Solid state solar panels are more affordable, say researchers, don't leak

Researchers at Northwestern University have found one way to stop a leak: get rid of the liquid. A new variation on the Grätzel solar cell replaces a short-lived organic dye with a solid alternative. The molecular dye the solid substance replaces was corrosive, at risk of leaking and only lasted about 18-months - by replacing it, researchers plan to pave the way for a more affordable (and less toxic) alternative. Northwestern's new design flaunts a 10.2-percent conversion efficiency, the highest ever recorded in a solid-state solar cell of its type - but that's still only half of what traditional sun collectors can do.
