Effect of Thiophene Insertion on X-Shaped Anthracene-Based Hole-Transporting Materials in Perovskite Solar Cells.

In this work, two novel tetra-substituted -shaped molecules and that were constructed with anthracene as the central core and arylamine as the donor groups have been synthesized. The HTMs and were synthesized in two steps from industrially accessible and moderately reasonable beginning reagents. These new HTMs are described in terms of utilization of light absorption, energy level, thermal properties, hole mobility (µ), and film-forming property. The photovoltaic performances of these HTMs were effectively assessed in perovskite solar cells (PSCs). The devices based on these HTMs accomplished an overall efficiency of 16.10% for and 10.25% for under standard conditions (AM 1.5 G and 100 mW cm). This precise investigation provides another perspective on the use of HTMs in PSCs with various device configurations.
