Efficiency Enhancement of GaAs Photovoltaics Employing Antireflective Indium Tin Oxide Nanocolumns

Abstract

Highly-oriented indium tin oxide nanocolumns are prepared by glancing-angle deposition with nitrogen. The tapered column profiles, which function as a graded-refractive-index layer, offer superior antireflective characteristics. The nanostructured material serves as the conductive antireflective layer for GaAs solar cells, demonstrating a viable efficiency-boosting strategy for next-generation photovoltaics.
