Coal-Killing Perovskite Solar Cell Problem Solved (Almost!) With Graphene | CleanTechnica

Coal-Killing Perovskite Solar Cell Problem Solved (Almost!) With Graphene | CleanTechnica
When two “wonder materials” of the solar energy age combine, good things happen. That’s the takeaway from new research that leverages graphene to create a more durable, efficient — and super cheap — perovskite solar cell. There are many next steps before this next-gen solar technology pops up on a rooftop near you, but the new development does keep the promise of perovskites alive — and brings the market for coal-generated electricity one step closer to doom.
