AltiTude project group has identified an opportunity to develop alternative multicomponent transparent conductive oxide systems (m-TCOs), that will exhibit unique properties by using appropriate combinations of low-cost raw materials, suitable for large scale manufacturing of transparent conductors (TCs). This project is aiming in the replacement of the commonly used but expensive indium tin oxide (ITO) via innovative RTD and thus to achieve substantial financial returns. ITO is considered as the de facto TCO without which the manufacturing of displays (e.g. LCD televisions and smart phone touch screens), solar photovoltaic (PV) cells (e.g. thin film and traditional silicon) and automotive or aircraft conductive glass would not be possible. ITO is a scarce and thus expensive material as its major constituent is indium. Consequently, the use of ITO is not sustainable due to its high indium content (above 72 wt.%). The increasing use of ITO is endangered by the scarcity and high price of indium. A variety of alternative ITOs have been proposed the recent years having limitations in their use taking into account that some of the raw materials used in this alternative TCO are toxic.
AltiTude project focuses on developing its core business via innovative RTD in:
- Modeling and design of advanced m-TCO material expiring excellent optical and electrical properties comparable to ITO. This could be achieved by optimizing the suitable stoichiometry’s of the selected binary oxides as well as by modeling and predicting the desirable properties.
- Development and implementation of a “Green Dry Route” (GDR) metal atomisation and direct oxidation technique via the creation of a low-cost procedure for the synthesis of m-TCO powders.
- Use of “super-activation” via a hyper-energy milling technique leading to the m-TCOs targets, in terms of reducing the particles size resulting to high quality sputtering targets and lower temperature technique.
