Abstract :The discovery of transparent conducting oxides, TCO’s, has been a major breakthrough across electro-optical industries as significant durability, portability and flexibility of products have been achieved without compromising the efficiency and cost effectiveness of such product. Indium tin oxide, ITO, being the most widely used has shown appreciable performance with its high transmittance range of values coupled with high conductivity. Its toxic nature and continuous scarcity in the earth crust has however raised a concern, thereby necessitating an urgent need for adequate and effectual alternatives. With some of these alternatives already in use, the method applied in the preparation of TCO thin film is another factor that affects its performance. Sol-gel spin-coating method being one of the many deposition methods available is of great importance due to its simplicity and relatively low cost. This study therefore, seek to appraise the performance of aluminium-doped tin oxide insert ignore into journalissuearticles values(ATO);, fluorine-doped tin oxide insert ignore into journalissuearticles values(FTO); and aluminium-doped zinc oxide insert ignore into journalissuearticles values(AZO); as sustainable alternatives to ITO with focus on spin-coated thin film.
