Direct C-H arylation coupling reaction has gained significant importance in synthesis of conjugated polymers for organic electronic applications. We report here a facile and straightforward method called “direct C-H arylation” reaction to synthesize conjugated 3,4-dioxythiophene and 1,4-dialkoxybenzene based copolymers as hole transport material (HTM) for perovskite solar cells. Two electron-rich conjugated polymers P1-2 were synthesized, in which 1,4-dibromo-2,5-bis(dodecyloxy)benzene and 3,4-dialkoxy-thiophene units were used for polymerization The resulting polymers were characterized and exhibited high solubility in organic solvents. Electrochem. and optical characterizations were carried out by cyclic voltammetry and UV-Vis-NIR absorption spectroscopy and found that these polymers show higher-lying HOMO energy levels with wide band gap. D. functional theory calculation was performed on these polymers (P 1-2) and correlated with our exptl. results. Finally, perovskite solar cells were fabricated by solution-processable deposition of P1-2 as dopant-free HTM with device geometry ITO/SnO2/Perovskite/HTM(P1/P2)/Ag and achieved a maximum power conversion efficiency of 5.28%. This study provides information on designing and simple preparation by direct C-H arylation reaction of higher-lying HOMO energy level polymer as HTM for perovskite solar cells.
