Abstract
This invention relates to cells and devices for harvesting light. Specifically the cell comprises at least one electrode which comprises graphene or modified graphene and layer of a transition metal dichalcogenide in a vertical heterostructure. The cell may be part of a light harvesting device. The invention also relates to materials and methods for making such cells and devices.
Claims20
A photovoltaic cell comprising a two-dimensional graphene heterostructure.
A heterostructure comprising:
- a first layer which comprises graphene or modified graphene (e.g. doped graphene);
- one or more layers comprising WS2;
- a second layer which comprises graphene or modified graphene (e.g. doped graphene);
- wherein the layers are stacked sequentially to form a laminate structure and the or each layer of WS2 is situated between the first and the second graphene layer.
