优化设计太阳电池的电极图形可以获得高的光电转换效率。文中以实例介绍了晶体硅太阳电池上丝网印刷电极的优化设计,讨论了电池的功率损耗与扩散薄层电阻及细栅线宽度的关系,在原始设计的基础上设计出了理想尺寸的太阳电池栅线。经过优化改进的太阳电池可降低由电极设计引起的总功率损失,并且提高了电池片的光电转化效率。%The electrode pattern of the optimal design for the solar cell can get the high photoelectric conversion efficiency. The optimal design of the screen-printed electrode in the crystalline silicon solar cell is introduced with the example, and the relation among the power loss in the solar cell, the diffusion sheet resistance and the width of the thin grid line is discussed. On the basis of the original design, the ideal solar cell grid line is designed. The optimal solar cell can reduce the total power loss caused by the electrode design, and increase the photoelectric conversion efficiency of the cell.
