In the past two decades graphene has been merged with the concept of photovoltaic (PV) material and exhibited a significant role as a transparent electrode, hole/electron transport material and interfacial buffer layer in solar cell devices.
For instance, in organic solar cells, graphene can be used as electron acceptors and hole conductors. In heterojunctions solar cells, it is used to form Schottky junctions with semiconducting materials (CdSe, and n-Si), which facilitates electron-hole separation and diffusions driven by the built-in potential between graphene and semiconductors.
Recent research has shown that the incorporation of graphene-related materials improves the performance and stability of perovskite solar cells. Graphene is hydrophobic, which can enhance several properties of perovskite solar cells.
Graphene-based materials are also capable of functioning as charge selective and transport components in solar cell buffer layers. Moreover, low air stability and atmospheric degradation of the photovoltaic devices can be improved with graphene encapsulation due to its stable highly packed 2D structure.
