Kela Materials presents Strontium Vanadate (SrVO₄), a new-generation transparent conductive material considered a promising alternative to indium tin oxide (ITO). ITO has dominated transparent conductive films for over 60 years, but indium prices continue to rise, making cost and supply increasingly challenging for display and semiconductor industries.
SrVO₄ offers high visible-light transparency while providing good electrical conductivity and stability, making it a strong candidate for next-generation display materials, optoelectronic devices and transparent electronic components. Since 2015, multiple international research groups have identified SrVO₄-based systems as potential substitutes for ITO due to their lower cost, easier processing and excellent optical–electrical performance.
