A team of researchers, affiliated with UNIST has come up with a novel electrode that could greatly improve the stability of perovskite solar cells (PSCs), the most promising candidate for the next generation solar cells due to their low cost and high power conversion efficiency. This is because inserting a protection layer between the metal-based electrode and the perovskite film can prevent metal-induced degradation and that graphene, as such a layer, can effectively suppress the diffusion of metals and halide ions.
