In this work, a thin-film solar cell consists of metallic nanowires, semiconductor, and antireflection layers is investigated. The absorption of the structure is obtained numerically in the broadband wavelength range of 300–1700 nm. The influences of the layer thicknesses and the cross-section shape of metallic nanowires are studied. Results indicate that the absorption of the rectangular-nanowire system is over 90% in the range of $560-1180nm$. Also, the absorption in the range of $300-1200\text{ nm}$ is over 90% when the cross-section of nanowires is semi-circular. This high absorption in the visible region could be helpful in designing plasmonic solar cells.

在这项工作中，研究了由金属纳米线、半导体和抗反射层组成的薄膜太阳能电池。该结构的吸收在 300-1700 nm 的宽带波长范围内以数值方式获得。研究了层厚和金属纳米线横截面形状的影响。结果表明，矩形纳米线系统的吸收在以下范围内超过 90%$560-1180n米$. 此外，吸收范围为$300-1200\text{ 纳米}$当纳米线的横截面为半圆形时，超过 90%。这种在可见光区的高吸收可能有助于设计等离子体太阳能电池。
