BUSBAR-LESS SHINGLED ARRAY SOLAR CELLS AND METHODS OF MANUFACTURING SOLAR MODULES

Abstract:

A method of forming a solar module. The method includes etching a solar cell, singulating the cell to form strips, and depositing a conductive adhesive on at least one portion of the singulated strips. The strips are then arranged with the conductive adhesive in a shingled manner to form strings of strips such that a portion of each strip overlaps with a portion of the next with the conductive adhesive forming a bond between adjacent strips. A plurality of strings are then connected electrically in parallel to form a set of strings, and a plurality of sets of strings are connected electrically in series. The sets of strings are encapsulated between a front glass and a backsheet and mounted in a frame to form a solar module.
