| 摘 要： | 首先从热力学角度讨论减少太阳能光伏结构效率损失,特别是光学熵损失的原理和途径,然后介绍半导体纳米线阵列在降低材料使用率的同时有效实现陷光和降低发射角的结构设计,其中由直径渐变纳米线形成的非周期阵列具有可见到近红外宽波段的导模共振陷光能力,同时极低的发射角大幅度地抑制了自发辐射引起的光子损失,成为有望突破Shockley-Queisser转换效率极限的光伏结构.

| Abstract: | In this paper, a thermodynamic analysis on current photovoltaics wsa given within the Shockley-Queisser model. Then the latest progresses of designing semiconductor nanowire arrays are introduced to achieve effective light trapping and reduced emission angle. Among them, non-uniform nanowire arrays with gradient shapes hold both advantages of ultralow emission angle and light trapping, therefore has attracted much research interest toward ultrahigh efficiency of solar energy conversion from visible to near-infrared wavelength. |

| Keywords: | solar cells visible to near-infrared omnidirectional absorbtion emission angle limit non-uniform nanowire arrays |
