Cheap Dye-Sensitized Solar Cell Moves Toward Commercialization

from 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. more
