Computational actuation on design of small-molecule triphenylamine derivative-based hole-transporting materials (HTMs) is a high-efficient way to acquire potential HTMs for perovskite solar cells (PSCs). In the work, on basis of...
Unreported 2,3-dicyano-fluoranthene was first prepared as an efficient electron-withdrawing building block for constructing D–A type dopant-free hole transporting materials.
One-pot synthesized low-cost HTM V1275 exhibits a remarkable performance of 19.3% in PSCs with exceptional stability retaining 125% of the original PCE after 500 h.
