The interconnecting shingled solar cells method shows extremely high ratio active area per total area and has the excellent potential for high power PV (photovoltaic). Compared to the conventional module, it can have much more active area due to busbar-free structure. The properties of ECA (electrically conductive adhesives) are significant to fabricate the shingled array PV since it should be used in terms of electric and structural connection. Various ECA were tried and characterized to optimize the soldiering conditions. The open circuit voltage of shingled array cells showed a three-fold increase and efficiency was also increased by 1.63%. The shingled array cells used in CE3103WLV showed the highest power and in CA3556HF the lowest curing temperature and very fast curing time.
