Vital Materials is a global company providing materials across many industries including displays, photovoltaics, semiconductors etc. We provide materials such as metals, ceramics, semiconductors, and transparent conductive oxides. Vital is the single largest manufacturer of ITO targets. As the photovoltaic industry moves towards higher efficiencies and low cost processes, this requires innovation of novel transparent conductive oxides that can be processed at low temperatures while maintaining low sheet resistance and high transmission. Having good broadband transmission across the 300-1200nm while maintaining low resistance values would be an added value. Traditional ITO requires high processing temperatures to achieve low resistance. However low resistance also results in lower transmission above 800nm. Vital Materials has been working towards development of such transparent conductive oxides one of which is LTC V2. This presentation will cover comparison of traditional ITO film properties to a new novel material LTC V2 that provides low resistance combined with high transmission across the 300-1200nm wavelength range.
