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.
