采用纳米压印光刻和Bosch腐蚀方法制备了高度有序的硅纳米线。生长多晶硅壳以形成径向p-n结。为了增强其抗反射性能和导电性，在SiNWs太阳能电池上沉积薄ITO层，然后引入微栅电极以最小化金属面积以最大化载流子收集。最后，使用较短的纳米线来减少表面复合并实现10.5%的效率。这项工作有望显示一些可能的技术，以提高硅纳米结构太阳能电池的性能。
Highly ordered silicon nanowires (SiNWs) were fabricated by nanoimprint lithography and Bosch etching methods. A polycrystalline silicon shell was grown to form a radial p-n junction. To enhance its anti-reflection properties and conductivity, a thin ITO layer was deposited on the SiNWs solar cell, then a micro-grid electrode was introduced to minimize the metal areas to maximize carrier collection. Finally, shorter nanowires were used to reduce surface recombination and achieve an efficiency of 10.5%. This work is expected to show some possible techniques to improve the performance of silicon nanostructure solar cell.
