Comparative study between dye-synthesized solar cells prepared by electrophoretic and doctor blade techniques

Comparative study between solar cell sensitized by several naturel dyes and fabricated with two methods: electrophoretic deposition process (EPD) and doctor blade technique (DB) have been presented.TiO2 layers have been deposited on the glass FTO (Fluorine doped tin oxide: SnO2: F) for the tow techniques. Structural and morphological properties were presented and correlated to deposition conditions of growing films. Natural dyes have been prepared and used to realize Dye-Synthetized Solar cells (DSSCs).Developed electrical model was used to study and extract experimental parameters. The compared I – V measurements under 100 mW/cm2 illumination have shown an increase in both filling factor (FF) to reach 58.85% and open circuit voltage (Voc) value of 0.66 V for mallow sensitized solar cell fabricated with EDP technique. A decrease in short circuit current (Isc) and efficiency (η) due to the TiO2 layer thickness and the cracks appearing in the layer fabricated with EPD technique.
