Abstract: The present invention relates to a shingled solar cell panel for producing a string in which a plurality of strips are partially overlapped with each other, and for electrically connecting the string and the string, and a method for producing the same, the method comprises providing a wafer made of a HIT in which a plurality of conductive layers are formed on upper and lower portions thereof, respectively, forming an adhesive layer by applying a conductive adhesive on the upper conductive layer, dividing the wafer on which the adhesive layer is formed into a plurality of strips, forming a string by overlapping a lower conductive layer of another strip on an area where an adhesive layer is provided among the divided strips. Accordingly, the upper conductive layer and the lower conductive layer of each of the plurality of strips can be configured to be electrically bonded via only the adhesive layer to provide a shingled solar cell panel at low cost.
