Abstract:
Two-dimensional molybdenum disulfide (MoS2) is a
potential sunlight harvester due to low cost, layered type atomic
structure, favorable electrical and optical properties. The
performance of a molybdenum disulfide (MoS2) photovoltaic cell
is investigated by using the wxAMPS simulator. The hidden
potentiality of MoS2 is unfolded by using BSF strategy. The
photoconversion efficiency is found 21.39% (Jsc = 29.89 mA/cm2,
Voc = 0.841V and FF=0.856) for 1 μm MoS2 absorber layer with
100 nm SnS BSF whereas in conventional structure, it is found
19.48% (Voc = 0.826V, Jsc = 27.848 mA/cm2, and FF = 0.846)
without BSF for 1 μm MoS2 absorber layer. The measured
temperature coefficient (TC) is -0.047%/°C for conventional
photovoltaic cell structure and -0.046%/°C for a modified
structure with SnS BSF. It indicates the better thermal stability
of the modified structure compared to the conventional structure.
