中文摘要 AI 辅助

在本工作中,我们研究了钙钛矿纳米线(PrvNWs)对光的吸收,以用作太阳能电池中的活性层。具体而言,我们模拟了在AAO膜孔内随机位置的PrvNWs。结果表明,与相应的有序PrvNW阵列相比,这种垂直无序可以增强光吸收,短路电流最高提升28%。这种性能提升归因于光捕获和抗反射效应的结合。因此,我们的发现表明,垂直无序的PrvNWs可以比有序阵列具有更好的性能。此外,我们证明了无需追求纳米线极窄的长度分布,从而放宽了制造要求。

英文摘要

In this work, we investigated the absorption of light in perovskite nanowires (PrvNWs) for application as active layer in a solar cell. Specifically, we simulated PrvNWs with a random position inside the pores of an AAO membrane. The results demonstrate that this vertical disorder can boost light absorption, up to 28% in terms of short-circuit current, in comparison to the corresponding ordered PrvNW array. This performance boost is due to a combination of light trapping and anti-reflection effect. Thus, our findings suggest that vertically disordered PrvNWs can have a much better performance than ordered arrays. Also, we showed that it is not necessary to aim for a very narrow length distribution in the nanowires, easing the fabrication requirements.
