Abstract

Abstract: The small‐molecule‐based hole‐transporting material methoxydiphenylamine‐substituted carbazole was synthesized and incorporated into a CH3 NH3 PbI3 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. Abstract : Quick and easy : The readily synthesized methoxydiphenylamine‐substituted carbazole (V886), a hole‐transporting material, has been used in perovskite solar cells with a power conversion efficiency of 17 %. This is the second highest conversion efficiency after that of solar cells with the hole transporter Spiro‐OMeTAD.
