【 英文摘要 】The invention relates to the field of solar cells and particularly discloses an electrode structure on the back of a solar cell and a manufacturing method thereof. The electrode structure comprises a silicon chip and a metal wire which are adhered through electrocondution slurry, and the electrocondution slurry and the metal wire are formed into an integrated conductor through the steps of drying and sintering. According to the electrode structure on the back of the solar cell and the manufacturing method, an electrode or a point electrode, which is formed by the metal wire, can replace a face electrode on an original silicon chip. A good passivating layer and a reflecting layer can be manufactured in a non-electrode area, the surface recombination speed can be reduced by the good passivating, the infrared spectral response can be improved by the good reflection, and accordingly the conversion efficiency of the solar cell is improved.
