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.carbyazolesthin-layer conductivityorganic hole transportersperovskite solar cellspower conversion efficiencytext::journal::journal article::research article
