Numerical evaluation of bi-facial ZnO/MoTe₂ photovoltaic solar cells with N-doped Cu₂O as the BSF layer for enhancing <i>V</i> _OC <i>via</i> device simulation.

ABSTRACT: Molybdenum telluride (MoTe₂) shows great promise as a solar absorber material for photovoltaic (PV) cells owing to its wide absorption range, adjustable bandgap, and lack of dangling bonds at the surface. In this research, a basic device structure comprising Pt/MoTe₂/ZnO/ITO/Al was developed, and its potential was assessed using the SCAPS-1D software. The preliminary device exhibited a photovoltaic efficiency of 23.87%. The integration of a 100 nm thick nitrogen-doped copper oxide (N-doped Cu₂O) layer as a hole transport/BSF layer improved the device performance of the MoTe₂/ZnO photovoltaic solar cell (PVSC), increasing the open circuit voltage (V _OC) from 0.68 V to 1.00 V and, consequently, its efficiency from 23.87% to 34.45%
