Cost Effective Generation of solar energy Using Titanium dioxide
Jonathan Goldsteinan, Israeli chemist came across a novel way to produce inexpensive, clean solar energy. 3GSolar, the company born of that serendipitous discovery, is now poised to light up the developing world.
Goldstein's deceptively simple solution is set to revolutionize dye-sensitized solar cell (DSC) technology, invented in 1988 by Swiss scientist Michael Graetzel. The cells are photovoltaic (PV), meaning they convert radiant energy - such as sunlight -- into electricity with the help of a layer of semiconductor. The larger DSC could be a cheaper and more available alternative to silicon, the relatively expensive and scarce semiconductor currently used in most solar-energy panels. Silicon solar panels are also costly to produce.
A cheap white powder called titanium dioxide had a track record in DSC technology. If treated with an absorbable dye, titanium dioxide becomes sensitive to light.We can easily screen-print thin layers of titanium dioxide on surfaces and churn out plates of this material and then oven-bake the layer on firmly - it can even be baked on in the air, with no need for expensive equipment.Goldstein's low-cost current collector enabled building tablemat-sized cells and extracting the generated current.The glass-based titanium-dioxide-treated panels are expected to debut at half the cost of similarly sized silicon panels.
