Titanium dioxide nanoparticles coated with cadmium sulfide produced a yellow paste that, when painted onto a transparent conductive material, generates electricity (Photo: ACS Nano)
Mixtures using cadmium sulfide produced yellow paint, cadmium selenide produced dark brown, while a mixture of the two - which offered the best conversion efficiency - was light brown (Photo: ACS Nano)
A team of researchers from the University of Notre Dame in Indiana is reporting the creation of a "solar paint" that could mark an important milestone on the road to widespread implementation of renewable energy technology. Although the new material is still a long way off the conversion efficiencies of commercial silicon solar cells, the researchers say it is cheap to make and can be produced in large quantities.
