Design and Optimization of an Efficient Molybdenum Disulfide (MoS2) Solar cell with Tin Sulfide BSF

Two-dimensional molybdenum disulfide (MOS
₂
) is a potential sunlight harvester due to low cost, layered type atomic structure, favorable electrical and optical properties. The performance of a molybdenum disulfide (MOS
₂
) photovoltaic cell is investigated by using the wxAMPS simulator. The hidden potentiality of MoS
₂
is unfolded by using BSF strategy. The photoconversion efficiency is found 21.39% (J
