| Abstract Scope |
Transparent conducting films are optically transparent and electrically conductive material, typically used as electrodes in photovoltaics that call for low resistance electrical contacts without blocking the incident light. Indium tin oxide (ITO) is the most widely used owing to its excellent optoelectronic properties and ease of deposition. Solution processing is a cost-effective approach to deposit films under ambient conditions with minimum material wastage. In this research, ITO films were deposited on soda-lime glass substrates using a sol-gel ink through spin coating.
Different conditions of deposition humidity were evaluated, and the results were optimized to achieve the best electrical properties while maintaining high optical transparency and uniform surface morphology. It was observed that high humidity values affect the substrate wetting property of the ITO ink and increase the possibility of hydrolysis during deposition, resulting in
the formation of non-uniform surface patterns. |
