In this paper, micro-sized silver particles were prepared using a simple chemical approach without adjusting the pH of the solution, and oleylamine as a capping agent was described to promote the dispersion of the silver particles. The effects of temperature, feeding time and stirring speed on the morphology and size distribution of silver particles were discussed. The optimal reaction parameters (35 °C, 45 min, 300 rpm) for large scale industrial production were selected to obtained optimal silver particles for preparation of the silver paste for poly-crystalline silicon solar cells. The photoelectric conversion efficiency of the solar cells made with silver paste by using the silver particles can reach 18.623%, which is similar to the industrial production of solar cell made with commercial silver paste. This work contributes to the development of the synthesis of highly disperse silver particles used in solar cells in large scale industrial productions.
在本文中，采用一种简单的化学方法制备了微米级银颗粒，无需调节溶液的pH值，并描述了使用油胺作为封端剂来促进银颗粒的分散。讨论了温度、进料时间和搅拌速度对银颗粒形态和尺寸分布的影响。选择了大规模工业生产的最佳反应参数（35℃、45分钟、300转/分钟），以获得用于制备多晶硅太阳能电池银浆的最佳银颗粒。使用这些银颗粒制成的银浆制备的太阳能电池的光电转换效率可达18.623%，这与使用商业银浆进行工业生产的太阳能电池相似。这项工作有助于大规模工业生产中用于太阳能电池的高度分散银颗粒合成的发展。
