Herein we report the demonstration of electrochemical deposition of silicon p-n junctions all in molten salt. The results show that a dense robust silicon thin film with embedded junction formation can be produced directly from inexpensive silicates/silicon oxide precursors by a two-step electrodeposition process. The fabricated silicon p-n junction exhibits clear diode rectification behavior and photovoltaic effects, indicating promise for application in low-cost silicon thin film solar cells.
在此，我们报告了在熔融盐中电化学沉积硅 p-n 结的演示。结果表明，通过两步电沉积工艺，可以直接从廉价的硅酸盐/氧化硅前体制备出具有嵌入式结形成的致密、坚固的硅薄膜。所制备的硅 p-n 结表现出明显的二极管整流行为和光伏效应，这表明其在低成本硅薄膜太阳能电池中的应用具有很大的潜力。
