Thus, there are tremendous opportunities to develop 2D material–based photovoltaic solar cells by improving the synthesis of high-quality large-scale layered semiconductors, designing heterostructure of 2D materials for high absorption of solar spectrum and engineering the solar cell devices for better performance.
Depending on the device geometry, the 2D heterostructure photovoltaic devices can be classified into two categories: (1) lateral configuration where the built-in electric field is in the in-plane direction of 2D material, another is (2) vertical configuration where the electric field is in the perpendicular direction of the plane of 2D materials.
Growing large-scale vertical heterostructure with different bandgap of materials could be a challenging task but a suitable, low-cost transfer process for large size crystals will lead to better 2D-based photovoltaic solar cells.
In case of lateral p-n junction device, bP can degrade quickly due to the exposure to the oxygen atmosphere which destroys the device completely within few hours [ 65 ]. Thus, this work demonstrated the potential application of vertical p-n junction heterostructure for photovoltaic solar cell applications.
