Crystalline silicon (c-Si) solar cells play an important role in the photovoltaic (PV) industry and make PV electricity begin to realize grid parity. Nevertheless, conventional c-Si solar cells are sensitive to angle of incidence (AOI) and have less power conversion efficiency ( η ) under oblique AOI, which influences the maximization of daily/yearly power output as the sun moves with time. Although the use of sun-tracking systems is an effective way to solve this problem, it is costly. As regards increasing the daily/yearly power output with low cost, quasi-omnidirectional c-Si solar cells are good candidates and have attracted considerable interest. The η of these solar cells is insensitive to AOI within a large range (for example, <60°) due to their quasi-omnidirectional antireflection ability. In this article, we will review different antireflection mechanisms and show how to realize quasi-omnidirectional antireflection in c-Si solar cells by specific structur...

准全向晶体硅太阳能电池

晶体硅（c-Si）太阳能电池在光伏（PV）工业中起着重要作用，并使光伏发电开始实现电网平价。然而，常规的c-Si太阳能电池对入射角（AOI）敏感，并且在倾斜AOI下具有较小的功率转换效率（η），这会影响太阳随时间移动时日/年功率输出的最大化。尽管使用太阳跟踪系统是解决此问题的有效方法，但成本很高。关于以低成本增加每日/每年的功率输出，准全向c-Si太阳能电池是不错的选择，并且引起了极大的兴趣。这些太阳能电池的η由于具有准全向抗反射能力，因此在大范围内（例如，<60°）对AOI不敏感。在这篇文章中，
