In this study, the SCAPS-1D tool has been used to numerically examine the performance of Transition Metal Dichalcogenides (TMDC) based Molybdenum ditelluride (MoTe₂) solar cells containing CdS electron transport layer (ETL) and Cu₂O hole transport layer (HTL). Based on the photovoltaic cell parameters, including absorber layer thickness, temperature, defect density, the effects of series and shunt resistance, and electron affinity, the structure of both MoTe₂ based solar cells with and without the usage of the HTL has been analyzed. With 1.1 μm thickness of MoTe₂ and doping density of 5 × 10¹⁵ cm⁻³, Al/FTO/CdS/MoTe₂/Cu₂O/Ni heterojunction’s solar cell proposed structure has been optimized. The final power conversion efficiency (PCE) = 32.38%, open-circuit voltage (V_oc) = 1.07 V, short-circuit current (J_sc) = 35.12 mA/cm², and fill factor (FF) = 86.32% has been determined from the optimized structure. The determined results indicate a suitable path for the realization of low cost and high efficiency MoTe₂-based solar cell.
