The availability of low-cost hole transport materials (HTMs) that are easy to process is crucial for the eventual commercialization of perovskite solar cells (PSCs), as the commonly used HTM (Spiro-OmeTAD) is expensive, and its processing is complex. In this study, we synthesized an amorphous molecular material (termed as TPA-glass) from the condensation of 2-mexylamino-4-methylamino-6-(4-aminophenylamino)-1,3,5-triazine and N-(4-formylphenyl)diphenylamine with a low-cost and easy process, and applied as an HTM in PSCs. We investigated the effect of TPA-glass thin-films with varying thickness, as well as their corresponding solar cell’s properties. The preliminary performance data indicate that TPA-glass thin-film can be a potential HTM candidate for planar PSCs.

易于加工的低成本空穴传输材料 (HTM) 的可用性对于钙钛矿太阳能电池 (PSC) 的最终商业化至关重要，因为常用的 HTM (Spiro-OmeTAD) 价格昂贵且加工复杂。在这项研究中，我们从 2-mexylamino-4-methylamino-6-(4-aminophenylamino)-1,3,5-triazine 和 N-(4-甲酰基苯基）二苯胺具有低成本和简单的工艺，并在 PSC 中用作 HTM。我们研究了不同厚度的 TPA 玻璃薄膜的影响，以及它们相应的太阳能电池的特性。初步性能数据表明 TPA 玻璃薄膜可以成为平面 PSC 的潜在 HTM 候选者。
