Cadmium Telluride (CdTe) solar cells have been successful and promising in producing solar energy at commercial scales and power plants. That is mainly due to the versatility in manufacturing of efficiency and cost-effective modules recently. The major widely utilised material for solar PV cell manufacture represents CdTe because of its excellent light-absorbing capacity and ideal energy band gap. Though the technology of CdTe PV has benefits, the limited supply of Te proves to be an issue currently. The thickness of CdTe can be reduced without affecting the efficiency significantly. CdTe photovoltaic solar cells with single and double absorber layers of ultrathin layers have enhanced efficiencies and reduced costs. It is necessary to improve how these solar cells absorb light. Making the layer narrower can help to cut down on the amount of material required, as well as costs related to fabrication. Using thin layers of material can reduce the cost and amount of material needed for fabrication. To ascertain the feasibility of suggested solar designs and forecast how material characteristics will impact their overall effectiveness, thin film solar cell architectures can be modelled utilizing computer simulations. The efficacy as well as parameter effectiveness of ultrathin CdTe Photovoltaic (PV) cells were simulated in SCAPS-1D simulation software as a function of acceptor concentration and the thickness of the light absorption layer. A double absorber layer with NiO as the windowed layer as well as FeSi<sub>2</sub> as the secondary layer was investigated in order to enhance the PV system's device features as well as parameters.
