Cheap Dye-Sensitized Solar Cell Moves toward Commercialization

technology review -- Easy-to-make solar cells that capture light with dyes have garnered an impressive string of scientific awards, including the Millennium Technology Prize in 2010. Yet they've had little commercial impact since their invention in 1988.

A novel design reported by Northwestern University researchers last week could change that, delivering a device that eliminates the dye-sensitized solar cell's inherent liability: its leak-prone and corrosive liquid electrolyte.

Unlike thin-film and silicon panels, dye-based panels can be produced in cheap roll-to-roll processes akin to printing. So even if they are less efficient than silicon solar cells, they could prove cost-effective.

The Northwestern development is just the latest in a string of advances in what Michael McGehee, director of Stanford

tomok Champion Author Portland Posts:32,975 Points:2,344,535 Joined:Aug 2006	Message Posted: May 31, 2012 4:26:00 AM Ignore tomok Report Abuse A new type of solar cell (1988?) that you hear about and never see or produced. Cheap and efficient solar panels needed. Cheaper renewable electricity produced from solar, wind, hydro, tidal, thermal and/or nuclear. Whatever the size or shape of the vehicle, Produce and ‘Drive’ vehicles with high MPG, are very reliable, have a ‘reasonable’ cost and a good ‘value’ for the money. Consider using other forms of less expensive transportation to lower your cost, if possible. The price of fuel at the pump is too high! 12/22/2012!

Apparently the Powers-That-Be kept this thing under wraps until they could figure out how to use it to pile up the profits. Just like they do their best to hide other things like inexpensive yet more effective medical breakthroughs that might cause highly profitable pharmaceuticals or procedures to become worthless.
