Abstract

Abstract: A molecular organic conductor was synthesized and used as electrolyte material, which can provide dual channels for triiodide/hole transportation in solid state dye sensitized solar cells. The introduction of additives into this electrolyte system further improved device performance. Electrochemical impedance spectrum revealed that a small quantity of antimony salt (N(PhBr)3 SbCl6 ) or iodine improved remarkably the charge transfer at the TiO2 /dye/electrolyte interface. Incident photon‐to‐current conversion efficiency also confirmed the positive effects of additives on the photoelectrical performance in this electrolyte system. Abstract : A molecular organic conductor TPA−Py‐I was synthesized and used as electrolyte material, which can provide dual channels for triiodide/hole transportation in solid state dye sensitized solar cells. The introduction of a small quantity of antimony salt (N(PhBr)3 SbCl6 ) into this electrolyte system further improved remarkably device performance, while not much has change for the " hole only" counterpart TPA−Py‐Cl electrolyte system.
