Description
技术领域
本发明属于太阳能电池技术领域,具体涉及一种用于提高反向钙钛矿太阳能电池稳定性的电子传输层及制备方法。
背景技术
太阳能作为一种理论意义上取之不尽用之不竭且绿色无污染的清洁能源受到人们的青睐,太阳能电池是将太阳能转换为电能的重要器件。这其中,钙钛矿太阳能电池自从2009年问世,经过十年的发展,效率已经突破23%,取得了其他种类电池所没有的佳绩,但是钙钛矿太阳能电池的稳定性,尤其是钙钛矿材料的湿气稳定性,严重阻碍了其商业化的脚步。因此,研究制备既能有效传输电荷又能抵御水汽侵蚀的材料以推动钙钛矿太阳能电池发展具有重要意义。
为了有效解决水(气态水和液态水)对钙钛矿太阳能电池的影响,专利CN106340590B在反向钙钛矿太阳能电池电子传输层中引入聚四氟乙烯作为疏水材料,能够有效提高钙钛矿太阳能电池的稳定性。专利CN207572403U在钙钛矿太阳能电池吸光层表面加了一层紫外疏水层,该层一方面具有防潮保护作用,防止钙钛矿吸光层水解,另一方面,可以吸收紫外光,防止钙钛矿吸光层光解,因此可以有效提高钙钛矿太阳能电池的稳定性。但现有的改善钙钛矿太阳能电池稳定性的方法主要是通过对太阳能电池用疏水性材料进行封装等方法,而没有从提高电子传输层或空穴传输层的疏水性方面进行。
发明内容
