Solar modules on the International Space Station

UNSW researchers set world record in Solar Energy efficiency, by converting 40% of the sunlight power into electricity.

University of New South Wales‘s solar scientists have converted over 40% of the sunlight hitting a solar system into electricity, after a long line of achievements, the highest efficiency ever reported. The first photovoltaic system to convert sunlight to electricity with over 20% efficiency was set way back in 1989.

UNSW Professor Professor Martin Green, Director of the Australian Centre for Advanced Photovoltaics (ACAP), said:

“This is the highest efficiency ever reported for sunlight conversion into electricity.

The new results are based on the use of focused sunlight, and are particularly relevant to photovoltaic power towers being developed in Australia.”

Dr Mark Keevers, the UNSW solar scientist and manager of the project, added:

“We used commercial solar cells, but in a new way, so these efficiency improvements are readily accessible to the solar industry.”

Power towers are being developed by Australian company, RayGen Resources, which provided design and technical support for the high efficiency prototype.
