Two important aspects must be considered when optimizing antireflection coatings (ARCs) for multijunction solar cells to be used in concentrators: the angular light distribution over the cell created by the particular concentration system and the wide spectral bandwidth the solar cell is sensitive to. In this article, a numerical optimization procedure and its results are presented. The potential efficiency enhancement by means of ARC optimization is calculated for several concentrating PV systems. In addition, two methods for ARCs direct characterization are presented. The results of these show that real ARCs slightly underperform theoretical predictions.
在为聚光器中使用的多结太阳能电池优化减反射涂层（ARC）时，必须考虑两个重要方面：特定聚光系统在电池上产生的角光分布以及太阳能电池敏感的宽光谱带宽。本文介绍了一种数值优化程序及其结果。针对几种聚光光伏系统计算了通过ARC优化可能提高的效率。此外，还介绍了两种直接表征ARC的方法。这些方法的结果表明，实际的ARC性能略低于理论预测。
