Method for producing solar cell string, and solar cell string

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

• preparing a plurality of small cell pieces by forming a first collector electrode by applying a first collector electrode material comprising a first metal component and a first resin component to one surface of a semiconductor substrate and curing the first collector electrode material, and forming a second collector electrode by applying a second collector electrode material comprising a second metal component and a second resin component softer than the first resin component to an other surface of the semiconductor substrate and leaving the second collector electrode material uncured;
• and
• curing the second collector electrode material after each two adjacent ones of the plurality of small cell pieces are partially overlapped with each other to allow the first collector electrode of one of each two adjacent small cell pieces to overlap the second collector electrode of an other one of each two adjacent small cell pieces.
