Solar cell with connecting sheet, solar cell module, and fabrication method of solar cell with connecting sheet

摘要

A method of fabricating a solar cell with a connecting sheet includes a fixing step of bonding at least a portion of a peripheral region of a back electrode type solar cell (8) to a connecting sheet (10). A method of fabricating a solar cell module includes the step of sealing the solar cell with a connecting sheet obtained by the method on a transparent substrate (17) by a sealing material (18). A solar cell with a connecting sheet has a first adhesive arranged between a back electrode type solar cell (8) and a connecting sheet (10), and a second adhesive arranged at at least a portion of a peripheral region of the back electrode type solar cell (8) to bond a back electrode type solar cell (8) with a connecting sheet (10). A solar cell module has the solar cell with a connecting sheet sealed on a transparent substrate (17) by a sealing material (18).

1. A method of fabricating a solar cell with a connecting sheet including a back electrode type solar cell including a semiconductor substrate where an impurity diffusion region for a first conductivity type and an impurity diffusion region for a second conductivity type are formed, an electrode for the first conductivity type formed at one face side of said semiconductor substrate corresponding to said impurity diffusion region for the first conductivity type, and an electrode for the second conductivity type formed at said one face side of said semiconductor substrate corresponding to said impurity diffusion region for the second conductivity type, and
a connecting sheet having an insulative base material, a wire for the first conductivity type arranged at said insulative base material, and a wire for the second conductivity type arranged at said insulative base material, said method comprising: applying a first adhesive to said back electrode type solar cell and/or said connecting sheet, arranging said back electrode type solar cell on said connecting sheet to sandwich said first adhesive therebetween such that said electrode for the first conductivity type of said back electrode type solar cell is arranged on said wire for the first conductivity type of said connecting sheet, and said electrode for the second conductivity type of said back electrode type solar cell is arranged on said wire for the second conductivity type of said connecting sheet, and fixing at least a portion of a peripheral region of said back electrode type solar cell to said connecting sheet.
