An Australian researcher has discovered a new method for harvesting solar power. Find out more about it, here's an excerpt:
Researchers for the first time have found a “quantum-confined bandgap narrowing mechanism”, where UV absorption of solar energy can easily be extended into the visible light range. This mechanism may one day allow the design of a new class of composite materials for light harvesting and optoelectronics.
Dr Qin Li, Associate Professor in the Environmental Engineering & Queensland Micro- and Nanotechnology Centre, says real life application of this would be high efficiency paintable solar cells and water purification using sun light.
“Wherever there is abundant sun we can brush on this nanomaterial to harvest solar energy to create clean water,” she says.
