Researchers at the University of New South Wales’ Australian Centre for Advanced Photovoltaics have developed a solar cell with a conversion efficiency of 34.5% – a new world record for non-concentrated sunlight.
The record was set using a 28 cm2 four-junction mini-module embedded in a prism that splits the incoming rays into four bands. A silicon cell is on one face of the glass prism, with a triple-junction solar cell on the other. The triple junction cell is made up of a layer each of indium-gallium-phosphide; indium-gallium-arsenide and germanium. Each layer utilises different light bandwidth to generate electricity.
A new poll indicates close to two-thirds of Australians (64%) would be more likely to vote for a party with plans to source 100 per cent of Australia’s energy from renewables.
The Reachtel poll of 2,400 Australians also indicates 56.1 per cent would be more likely to vote for a party with a policy to phase out coal-fired power stations.
Another significant U.S city is making solar mandatory on new residential and commercial buildings.
The Santa Monica City Council voted last month to require all new residential and commercial construction to incorporate solar panels – and the ordinance takes effect in just a couple of weeks’ time.
Dozens of America’s biggest companies have joined with several non-profit organisations to form the Renewable Energy Buyers Alliance (REBA), which has set a goal of developing 60 GW of new renewable capacity by 2025.
