Solar researchers at the University of New South Wales (UNSW) in Australia have been able to convert solar energy into electricity more than 40%, the highest so far. A paper describing this outcome will be published in the upcoming issue of Solar PV Progress.
The new record was obtained in an outdoor test in Sydney and was confirmed on an outdoor test facility at the National Renewable Energy Laboratory (NREL). This work was funded by the Australian Renewable Energy Agency and supported by the Australian-American Advanced Optoelectronics Research Institute. Dr. Mark Kiworth, a solar scientist in charge of the project, said: "This advancement has already provided stable support for solar power plants."
The milestone 40% conversion rate is a long-term achievement of the University of South Wales' 40-year study. In 1989, the first photovoltaic system achieved a conversion rate of more than 20%, and now the result is twice that of the time. “This new result is related to the use of the Australian Photovoltaic Energy Tower,†said Professor Martin Green, Institute of Optoelectronics.
Developed by Australia's Light Generator Resources, the Energy Tower provides design solutions and technical support for high-efficiency prototypes. Another collaborator is the American "Spectrum Laboratory" company, which provides some batteries for use in the project.
According to a report by the Physicist Network on December 8 (Beijing time), a key part of the prototype design is the use of a custom optical bandpass filter on the energy tower that reflects light at specific wavelengths and captures it. More sunlight, which is often wasted by commercial batteries, is converted into electricity with high efficiency that current solar cells simply cannot.
The Chief Executive of the Australian Renewable Energy Agency, Yves Frisie Klett, said that the successful development of the prototype is a new era for Australian R&D institutions, and will prove the value of Australia's investment in new energy innovation. "We hope that this independent innovation can move forward from prototype to experimental demonstration, and eventually more efficient commercial solar power plants can reduce the cost of new energy and increase core competitiveness."
