Two carbazole‐based small molecule hole‐transport materials (HTMs) are synthesized and investigated in solid‐state dye‐sensitized solar cells (ssDSCs) and perovskite solar cells (PSCs). The HTM X51‐based devices exhibit high power conversion efficiencies (PCEs) of 6.0% and 9.8% in ssDSCs and PSCs, respectively. These results are superior or comparable to those of 5.5% and 10.2%, respectively, obtained for the analogous cells using the state‐of‐the‐art HTM Spiro‐OMeTAD.
