Scientists from mit found out that the sandwiches from monatomic materials graphene and molybdenum compounds can be used as a record of thin solar cells.
In most cases the efforts of developers that are associated with the improvement of solar batteries was directed on increase of efficiency of energy conversion, or on lowering the cost of production.
American scientists created solar cells have the form of sandwiches of two different two-dimensional substances with a thickness — one atom. In one embodiment, used molybdenum sulfide MoS2 c graphene, in other — the same connection with the tungsten sulfide is WS2.
In recent years, researchers have paid much attention to the potential of two-dimensional materials such as graphene, but so far few people have used their development in the field of solar cell production.
The effectiveness of new solar panels is only close to one percent against the 15-20% of existing solar cells. But based on the mass, monatomic sheets have no equal — they get at least a thousand times more energy with minimal weight.
