>>could improve Med Imaging/ Cancer Rx’s + Increase Solar Cell efficency by 25 – 30%. Goal is to turn low-energy colors of light, such as red, into higher-energy colors, like blue/green. A traditional solar cell can only absorb light with energy above a certain threshold. Infrared light passes right through, its energy untapped. But if low-energy could be transformed into higher-energy light, a solar cell could absorb more.
UD’s College of Engineering’s A/Prof Matthew Doty said; “You can’t simply turn a red photon into a blue one, but you can combine the energy from two or more red photons to make one blue photon.” …”Photon upconversion” isn’t new but UD team’s approach is. They want to design a new kind of semiconductor nanostructure that will act like a ratchet...
