New ‘green antenna’ could double solar power efficiency

Although the rise in solar power use has been both steady and promising, innovation and improvements in cell efficiency could make things even better. A new type of antenna has now been developed which could enable solar panels to become twice as efficient as those currently in operation, thereby increasing the deployment of rooftop solar cells.
The new ‘green antenna’ has been developed by a group of scientists from the University of Connecticut in the US. It collects much more of the blue part of the light spectrum (blue photons) than existing silicon solar panels, which convert light from around 600 to 1,000 nanometers (nm) into electricity but not from the 350 to 600 nm range.
