By the experiment of SiN rear surface passivation solar cells, we made the rear surface point-contact electrode with diameter of 300um and space of 2mm using screen printing technology, and the Voc of silicon solar cells achieved to 628mv.
通过对背面氮化硅膜钝化电池进行实验,采用丝网印刷技术形成300um孔径、间距2mm的点接触电极,开路电压能达到628mv,为进一步实现背面钝化提供了必要的基础。
