摘要

In this study, poly(3,3-dibenzyl-3,4-dihydro-2 H -thieno[3,4- b ][1,4]dioxepine)/platinum composite films (PProDOT-Bz 2 /Pt) were used as counter electrodes (CEs) in dye-sensitized solar cells (DSSCs). The composite films were prepared on fluorine-doped tin oxide (FTO) glass by radio frequency (RF) sputtering to deposit platinum (Pt) for 30 s. Afterwards, PProDOT-Bz 2 was deposited on the Pt–FTO glass via electrochemical polymerization. The electron transfer process of DSSCs was investigated using electrochemical impedance spectroscopy (EIS) and cyclic voltammetry (CV). The DSSCs with 0.05 C/cm 2 PProDOT-Bz 2 -Pt composite films showed an open circuit voltage ( V oc ) of 0.70 V, a short-circuit current density ( J sc ) of 7.27 mA/cm 2 , and a fill factor (F.F.) of 68.74%. This corresponded to a photovoltaic conversion efficiency (η) of 3.50% under a light intensity of 100 mW/cm 2 .
