Abstract

This paper and the rear passivation experiment was local back surface field Nd:$YVO_4$ green laser and the experiment was used performed to screen printing. Laser power 100%, with a fixed frequency for 60kHz Current of 29A and 30A were tested in two conditions. The point contact distances of 0.2mm, 0.4mm, 0.6mm, 0.8mm and 29A and 30A current conditions, it was found that is suitable for 0.4mm.
