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.
