Multi-cell combination that is able to convert 43 percent of sunlight into electricity:
The world-record holding cell was fabricated by former Centre researchers, Dr Jianhua Zhao and Dr Aihua Wang. The cell is converting 43% percentage of light. The new technology is now six per cent more efficient than the next-best technology.
Why? Because of the combination the silicon cell with others cells which they are made from gallium, indium, phosphorus and arsenic. Thanks to this combination, the capture of light at one side of the spectrum where there is a red and near-infrared. It’s this part of the spcetrum that helps with the great convertion rate. It’s a new world record.
Professor Green said: “These light-trapping features make our cells act as if they were much thicker than they are. This already has had an important spin-off in allowing us to work with CSG Solar to develop commercial ‘thin-film’ silicon-on-glass solar cells that are over 100 times thinner than conventional silicon cells.” ARC Centre Director, Professor Stuart Wenham said the focus of the Centre is now improving mainstream production. “Our main efforts now are focussed on getting these efficiency improvements into commercial production,” he said. “Production compatible versions of our high efficiency technology are being introduced into production as we speak.”
