This study presents new hole‐transport materials (HTMs) to replace the central spiro linkage in spiro ‐OMeTAD by a CC bond in H11 and CC double bond in H12 . This structural change results in a facile synthetic process and a significant change in the molecular geometry. Employing H11 as HTM in combination with mixed ion perovskite [HC(NH 2 ) 2 ] 0.85 (CH 3 NH 3 ) 0.15 Pb(I 0.85 Br 0.15 ) 3 , gives a solar cell power conversion efficiency of 19.8%.
