招商证券主要观点如下: 浆料是电池制造的关键材料,影响电池效率表现 太阳能电池整体结构基于大面积的PN结,在光照条件下光生电子将通过印刷在电池表面的细栅、主栅 汇集,经由焊带至外电路对外做功,实现光能向电能的转化。电池片正背面栅线由浆料印刷制成,实现 电池片层级的汇流,按形态、功能分为细栅、主栅,其图形设计影响电池受光量,材料配方等影响复合 表现,决定其等效电阻,因而浆料对光伏电池光电转换效率及组件性能表现极为关键。 "银"大于"硅",降银提供最大的潜在降本空间 过去电池浆料以银体系为主,银价大幅上涨后,电池非硅成本中浆料占比跃升,以主流TOPCon电池为 例,单瓦成本由6分左右跃升至0.1-0.2元(考虑银价波动),已经超过硅料,成为电池成本第一大项,降银 单耗成为产业链降本的重点。 智通财经APP获悉,招商证券发布研报称,近年来银价持续上升,尤其2025年大涨后浆料成本占比已经 超过硅料,且银价大幅波动对产业链盈利影响巨大,贱金属替代更加迫切。结合产业反馈当前在粉体、 浆料、电池环节的深度合作下铜代银已取得积极进展,若顺利产业化各参与环节均有望获得丰厚回报, 同时考虑周期底部技术扩散节奏更慢,浆料技术变革 ...
光伏行业上市公司积极投身“反内卷”行动
