309: The Solar Panel That Beats Silicon's Limit

Perovskite solar has promised a revolution for over a decade, so is it finally real? Matt and Sean talk with Joel Jean, co-founder and CEO of Swift Solar, the US startup spun out of MIT and Stanford. Joel explains how stacking a perovskite film on top of silicon lifts a solar cell's efficiency ceiling from 30 percent to about 45 percent. He also breaks down the three "tooth fairies" every new solar technology has to solve: performance, lifetime, and cost. So is perovskite tandem solar finally ready for your roof? Or is 25 year durability still one miracle away?
