Poly[bis(4-phenyl)(2,4,6-trimethylphenyl)amine] (PTAA), as an extensively used hole transport material in inverted perovskite solar cells (PSCs), has given reason for concern due to its hydrophobicity for a long time. Herein, buried interface engineering is applied for the scalable deposition of perovskite films by introducing an amphiphilic molecule hexadecyltrimethylammonium chloride on the PTAA surface, which improves the interfacial wettability of the perovskite precursor solution on the organic hole transport layer (HTL), facilitates the nucleation and growth of perovskites, and reduces the nonradiative recombination at the perovskite/HTL interface. As a result, all photovoltaic parameters of the inverted PSCs are improved significantly. The champion devices demonstrate power conversion efficiencies (PCEs) of 22.04% and 20.47% with aperture areas of 0.148 and 1.0 cm², respectively. Moreover, the encapsulated 1.0 cm² device exhibits excellent stability and maintains over 70% of its initial PCE after 1200 h under continuous 1 sun illumination at 65 °C in a nitrogen environment.

埋入界面工程实现高效、可扩展且稳定的倒置钙钛矿太阳能电池

聚[双(4-苯基)(2,4,6-三甲基苯基)胺](PTAA)作为倒置钙钛矿太阳能电池(PSC)中广泛使用的空穴传输材料，由于其疏水性而引起人们的关注。很久。在此，埋入界面工程通过在PTAA表面引入两亲性分子十六烷基三甲基氯化铵，应用于钙钛矿薄膜的可扩展沉积，从而提高了钙钛矿前驱体溶液在有机空穴传输层（HTL）上的界面润湿性，促进成核和沉积。钙钛矿的生长，并减少钙钛矿/HTL界面处的非辐射复合。结果，倒置PSC的所有光伏参数均得到显着改善。冠军器件的功率转换效率 (PCE) 分别为 22.04% 和 20。^分别为2。此外，封装的1.0 cm ²器件表现出优异的稳定性，在氮气环境中65°C连续1太阳光照下1200小时后仍保持其初始PCE的70%以上。
