Unlike the solar cells you’re used to seeing, organic photovoltaics are made of compounds that are dissolved in ink and can be printed and molded using simple techniques. The result is a low-weight, flexible, semi-transparent film that turns the energy of the sun into electricity. Hannah Bürckstümmer shows us how they’re made – and how could change the way we power the world.
There’s an energy revolution happening in villages and towns across Africa – off-grid solar energy is becoming a viable alternative to traditional electricity systems. In a bold talk about a true leapfrog moment, Amar Inamdar introduces us to proud owners of off-grid solar kits – and explains how this technology has the opportunity to meet two extraordinary goals: energy access for all and a low-carbon future. “Every household a proud producer as well as consumer of energy,” Inamdar says. “That’s the democracy of energy.” (Followed by a brief Q&A with TED Curator Chris Anderson)
