摘要

This research addresses the challenges of single-layer anti-reflective coatings (SARCs) and emphasises the advantages of double-layer anti-reflective coatings (DARCs) in minimising reflectivity. The materials, titanium dioxide (TiO2) and silicon dioxide (SiO2), were examined for their potential to enhance the refractive indices of DARCs. This work aims to assess the effect of DARCs, specifically SiO2/TiO2, on the efficiency of gallium arsenide (GaAs) solar cells. Based on the results, the solar cell demonstrates the highest efficiency in converting light into electrical current at a wavelength around 600 nm for both SARCs and DARCs. The findings indicate that a DARC comprising TiO2 (higher refractive index) as the bottom layer and SiO2 (lower refractive index) as the upper layer achieved an outstanding efficiency of 21.02% at a wavelength of 600 nm. This optimal combination balances light absorption and reflection, leading to enhanced efficiency and power generation. Moreover, it can be determined that the 600 nm wavelength, within the visible light spectrum, is characterised by intense solar radiation, enabling the cell to capture a higher amount of solar energy effectively. The Personal Computer One Dimensional simulation software was used in this work to evaluate the effect of the DARC on the performance of the GaAs solar cell by analysing the short-circuit current (Isc), open-circuit voltage (Voc), maximum output power (Pmax), fill factor (FF), and the efficiency of GaAs solar cell.
