Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>The small‐molecule‐based hole‐transporting material methoxydiphenylamine‐substituted carbazole was synthesized and incorporated into a CH₃NH₃PbI₃ 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.</p> </abstract>
