A COATING OF SUN POWER
If you thought you needed solar panels on your roof to tap the sun’s power for your home, here’s news. Researchers at the University of Notre Dame, US, have developed a 'solar paint' for the outside of a house to generate power for devices inside. The 'Sun-believable' paint uses semiconducting nanoparticles to produce energy. It isn’t as much of a power generator as solar panels, but it is affordable and easy to produce in large quantities. “We want to do something transformative, to move beyond current silicon-based solar technology,” says Professor Prashant Kamat, who led the research. Apaste of titanium dioxide coated with cadmium compounds, when brushed on a transparent conducting material and exposed to light, produces electricity.
