摘要

In this study, we have grown the nano-structural ZnOZnO:Al film as anti-reflection coating layer on triple junction solar cells and subsequently characterized their performances. In spite of the superior electrical characteristics of ZnO:Al layer deposited by radio frequency sputtering, a large reflectance of ZnO:Al film on GaAs leads to reduction of incident light. With nano-structural ZnOZnO:Al antireflection coating layer implemented, the conversion efficiency of GaAs based triple junction solar cells have enhanced from 21 to 26.2 under AM 1.5 global illumination (100 mwcm ~2) and it can be further improved up to 32 with 160-sun illumination.
