由于水溶性铅的毒性，有机-无机铅卤化物钙钛矿太阳能电池（PSCs）的回收利用越来越受到人们的关注。在这里，我们报告了一个高度可靠的两步过程，回收成本占主导地位的氧化铟锡（ITO）基板涂有NiOx和再生的二烷基胺的功能，其基础的PSC。冠军回收PSC可以实现20%的转换效率，高于新鲜PSC的17.92%。MEW惊人的是，再生设备可以在10个周期的前7个周期内保持上级性能。综合X射线光电子能谱分析表明，二丙胺通过Ni-N配位与NiOx表面发生了合适的相互作用，使其有效的界面钝化和高质量钙钛矿生长的模板效应得以实现。这导致了抑制界面和体的非辐射复合，最终提高了器件的性能。二烷基胺驱动的两步回收工艺提供了一种有前途的和高度可重复的策略来回收PSC，特别是成本主导的NiOx/ITO基板。
Because of the toxicity of water-soluble lead, the recycling of organic-inorganic lead-halides perovskite solar cells (PSCs) has attracted increasing attention. Here, we report a highly reliable two-step process to recycle cost-dominated indium-tin-oxide (ITO) substrates coated with NiOx and regenerate their based PSCs by function of dialkylamines. The champion recycled PSC can achieve 20% in conversion-efficiency, higher than 17.92% of the fresh one. MEW Strikingly, the regenerated devices can remain superior to the fresh ones in the first 7 of 10 recycles. The comprehensive X-ray photoelectronic spectroscopy analysis reveals that dipropylamine has a suitable interaction with NiOx surfaces by Ni-N coordination, enabling its effective interfacial passivation and template effect of high-quality growth of perovskites. That leads to the suppressed nonradiative recombination of both interfacial and bulk, and finally improves the device performances. The dialkylamines driven two-step recycling process offers a promising and highly reproducible strategy to recycle PSCs, especially the cost-dominated NiOx/ITO substrates.
