Paint and varnish are everywhere around us.

is also important to factor in the financiallysustainable aspect of surface treatment

New product….In three years, buildings covered in steel

sheets could be generating large amounts of solar electricity, thanks to a new photovoltaic

paint that is being developed in a commercialpartnership between UK universityresearchers and the steel industry.

These new solar cells also have theadvantage of being able to absorb across thevisible spectrum. That makes them moreefficient at capturing low radiation light thanconventional solar cells, and so well suited tothe British climate with its many cloudy days.
