초록

MBB (multi-busbar) technology is a module technology to achieve high power, and the use of a number of thin circular metal wires increases light-receiving capacity and reduces resistance. In the process of interconnection using a wire, the stress of the cell increases depending on the degree of coupling between the wire and the cell and the degree of damage caused by heat, or the mobility of current decreases due to poor bonding. The degree of such loss is affected by IR lamp, hot plate temperature and wire thickness. In addition, the values of contact resistance were compared and analyzed to analyze the cause of the decrease in electrical characteristics. In this study, process condition optimization was carried out through peeling test, SEM analysis, EL test, and pre/post bonding efficiency characteristic analysis of the bonded cell according to process conditions, compared the contact resistance.
