际光伏与储能产业大会暨21世纪·新能新质绿色能源发展论坛在成都隆重召开。 最后,提及钙钛矿技术,沈文忠认为单结钙钛矿是没有竞争力的,与晶硅电池叠层是必由之路。 沈文忠进一步围绕晶硅技术的不可替代性、非银金属化突破方向,以及TOPCon、BC、异质结三大主流 电池技术的竞争与协同,为"十五五"及更长周期光伏产业技术方向的发展提供了思考路径。 沈文忠指出:"晶硅的优势是非常明显的,未来十年,乃至更长时间内,我们看不到比晶硅更好的技 术。" 目前,光伏若要继续维持成本优势,需要进一步聚焦晶硅技术的优化。沈文忠介绍,目前,我国已全面 掌握硅提纯技术,硅料产能超300万吨,目前晶硅电池市场占比98%,是维持光伏低价的核心技术载 体。"但在当前晶硅电池成本中,银金属化占比极高,银价直接影响光伏的成本优势,所以未来五年一 定是无银化、贱金属化,金属化的铜、铝、镍等是一个发展趋势。" 沈文忠特别指出, ...

上海交大沈文忠: 相关部门正在制定光伏组件标准,标准是功率大小
Jing Ji Guan Cha Bao· 2025-11-19 10:59
"光伏行业肯定要淘汰一定的落后产能,在组件、电池端,主要参考指标是同样版型上的功率。"上海交 通大学教授、上海交通大学太阳能研究所所长沈文忠于11月18日在第八届中国国际光伏与储能产业大会 上接受经济观察报等媒体采访时表示。 "光伏组件、电池企业,尤其是TOPCon企业,面临着在未来一到两年内,是满足标准还是被淘汰的问 题。"沈文忠说。 TOPCon产能是光伏行业最为过剩的产能。目前全行业内有800GW(吉瓦)—1000GW产能,全年需求 约400GW。 沈文忠明确表示,未来将淘汰一半的TOPCon产能。 "一年多以来,光伏行业的技术创新非常多,目的就是为了提升功率,提升光电转换效率。"沈文忠说。 功率是光伏电池和组件的重要参数,一般而言,功率越高,光伏板发电量越多。 沈文忠表示,相关部门正在制定光伏组件标准,按照功率大小分为三个等级,划定的等级将成为国央企 招投标采购的重要标准。 今年9月11日,国家市场监督管理总局、国家标准化管理委员会发布《晶硅光伏组件和逆变器能效限定 值及能效等级(征求意见稿)》,其中规定拟将光伏组件按照技术路线分为TOPCon(隧穿氧化层钝化 接触电池)、BC(背接触电池)和HJT( ...
