| Abstract | ||
| In this study a classical conducting glass substrate was replaced by carbon steel substrate as working electrode (anode) in dye-sensitized solar cell. Cyclic voltammetry has been used to electro deposition 1 cm2 of conducting poly aniline on the surface of carbon steel substrate. Nano porous MgO oxide powder was prepared by sol-gel technique which has particle size about 28 nm. The nano powder was spread on the surface of conducting polymer to be used as PANI nano- oxide photo electrode in dye-sensitized solar cell and immersed in solution of methylene blue in water for 24 h at room temperature in the dark to be used for assembling of the DSSCs.The counter electrode is placed on top of metal oxide electrode, and then the two electrodes fastened to gather with two binder clips. The redox electrolyte solution containing 0.05M KI, and 0.05M I2 in acetonitrile is injected in between the dye coated metal oxide electrode and the counter electrode. This cell was gave efficiency 0.0135%. The catalytic activity of cell toward the electrolyte was studded by cyclic voltammetry. | ||
