Abstract The availability of low-cost hole transport materials (HTMs) that are easy to process is crucial for the eventual commercialization perovskite solar cells (PSCs), as commonly used HTM (Spiro-OmeTAD) expensive, and its processing complex. In this study, we synthesized an amorphous molecular material (termed TPA-glass) from condensation 2-mexylamino-4-methylamino-6-(4-aminophenylamino)-1...
