The Sb<sub>2</sub>(S,Se)<sub>3</sub> layer creates a conduction band offset that acts as an effective barrier to electron backflow, thereby suppressing carrier recombination at the rear contact. Comprehensive simulations are conducted to analyze how the electron barrier influences the photovoltaic output, focusing on key parameters including interface defect density at the EBL/CIGS and within the CIGS absorber, rear surface recombination velocity, and Nyquist characteristics. The conduction band alignment at the Sb<sub>2</sub>(S<sub>1−x</sub>Se<sub>x</sub>)<sub>3</sub>/CIGS is tuned by varying the Se-to-S ratio, enabling control over the conduction band offset to optimize carrier selectivity. The results reveal that for compositions with x < 0.7, the device benefits from a favorable conduction band barrier, resulting in a notable increase in V<sub>oc</sub> due to suppressed recombination at the rear interface. The slight increase in J<sub>sc</sub> results from improved long-wavelength carrier collection due to reduced rear interface recombination enabled by the optimized conduction band alignment of the Sb<sub>2</sub>S<sub>3</sub> layer.

The substitution of a single carbon atom with a Boron (Nitrogen) atom shifts the Fermi energy to the valence (conduction) band, thereby transitioning the material from a semiconductor to a metallic state.

Our investigation reveals that the porous graphene structure remains stable under a symmetrical biaxial planar strain up to an intensity of 10%, beyond which some C-C bonds reach the threshold of rupture. By applying uniaxial strain distributions along the symmetry lines, as well as tensile and compressive symmetrical biaxial strain distributions with different intensities (less than 10%), the bandgap can be continuously modulated over a wide range. Specifically, applying a symmetrical tensile biaxial strain with an intensity of 10% increases the bandgap value to 3.024 eV. Conversely, applying a symmetrical compressive biaxial strain with an intensity of 6% reduces the bandgap to 1.671 eV. In general, increasing the intensity of the tensile strain leads to an increase in the bandgap value, while increasing the intensity of the compressive strain causes its reduction.
