The small‐molecule‐based hole‐transporting material methoxydiphenylamine‐substituted carbazole was synthesized and incorporated into a CH 3 NH 3 PbI 3 perovskite solar cell, which displayed a power conversion efficiency of 16.91 %, the second highest conversion efficiency after that of Spiro‐OMeTAD. The investigated hole‐transporting material was synthesized in two steps from commercially available and relatively inexpensive starting reagents. Various electro‐optical measurements (UV/Vis, IV, thin‐film conductivity, hole mobility, DSC, TGA, ionization potential) have been carried out to characterize the new hole‐transporting material.
