Imagine the environmental benefits if we could all simply paint solar cells onto the roof of our houses, or onto any surface for that matter. We could do this using perovskite solar cells (PSC), but, due to their instability, they have not yet been widely introduced. Now, researchers from the Graphene Flagship have developed hybrids of graphene and molybdenum disulphide quantum dots to stabilize PSCs.   Progress in PSCs means that they are primed to become an affordable and flexible solar cell...
