With a tip of the hat to Charlie Martin, a team of Australian scientists just blew away the previous record for solar conversion efficiency:
A team from the University of New South Wales, Australia, just set a new world record for solar energy efficiency by successfully converting 40.4% of available sunlight into electricity. And what’s even more remarkable is the fact that the record was achieved by using commercially available solar cells in a new way – which means, as the team explains, “these efficiency improvements are readily accessible to the solar industry.”
The efficiency record was first set outdoors in Sydney, and was then independently confirmed by the National Renewable Energy Lab in the United States. The photovoltaic technology used by the UNSW team differs from conventional solar cell technology in one key way: it utilizes triple-junction solar cells. These cells, as Motherboard explains, “are basically a sandwich of differently tuned semiconductors with each one able to capture a different wavelength of sunlight.”
As the innerweb saying goes — faster, please.
Casa Verde has some excellent southern exposure, and my part of the state is famous for averaging 300 days of sunny skies each year. Melissa and I have looked just a little into adding enough solar panels to our electrical system to take the edge off those rising electricity prices.
If the Aussies really can deliver those efficiencies at affordable prices with COTS materials, then we might be able to make a decision sooner than we thought.
Or are we dreaming?
