While their manufacturing process uses fewer silicon wafers they neglect to say how much that will reduce the manufacturing cost of their cells.
A joint venture between the Australian National University and Origin Energy has developed a new type of solar cell with the potential to revolutionise the global solar power industry.
Director of the ANU Centre for Sustainable Energy Systems, Professor Andrew Blakers today unveiled the Sliver CellTM, which uses just one tenth of the costly silicon used in conventional solar panels while matching power, performance and efficiency.
Professor Blakers said, "A solar panel using Sliver CellTM technology needs the equivalent of two silicon wafers to convert sunlight to 140 watts of power. By comparison, a conventional solar panel needs about 60 silicon wafers to achieve this performance.
"By dramatically reducing the amount of expensive pure silicon, the largest cost in solar panels today, this new technology represents a major advance in solar power technology."
Origin Energy's Executive General Manager, Generation, Andrew Stock said, "Origin Energy has worked with ANU's Centre for Sustainable Energy Systems for several years, investing more than $6 million in research to discover a way to harness the sun's power at much lower cost.
"Due to the economy and flexibility of Sliver CellsTM, we believe this technology will play an important role in the future wide-spread adoption of solar power. Sliver CellTM technology is an excellent example of the way Australian researchers can work with Australian industry to innovate a product that leads the world".
ANU Vice-Chancellor, Professor Ian Chubb welcomed the research breakthrough. "Origin Energy is to be congratulated for its foresight and persistence in supporting the ANU team in this project. The company has made a substantial contribution since establishing the research partnership with ANU," Professor Chubb said.
The most expensive part of traditional solar power panels is the silicon from which the individual cells are made. The Sliver CellTM is a radically different concept in photovoltaics. Sliver CellsTM are produced using special micro-machining techniques, then assembled into solar panels using similar methods to those used to make conventional solar panels.
The new technology reduces costs in two main ways – by using much less expensive silicon for similar efficiency and power output, and needing less capital to build a solar panel plant of similar capacity.
The unique attributes of Sliver CellTM technology could open many new Sliver CellTM applications, in addition to conventional rooftop and off-grid uses, including:
- Transparent Sliver CellTM panes to replace building windows and cladding
- Flexible, roll-up solar panels
- High-voltage solar panels, and
- Solar powered aircraft, satellite and surveillance systems
