Graphene-MXene nanofluid in a passive heat pipe dropped a solar panel temperature by 24C and boosted output by 15%, at a cost that keeps electricity competitive. Perovskites, tandem junctions, heterojunctions — three competing solar cell designs. The next unlock might not be in the cell at all, b...
