Enhancement of Gallium Arsenide GaAs and Diluted Nitride 4-Junction Solar Cells

Abstract

Surface reflection of incident light negatively impacts solar cell performance. This can be rectified by applying an anti-reflection coating (ARC). This study examines the effect of double-layer ARC materials deposited by different techniques including thermal evaporation and plasma-enhanced chemical vapor deposition onto dilute nitride GaAs multi-junction solar cells. The effect of double–layer ARC on dilute nitride GaAs multi-junction solar cells is investigated by comparing optical and electrical properties of coated and uncoated cells. Ellipsometry and reflectometry were used to assess optical qualities, while quantum efficiency tests and electrochemical capacitance-voltage analysis were applied to quantify electrical properties.
