Advances in laser technology have enabled ultra-high-speed ultra-precise processing, thus expanding potential applications to the semiconductor, medical, and photovoltaic industries. In particular, laser scribing technology has been applied to the production of shingled solar modules. In this work, we analyze the effect of laser scribing conditions, e.g., scribing depth, on the characteristics of the resulting divided solar cells. When the scribing depth was greater than 100 ㎛, the solar cells were well separated. In addition, the desired scribing depths were reached in fewer scans when the laser spot overlap was 100%. The efficiency of the divided cells decreased due to the high series resistance at scribing depths of less than 100 ㎛. However, at scribing depths of approximately 100 ㎛, the series resistance was low and efficiency reduction was minimized.
