The coal lovers aren't going to like this one. Despite Abbott trying to kill off the renewables industry here, science marches on. In this case very local science from the University of New South Wales (UNSW) which is just down the road from our place. How lovely, living near such deep thinking scientific intelligent people :)
To achieve this 40% efficiency involves using filters that stop some bandwidths of light but let others through:
UNSW Australia's solar researchers have converted over 40% of the sunlight hitting a solar system into electricity, the highest efficiency ever reported.
The record efficiency was achieved in outdoor tests in Sydney, before being independently confirmed by the National Renewable Energy Laboratory (NREL) at their outdoor test facility in the United States.
The work was funded by the Australian Renewable Energy Agency (ARENA) and supported by the Australia-US Institute for Advanced Photovoltaics (AUSIAPV).
"This is the highest efficiency ever reported for sunlight conversion into electricity," UNSW Scientia Professor and Director of the Advanced Centre for Advanced Photovoltaics (ACAP) Professor Martin Green said.
"We used commercial solar cells, but in a new way, so these efficiency improvements are readily accessible to the solar industry," added Dr Mark Keevers, the UNSW solar scientist who managed the project. more
