Researchers from the Graphene Flagship project have published an article on how the lifetime of perovskite solar cells can be significantly improved: by using solution-processed molybdenum disulfide (MoS₂) as an active buffer layer. In a summary on the project website, they write: "These PSCs retain 93% of the initial light conversion efficiency after 550 h, compared to only 66% for cells without the MoS2 buffer layer. This represents an important step towards viable PSCs, especially as the addition of the MoS₂ interface layer is compatible with low-cost solution processing techniques."
