Nano Structure TiO2 Films by Hybrid PEO-Hydrothermal Method for Dye Sensitised Solar Cell Applications, M.Sc. Thesis Sharif University of Technology ; Faghihi-Sani, Mohammad Ali (Supervisor) ; Mohammadpour, R (Co-Advisor)
Abstract
This thesis demonstrate a new hybrid Plasma Electrolytic Oxidation (PEO)-Hydrothermal method to produce a nano-structured TiO2 layer over a titanium substrate. Microstructural characterization was carried out by using a FE-SEM to explore nano scale structural changes due to hydrothermal treatment. More over EDS was used to analyse elements of the coating. The FE-SEM images confirmed formation of a 3D network consisting “nano flakes+nano fibers”after 6 or 12 hours and a ”sea urchin like nanostructure+nano fibers” after 24 hour. To improve the performance of nano-structured photoelectrodes, different electrolytes were studied to achieve maximum amount of anatase phase. the best results was...
