| Abstract [eng] |
We report the synthesis of three novel enamine hole-transporting materials (HTMs) based on Tröger's base scaffold. These compounds are obtained in a three-step facile synthesis from commercially available materials, without the need of expensive catalysts, inert conditions or time consuming purification steps. The best performing material, HTM3, demonstrated 18.62 % PCE in PSCs, rivaling Spiro-OMeTAD in efficiency, and showing markedly superior long-term stability in non-encapsulated devices. In dopant-free PSCs HTM3 outperformed Spiro-OMeTAD by 1.6 times. The high glass transition temperature (Tg = 176 °C) of HTM3 also suggests promising perspectives in device applications. © 2019 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. |
