Aussie boffins boost solar cell efficiency

"Australian scientists have unveiled research which they believe could pave the way for cheaper and more efficient solar panels.

The breakthrough at the University of New South Wales (UNSW) could see the price of an installed domestic solar system fall by around 30 per cent.

Up to 45 per cent of the cost of solar cell technology is due to the silicon used in cells to convert sunlight to electricity.
...

Once the technology approaches 15 per cent efficiency, it becomes commercially viable, Catchpole believes.
