Abstract:
Dye-sensitized solar cells were fabricated using MnO2 TiO2 electrodes, which were synthesized via sol-gel methods. The amount of MnO2 added to TiO2 sol was varied at 0, 0.1, 0.5, 1.0, and 3.0 percent wt. The mixed oxide sol was sprayed onto the fluorine-doped tin oxide glass substrates, followed by calcination at 400 Celsius degrees for two hours. The DSSCs was assembled as a sandwich-type cell by placing a MnO2 TiO2 thin film electrode on the top of platinum film counter electrode, separated by a sealing film with a thickness of 25 Mircro m. in the middle. The ruthenium-based dye used was N719 dye and the electrolyte solution composed of lithium iodide (LiI), iodine (I2), and 4-tert-butylpyridine in acetonitrile. The performance of DSSCs was measured using an IV tester under a 50W daylight LED illumination with a light irradiance of 15 mW per cm2. The power conversion efficiency of pure TiO2 electrode was 3.12 0.32 percent. The DSSCs with 0.5 percent wt. MnO2 TiO2 electrode exhibited an increase in cell efficiency to 4.83 0.36 percent. Moreover, both short circuit current density and open circuit voltage were improved with the greater amount of dye molecules adsorbed on the electrode as a result of larger specific surface area
