Development of a Multi-layer Anti-reflective Coating for Gallium Arsenide/Aluminum Gallium Arsenide Solar Cells

Abstract

A process for calculating the true refractive index of an as-deposited dielectric for use as an anti-reflective (AR) coating was established. Yttrium oxide and tantalum oxide were used in the design of multi-layer AR coatings for use with gallium arsenide (GaAs) solar cell devices. These AR coatings were found to greatly reduce the reflective losses from the surface of the GaAs, therefore increasing the external quantum efficiency of the device.
