In this paper, we present our investigation of the optical and electrical characteristics of silicon solar cells using silicon nanowire, silicon nanocone, silicon nanopillar, and silicon nanopillar/silicon nitride structures, which were obtained by the Ag-assisted electroless etching method and ICP etching with extreme ultraviolet lithography. We introduced the formation mechanism for four kinds of solar cells. We simulated the absorption of four structures for different parameters. Furthermore, we also performed current density-voltage (-) characterization of the samples with silicon nitride, which exhibited an improvement of the power conversion efficiency (PCE) in contrast to the samples without silicon nitride. It was found that the properties of trapping light for silicon nitride had a prominent impact on the improvement of the PCE in the silicon nanopillar solar cells.
在本文中，我们展示了对使用硅纳米线、硅纳米锥、硅纳米柱以及硅纳米柱/氮化硅结构的硅太阳能电池的光学和电学特性的研究，这些结构是通过银辅助化学蚀刻法以及结合极紫外光刻的电感耦合等离子体蚀刻获得的。我们介绍了四种太阳能电池的形成机制。我们针对不同参数模拟了四种结构的光吸收情况。此外，我们还对含氮化硅的样品进行了电流密度 - 电压（-）表征，与不含氮化硅的样品相比，含氮化硅的样品的功率转换效率（PCE）有所提高。结果发现，氮化硅的光捕获特性对硅纳米柱太阳能电池中PCE的提高有显著影响。
