摘要

我们使用全波有限元计算方法研究包含硅纳米线阵列的光伏电池。研究了太阳光与裸纳米线以及与附着在介质纳米天线上的纳米线的相互作用。我们计算了每种情况下的吸收光谱，并比较了结果，以确定用于太阳能应用的纳米线-纳米天线元件的可能的最佳混合物。我们还通过利用纳米线阵列内的场强模式进一步研究了吸收的增强。结果说明了在纳米线太阳能电池中使用介电纳米天线的好处。

Photovoltaics with dielectric nanoantennas

We investigate photovoltaics incorporating standing nanowire arrays of silicon using a full wave finite element computational approach. The interaction of sunlight with bare nanowires and also with nanowires attached to dielectric nanoantennas are studied. We compute the absorption spectra in each case and compare the results to determine a possible optimal mixture of nanowire-nanoantenna elements for solar applications. We also investigate further the enhancement of absorption by exploiting field intensity patterns within the nanowire arrays. The results illustrate the benefits of using dielectric nanoantennas for applications in nanowire solar cells.
