CarboFilm

Solar cells and displays require electrode materials that combine a high level of electrical conductivity with the greatest possible transparency. Doped metal oxide films, which frequently are based on the rare element indium, have dominated this market for the past forty years. Since this market is expanding heavily among growing requirements for additional flexibility and costeffective, simple manufacturing methods, alternative materials are urgently needed. The objective of CarboFilm is to develop a novel composite material that combines the benefits of CNT with regard to flexibility, elasticity, and cost with the high conductivity and transparency of conductive oxides such as doped ZnO or SnO2 or conductive polymers. As an additional advantage, the innovative composite material can even be applied to flexible substrates at low temperatures with imprinting or roll-to-roll techniques, which allows for further simplification of production processes.
