The main objective of the programme is to establish the scientific and technical basis for the application of ionic liquids (IL) in the low temperature electrodeposition of coatings for solar energy harvesting.

Spectrally selective coatings are important to enhance the efficiency of thermal solar energy conversion. Suitable coatings can be produced by electrodeposition from CrVI aqueous solutions, but the health and environmental impact of these solutions is extremely high. In the present programme cost effective and environmentally friendly deposition processes from CrIII ionic liquids solutions will be developed.

The coatings structure and properyies will be characterised by suitable methods. Their corrosion resistance will be evaluated by salt spray and electrochemical methods. Auger electron spectrometry and X-ray photoelectron spectrometry will be studied to study the coatings degradation when exposed to the atmosphere.
