Small molecules based on N‐atom‐linked phenylcarbazole‐fluorene as the main scaffold, end‐capped with spirobifluorene derivatives, are developed as organic hole‐transporting materials for highly efficient perovskite solar cells (PSCs) and bulk heterojunction (BHJ) inverted organic solar cells (IOSCs). The CzPAF‐SBF‐based devices show remarkable device performance with excellent long‐term stability in PSCs and BHJ IOSCs with a maximum PCE of 17.21% and 7.93%, respectively.
