摘　　要：多次喷印是提高太阳电池效率的主要方法之一,但是多次喷印栅线展宽是此技术遇到的难点之一.文中以不增加印刷材料成本和栅线电阻值为前提,提出采用变墨滴体积多次喷印工艺方案.研究结果表明,采用变墨滴体积多次喷墨印刷技术能够降低太阳电池的栅线面积占太阳电池有源区域面积的比,能使光电转换效率处于13％～20％的硅太阳电池的光电转换效率增加0.41％～0.64％.Multi-pass ink-jet printing is one of the main ways to improve the efficiency of solar cells. However, grid line width broadening is one of the dit]~cult points of this technology. In order not to increase the cost of printing materials and grid line resistance, the multi-pass ink-jet printing process with variable volume drops was put forward. The results showed that the multi-pass ink-jet printing process with variable volume drops could reduce the ratio between the grid line area and the active area of the solar cell, and could improve the conversion efficiency of the silicon solar cell with efficiency between 13%-20% by 0.41%-0.64%.
