Method for connecting solar cell string

A method for connecting a solar cell string, the method comprising:

• forming a plurality of first collector electrodes on one surface of a solar cell;
• forming a plurality of second collector electrodes by applying a pasty second collector electrode material comprising a metal component and a synthetic resin component to portions of an other surface of the solar cell so as to be opposed to the respective ones of the plurality of first collector electrodes, wherein the plurality of first collector electrodes and the plurality of second collector electrodes each comprise a bus bar electrode;
• forming a plurality of dividing guidelines on the solar cell to allow the solar cell to be easily divided into a plurality of small cell pieces, wherein each of the plurality of dividing guidelines is formed between each two adjacent ones of the plurality of first collector electrodes formed on the one surface and between each two adjacent ones of the plurality of second collector electrodes formed on the other surface;
• cutting the solar cell along the plurality of dividing guidelines to divide the solar cell into the plurality of small cell pieces each having each of the plurality of first collector electrodes and each of the plurality of the second collector electrodes;
• overlapping the plurality of small cell pieces so as to bring the bus bar electrode of each of the plurality of first collector electrodes and the bus bar electrode of each of the plurality of second collector electrodes into overlapping each other;
• and
• curing the pasty second collector electrode material after the plurality of small cell pieces are made to overlap.
