The uniform distribution of silver nanoparticles on the surfaces of diamond-wire sawn multicrystalline silicon (mc-Si) is critical for the texturing of mc-Si by the Ag metal-assisted chemical etching method (Ag-MACE). In this study, an additive containing alkylphenol polyoxyethylene is developed to improve the Ag-MACE process. It enables an even deposition of the silver nanoparticles over the surface of the silicon wafer, so that the entire wafer surface can be uniformly textured with nanostructures. The experimental results show that the additive improves the appearance and performance of solar cells, including their reflectivity, efficiency, internal quantum efficiency and external quantum efficiency. Mass-produced mc-Si solar cells textured using Ag-MACE with this additive have achieved a maximum efficiency of 19.51%, compared with an efficiency of 19.16% for cells fabricated without the additive.

银纳米颗粒在金刚石线锯多晶硅（mc-Si）表面的均匀分布对于通过Ag金属辅助化学刻蚀方法（Ag-MACE）构造mc-Si至关重要。在这项研究中，开发了一种包含烷基酚聚氧乙烯的添加剂以改善Ag-MACE工艺。它能够使银纳米颗粒均匀地沉积在硅晶片的表面上，从而可以使整个晶片表面均匀地带有纳米结构。实验结果表明，该添加剂改善了太阳能电池的外观和性能，包括反射率，效率，内部量子效率和外部量子效率。使用Ag-MACE和这种添加剂制成的大量生产的mc-Si太阳能电池的最大效率为19.51％，
