| 中文摘要: |
| 随着晶硅太阳能电池制备技术的发展，对其导电银浆用银粉的形貌、分散性、表面性质和粒径分布等提出了更高的要求。除了提高银粉本身结构特性外，银粉的后处理是解决以上问题并能实现其应用的关键步骤。在分析国内外近20年来40余篇相关文献的基础上，总结了晶硅太阳能电极银浆用银粉的后处理方法，主要包括表面改性(化学改性法、机械复合法及原位生成粒子法)和银粉粒度分级处理(机械振动筛分级和气流分级)，并对上述方法的优缺点进行了总结分析与展望。 |
| 英文摘要: |
| With the development of preparation technology for crystalline silicon-based solar cells, higher requirements are proposed for the morphology, dispersion, surface properties and particle size distribution of silver powder. In addition, the post-processing of the silver powder is a key step to improve its performance and realize its application. Based on the analysis of more than 40 related literatures in the past 20 years, the post treatment methods of such silver powder are summarized. The methods mainly include surface modification (chemical modification, mechanical compounding and in-situ particle generation) and techniques for screening silver powder (mechanical vibrating classification and airflow classification). The advantages and disadvantages are discussed, and future development is prospected. |
