Abstract:
A series of spiro‐arranged hole‐transporting materials are designed and synthesized by incorporating a substituted phenylpyrazole unit to the orthogonal dibenzosuberene core unit, which are named as THY‐1 to THY‐5. All of them exhibit good optical, electrochemical, and electronic properties as needed for HTMs, despite the distinctive morphologies observed for the spin‐casted thin film. A perovskite solar cell based on THY‐5 exhibits the highest power conversion efficiency of 15.83%, which is comparable to that of the N2,N2,N2′,N2′,N7,N7,N7′,N7′‐octakis(4‐methoxyphenyl)‐9,9′‐spirobi[9H‐fluorene]‐2,2′,7,7′‐tetramine (Spiro‐OMeTAD) reference device (16.22%) fabricated using identical architecture.
