      abstract     = {Perovskite solar cells (PSCs) have recently achieved over
                      $26 \%$ power conversion efficiency, challenging the
                      dominance of silicon-based alternatives. This progress is
                      significantly driven by innovations in hole transport
                      materials (HTMs), which notably influence the efficiency and
                      stability of PSCs. However, conventional organic HTMs like
                      Spiro-OMeTAD and PTAA, although highly efficient, suffer
                      from thermal degradation, moisture ingress, and high cost.
                      This study explores the potential of iminodibenzyl, a moiety
                      known for its strong electron-donating capabilities in
                      pharmaceutical applications, as a novel HTM. A series of
                      fluorene-based derivatives incorporating iminodibenzyl
                      (TMF-2 and TDF-2) and diphenylamine (TMF-1 and TDF-1) units
                      were synthesized and characterized. The new HTMs
                      demonstrated commendable optical, electrochemical, and
                      thermal properties, as well as enhanced photostability.
                      Among them, TDF-2 achieved a power conversion efficiency
                      (PCE) of $19.38 \%,$ the highest of the new materials.
                      Although these efficiencies are slightly lower than the
                      benchmark PTAA $(20.20 \%),$ the study underscores the
                      potential of iminodibenzyl to enhance photostability and
                      increase HOMO levels, making it a promising candidate for
                      future HTM development in PSCs.},
