چکیده :

This article examines and optimizes the structural parameters of InAlGaP solar cells and evaluates the impact of various anti-reflective coatings on their performance. Extensive simulations revealed that optimizing the window layer thickness and impurity concentration can achieve an efficiency of 28.5646%. Subsequently, the effects of five anti-reflective materials, including Ge, CIGS, GaInP, Silicon, and ZnO, on the solar cell's performance were assessed. In this study, GaInP and Silicon exhibited the best performance with efficiencies of 31.5441% and 31.5295%, respectively. Parametric analysis indicated that increasing the thickness of the anti-reflective layer leads to a decrease in efficiency; however, Silicon demonstrated less sensitivity to thickness variations. These results underscore the importance of simultaneous optimization of structural parameters and careful selection of anti-reflective materials in designing high-efficiency solar cells. The findings of this research were analyzed through numerical modeling using Silvaco/Atlas software under AM1.5 spectrum irradiation. The key performance metrics for the proposed optimized structure of the solar cell with a silicon anti-reflective coating were as follows: Isc = 20.2459 mA/cm², Voc = 1.75 V, FF = 88.9887%, and η = 31.5295%. These results indicate a high efficiency for the proposed structure in enhancing light absorption and converting solar energy.
