However, perovskite solar cells are much thinner than silicon cells - just tenths of a micrometer thick - making them cheaper to produce and ultra-lightweight. It means they can be seamlessly combined with glass panes; they can cover tiles (converting the entire roof into one huge photovoltaic panel); and can even be applied to the entire walls of modern buildings.
In all cases the result is the same: The creation of fossil-free electricity.
“My dream is to have solar cells that after some time will degrade like leaves on a tree – and can be replaced with new ones. Perovskites are partially organic, so it should be possible,” says Olga.
And to think, all of this very nearly didn’t happen. “The only reason I decided to attend the conference in Seville was because it was close to where I was living in Valencia. Had it been held further away, I probably wouldn’t have gone there!”
