Abstract : Power conversion efficiency (PCE) is the main parameters to evaluate the output characteristics of solar cell. The anti-reflective coating (ARC) play role to inhibit the light loss on the solar cell surface, hence enhancing the PCE. This paper studies the different materials of double-layer anti-reflective coating (DLARC) on crystalline silicon (c-Si) solar cells. The overall process methodology for simulating a silicon solar cell was done by using the Wafer Ray Tracer from PV Lighthouse software. Five light trapping (LT) schemes with different types of double layers were examined. The maximum potential photocurrent density (Jmax) of c-Si with ARC showed an improvement over the Jmax of the reference c-Si (without ARC). LT Scheme II: SiO2/TiO2 produces the greatest value of Jmax where the value is 42.20 mA/cm2. This shows that Schemes II had the highest Jmax enhancement, at a value of 10.01%. This finding implies that DLARC applicable in reducing the optical loss, hence effectively boost the performance of solar cell.
