ITO alternatives to gain speed in the USD2 Billion transparent conductive films market, says IDTechEx
July 04, 2012 // Cathleen Thiele, Technology Analyst, IDTechEx
Today, only one type of film - Indium Tin Oxide (ITO) - is used for almost all transparent conductive films with a market size of over $2 billion this year. It is entrenched in the display industry and will be hard to displace.
However, there is an interest to move away from this and there are now many alternative solutions emerging. These include finely printed conductive meshes, layers of silver or copper that are highly transparent, organic transparent conductors and variations such as carbon nanotubes and graphene. These solutions are discussed in the recently updated IDTechEx report Transparent Conductive Films 2012-2022.
The commonly used options (excluding uses of transparent conductors that are not in displays, photovoltaics or touchscreens) with their market share today is shown in this table:

Most of the focus is on use as a transparent conductor for display, solar and touchscreen applications - representing the biggest need and opportunity. This figure shows our forecast and outlines the market segments covered in our analysis.

In comparison to other types of transparent conductors ITO has a very competitive conductivity-transparency-ratio. However, an issue not only for ITO, but also many other types of TCF, is that they are not particularly flexible. Sputtered ITO and other TCO layers on plastic films are known to be brittle, and they crack upon a few percent strain.
As more and more flexible devices are required, the market for transparent conductive films increases. The trade-off between conductivity, transmittance, and flexibility is best met with materials other than the traditional conductive oxides, which are expected to get more expensive as in the case of ITO, and many companies and research institutes work on alternate technologies.All news
