Availability of indium tin oxide (ITO) is essential for the growth of the EU solar and electronics industries. Electronics industry uses LCD displays in many types of applications and equipment. On the other hand, solar industry uses ITO as a top electrode in solar cells. Nevertheless, automotive and aircraft windscreen glass industries use ITO as glass coating for de-misting and de-icing application. TCOs are the key components used for the construction of a variety of electronic devices. The most important technologies are liquid crystal displays (LCDs), capacitive touch screens and solar photovoltaic (PV) cells.

Every examined m-TCO will be subset of a binary oxides system such as SnO2-ZnO-Ga2O3. This oxide system is composed of group IIB, IVA and IIIA metals having relative small ions which are not as electropositive as the alkaline earth metals. AltiTude aims to combine these binary oxides, taking into account that they have been used individually in TCO manufacturing. Attention will be payed in focusing on the appropriate stoichiometry of state of the art binary oxides as well as modeling via computational estimation of their electronic structure and properties. In comparison with simple binary oxides, the multicomponent oxides are expected to give more freedom in tuning materials’ chemical and physical properties. By varying the relative binary oxide ratios the band gap energy will be enhanced. The m-TCOs will also show significantly reduced acid etching rate in contrast to precursor binary oxides. Additionally, the proposed raw materials are abundant, inexpensive and non-toxic in dissimilarity with ITO, moreover they will be chemically stable which is necessary properties for the fabrication of solar cell.
