研究目的
Investigation of energy band gap, absorption coefficients and module implementation cost for 1KW solar power plant for ternary AB2X4 (A= Cd; B= Ga; X= S, Se) solar photovoltaic (PV) system to determine its cost-effectiveness compared to Crystalline Si.
研究成果
The study concludes that CdGa2Se4 poses an ideal band gap value for maximum absorption of solar incoming radiation and is comparatively less expensive and more efficient than other compounds, making it a cost-effective option for commercialization compared to Crystalline Si.
研究不足
The study assumes a material thickness of 200 microns for cost calculations, which may not account for variations in actual manufacturing processes. The efficiency values used for cost comparison are based on literature and may vary in practical applications.
1：Experimental Design and Method Selection:
Full potential linearized augmented plane wave (FP-LAPW) based density functional theory (DFT) approach was implemented to study electronic and optical behavior of proposed materials. Cost related calculations were performed using mathematical expressions.
