PINA CREATION - Development of Printable Indium Tin OxideI(TO) Nano Inks for Low-Temperature Transparent Conductive Films

This work presents the development of printable Indium Tin Oxide (ITO) nano inks designed for low-temperature fabrication of transparent conductive films. Conventional ITO deposition relies on high-temperature and vacuum-based processes, limiting compatibility with flexible substrates and increasing manufacturing cost and energy consumption. In this study, we introduce a solution-processed ITO nano ink with controlled particle size, stable dispersion, and optimized rheology for scalable coating techniques such as spin coating and slot-die coating. The resulting films demonstrate high optical transparency, good electrical conductivity, and uniform morphology at processing temperatures below 150 °C. This approach enables a cost-effective and energy-efficient pathway for producing transparent conductive layers in next-generation electronics, including photovoltaics, displays, and printed devices
