Cubic Mixed Semiconductor BAs:N Compounds for Energy Harvesting and Photovoltaic Applications

الخلاصة

Recently, mixed crystal semiconductors containing BAs:N have garnered significant attention for the next generation of photovoltaic applications owing to their optoelectronic and elastic properties with moderate energy band gap (Eg). According to Vegard’s law, lattice constants undergo slight variations under various condensation conditions. When Born–Huang (BH) stability criteria were applied to determine elastic parameters, the calculated Eg value of BAs1−xNx decreased concerning the increase in As condensation. It was found that these elastic constant values easily fulfilled the BH stability criteria, mechanically stabilizing BAs1−xNx. Moreover, the elastic moduli, Poisson's ratio and other properties were calculated. Our results suggest that BAs1−xNx compounds are ideal candidates for utilization in the above devices. Additionally, the calculated optical properties of this alloy indicated that BAs1−xNx is suitable for practical photo-sensing and photovoltaic applications due to its vast spectral region ranging from ultra-violet to visible, higher absorption peaks, and overall Eg values. The study provides a route for experimental work on photovoltaic applications based on cubic semiconductors. © 2022, The Minerals, Metals & Materials Society.
