Optimum Antireflection Coatings for Heteroface AlGaAs/GaAs Solar Cells-Part Ⅰ: The Influence of Window Layer Oxidation

摘要

This paper details both the theoretical and experimental results of a modified model for designing MgF_2/ZnS double-layer antireflection coatings for AlGaAs/ GaAs heteroface solar cells. The main contribution of the model presented is that It takes into account the possible existence of an oxide layer in the AlGaAs Window layer. In a first step the optical behavior of the oxide is modeled and that Model is used to recalculate optimal double-layer antireflection coating when a Thin AlGaAs oxide layer is present.
