AP01025 Numerical Modelling of High Efficiency ZnO/GaAs Solar Cell Using Single Layer Anti-Reflective Coating (SLARC)

Abstract

Zinc oxide, ZnO, and gallium arsenide, GaAs, are a pair of materials that can build a good structure for a solar cell device as n-type and p-type, respectively. Both materials were promising good efficiency due to their optical and electrical properties in semiconductors. For that, the thickness of the material of SLARC was calculated using a formula to investigate the efficiency between 250 nm and 1200 nm of wavelength. The efficiency of the n-ZnO/p-GaAs cell without using ARC recorded 17.76%, and applying SLARC of silicon dioxide, SiO₂, on top of the cell showed 19.62% using Personal Computer 1-Dimensional (PC1D) simulation.
