ITO（酸化インジウムスズ）の将来：透明導電体とITO代替材料の市場

Abstract

Indium Tin Oxide (ITO) is the most widely used transparent conductor in the display industry and also finds applications in photovoltaics, EL lighting and a variety of other optical and electronic applications. Yet, ITO has been described as the material that we love to hate," and for good reason. ITO is expensive. Indium is in short supply. And ITO is not well suited flexible substrates; the direction in which most display manufacturers are headed.

This report examines the opportunities for both improved formulations of ITO - especially ITO inks - and for ITO replacements. It covers ITO inks and hybrid materials that combine ITO with some other material. It also examines complete alternatives to ITO including PEDOT, other metal oxides and nanomaterials. Both currently available products and materials beginning to emerge from the labs are considered. In addition to analyzing the markets for alternatives to "ITO classic," this report also discusses the marketing issues that will have to be addressed to enable growth in these markets. The report includes an eight-year forecast of novel ITO formulations and alternatives. It also profiles the activities of leading companies and labs working in this field.
