Dopant-free hydrophobic fluorene-based hole transport materials: impact of methoxy-substituted triphenylamine and carbazole peripheral groups on the performance of perovskite solar cells
Two fluorene-based dopant-free D–π–D type HTMs (V1 and V2) are designed. The perovskite solar cell with V1, which contains a methoxy-TPA donor moiety, achieves a PCE of 14% maintaining 75% of its initial efficiency for over 480 hours.
