Solar Power World Record

23-09-2009 9:13am#1Linky..Australian solar cell researchers have played a key role in achieving the highest efficiency for solar power ever recorded, setting a new world record of 43 per cent of sunlight converted into electricity.Instead of being made from silicon, those cells were made with more expensive compound semiconductors using combinations of gallium, indium, phosphorus and arsenic, with each assigned to its own specific colour band in the light spectrum - ranging from UV to far-infrared - for optimal conversion.
Ok not really cost effective on a big scale yet..
But we're getting there
