钙钛矿电池效率世界纪录再度刷新。近日,经国家光伏产业计量测试中心认证,脉络能源研发的钙钛矿室内光伏电池光电转换效率在1000lux U30光源照射下达到44.72%,为当前世界最高值。
据悉这是继2022年获得大面积柔性钙钛矿室内光伏组件孔径面积效率29.69%、刚性室内光伏组件34.94%(有效面积效率36%)的世界最高认证效率之后的又一突破。
据《科创板日报》不完全统计,A股中已布局钙钛矿的公司包括:

但值得注意的是,虽说钙钛矿理论效率及理论成本优势明显,但仍有多个核心瓶颈亟待解决,包括:
产业化膜层均匀性难以保证、电池死区不可避免,导致大面积制备的钙钛矿效率损失严重;同时,离子键结构的钙钛矿溶液易分解、对外界干扰敏感,钙钛矿电池/组件容易衰减,产品寿命远弱于晶硅电池。
设备厂商科恒股份此前也提醒,因钙钛矿型太阳能电池属于新的太阳能技术,目前该技术尚处于研发之中,尚未形成完全成熟的生产工艺,该技术是否能够获得突破形成规模应用和何时形成规模应用尚存在重大不确定性。
