Description We found what limits the conductivity of a transparent conducting oxide (TCO) material, fluorine-doped tin dioxide. TCOs are used for flat panel displays, low emissivity window coatings and thin film solar cells. We found a way to make transparent conducting oxides more conducting and more transparent, particularly in the infrared part of the spectrum. This will enable better solar cells to be made. It also has applications in displays, where the same performance will be possible using less indium, a scarce and expensive element.
Exploitation Route The results should enable more conducting films to made in the future with different dopants from fluorine.

Transparent conducting oxide films with improved infrared transparency will now be possible using our novel dopants and insights.
