摘要: 在全球“碳达峰”和“碳中和”目标的推动下,光伏产业已成为能源转型的关键领域,其中晶硅电池占据光伏市场95%以上的份额。然而,市面上的晶硅切削液存在硅粉分散排泄不足、润滑性欠佳、循环利用性弱等缺点,严重影响了晶硅的表面精度,阻碍了光伏行业的发展。本文旨在克服上述不足,探究离子液体改性切削液对晶硅表面质量的影响。实验结果表明,向市售切削液中添加1%(质量分数)1-甲基-3-辛基咪唑氯盐([OMIM]Cl)离子液体的改性切削液性能最好,其pH值为6.26,黏度降至64.39 mPa·s,表面张力低至24.07 mN/m,表面接触角最小,润湿渗透能力最强,与市售切削液相比,摩擦系数降低约60%,磨损量减少26.1%,在降低摩擦与提升晶硅表面质量方面表现良好,具有广泛应用前景。

Abstract: Driven by the global goals of carbon peak and carbon neutrality,the photovoltaic (PV) industry has become pivotal to energy transition,with crystalline silicon cells dominating over 95% of the PV market. However,commercially available crystalline silicon cutting fluids suffer from deficiencies such as inadequate dispersion and discharge of silicon powder,poor lubricity,and weak recyclability. These shortcomings severely compromise the surface precision of crystalline silicon and hinder the development of the photovoltaic industry. This study aims to overcome the aforementioned shortcomings of crystalline silicon cutting fluids by investigating the impact of different ion-liquid modified cutting fluids on crystalline silicon surface quality during the cutting process. Test results indicate that the modified cutting fluid,which incorporates 1% by mass of 1-methyl-3-octylimidazole chloride salt ([OMIM]Cl) as an ionic liquid into commercial cutting fluids,demonstrates the optimal performance. Its pH value is 6.26,the viscosity drops to 64.39 mPa·s,surface tension lowers to 24.07 mN/m,contact angle minimizes,and wetting penetration capability maximizes. Compared to the commercial cutting fluid,its friction coefficient decreases by over 60%,and wear volume decreases by 26.1%. It demonstrated excellent performance in reducing friction and enhancing crystalline silicon surface quality,offering broad prospects for widespread application.
