Abstract
The high density module (HDM) has advantages for its larger active area and smaller current density. This new way of making a photovoltaic (PV) module method has benefit for increasing module power with the same installed area. Because HDM consisted with serially connected PV strings, loss of strings during the fabrication process can increase the overall production cost.1-2 This study investigates the rework conditions of the shingled strings with electrically conductive adhesives (ECA). By heating the electrically connected area of a fabricated string, cured area become soft and a string can be detached for the rework process. After rework process, a refabricated string showed 5~10% increased output power compared to before rework process and reached to the 90~95% output power compare to the undamaged strings.
