本文在Shockley-Queisser模型下，对电流光电转换进行了热力学分析。然后介绍了半导体纳米线阵列设计的最新进展，以实现有效的光捕获和减少发射角。其中，具有梯度形状的非均匀纳米线阵列兼具超低发射角和陷光的优点，因此在可见光到近红外波段的太阳能转换中的应用成为研究热点。
In this paper, a thermodynamic analysis on current photovoltaics is given within the Shockley-Queisser model. Then the latest progresses of designing semiconductor nanowire arrays are introduced to achieve effective light trapping and reduce emission angle. Among them, non-uniform nanowire arrays with gradient shapes hold both advantages of ultralow emission angle and light trapping, therefore which have attracted much research interest toward ultrahigh efficiency of solar energy conversion from visible to near-infrared wavelength.
