Description | ||||||
The TiO2 compact layers produced by the electrochemical deposition method were employed as blocking underlayer in dye-sensitized solar cells (DSSCs). The galvanostatic deposition method was utilized to deposit TiO2 compact layer (TiO2-CL) onto FTO substrates from acidic titanium (III) chloride electrolytic solution. The formation-TiO2 compact layers were affirmed by X-ray diffraction (XRD). The transparency of TiO2 compact layer was examined by UV-vis absorption spectroscopy. The present work mainly investigated the effect of TiO2-CL incorporation on the photovoltaic performance of the DSSCs where the photosensitizer is LEG4 organic dye and the redox mediator is CoII/CoIII based electrolyte. Incorporation of TiO2-CL between transparent FTO electrode and meso-TiO2 could increase efficiency of a device with an obvious increase in short circuit current density. The power conversion efficiency is 4.3% and 3.5% of the devices with and without TiO2-CL. | ||||||
