摘要： This disclosure describes various structures, devices, and arrangements that replace a PSA used to hold shingled cells together with an adhesive film. For example, in an aspect, the present disclosure is directed to a shingled arrangement of photovoltaic (PV) cells. In some aspects, the shingled arrangement of PV cells may include a first PV cell, a second PV cell, and an adhesive film placed between a backside the first PV cell and a front side of the second PV cell. The adhesive film may be thermally bonded to the first PV cell and to the second PV cell after the application of localized heat and pressure and holds the first PV cell and the second PV cell together. Additionally, a bus bar of the second PV cell may be electrically connected to the first PV cell by a conductive via formed through the adhesive film.
