Graphene and other 2D materials for advanced solar cells

Due to their excellent electron-transport properties and extremely high carrier mobility, graphene and other other direct bandgap monolayer materials such as transition-metal dichalcogenides (TMDCs) and black phosphorus show great potential to be used for low-cost, flexible, and highly efficient photovoltaic devices. A rcent review provides a comprehensive overview on the current state-of-the-art of 2D-materials-based solar photovoltaics. It describes the recent progress made with graphene, graphene-based materials, and other 2D materials for solar photovoltaics, including silicon-based solar cells, and organic and perovskite solar cells.
