DYE-SENSITIED SOLAR CELL ASED ON TiO2-MgO COMPOSITE ELECTRODES Y USING COMINED DYE
Abstract
- This research focused on improving the methodology of producing dye-sensitized solar cell (DSSCs) by the process of amalgamation with natural dyes. In this research, the ss dye as chlorophyll and yellow dye as anthocyanian have been prepared and mixed these dyes. The combination of natural dyes by the ratio (1:1) used in the DSSCs as sensitizer. Next the titanium dioxide (TiO2) and magnesium oxide (MgO) composite materials were mechanochemically prepared. And TiO2 and MgO were mixed in different ratios as TiO2 (pure), TiO2 (95%)MgO(5%) and TiO2(90%)-MgO(10%). Then, the TiO2 – MgO powder were prepared to be paste and they were deposited onto ITO/glass substrate by rolling method and immersed in the mixed dye solution to get dye cells. The dyed TiO2-MgO-ITO/glass cells were offset with ITO/glass cell coated with adhesive carbon paste. The photovoltaic properties of prepared TiO2-MgO DSSCs were investigated by J-V measurements. The results showed that the efficiency and fill factor (FF) were acceptable for industrial requirement and they are inexpensive candidates for DSSCs fabrication.
