FRONT-SIDE ELECTRODE STRUCTURE OF SOLAR CELL SHEET AND FABRICATION METHOD THEREFOR

WIPO Patent Application WO/2014/012432

A1

The present invention relates to a front-side electrode structure of a solar cell sheet and a fabrication method therefor. The structure comprises a cell sheet and a conducting wire, the conducting wire being coated with a conducting paste and adhered to a surface of the cell sheet. A method for fabricating the front-side electrode structure of a cell sheet is also involved, comprising: coating a conducting paste onto the surface of a conducting wire; adhering the conducting wire coated with the conducting paste onto the cell sheet; and placing the fabricated cell sheet into a drying and sintering furnace for drying and sintering. The advantages of the front-side electrode structure of a solar cell sheet and the fabrication method therefor of the present invention are that the width of a front-side fine grid line of a solar cell is reduced greatly, the electric conductivity of the fine grid line is improved and the light receiving surface is increased, thus improving the conversion efficiency of the cell; and the usage amount of a conducting paste in the fabrication process is decreased, thus reducing the electrode fabrication cost of a solar cell sheet.
