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(NH₂)₂]_0.85(CH₃NH₃)_0.15Pb(I_0.85Br_0.15)₃, gives a solar cell power conversion efficiency of 19.8%.
