Manufacturing method of solar energy cell

The invention provides a manufacturing method of a solar energy cell. The manufacturing method includes the steps: providing a semiconductor substrate which is provided with a light receiving surface provided with an anti-reflective layer and a shady surface; then screen printing a plurality of first electrode patterns on the anti-reflective layer; sintering the first electrode pattern; and then etching part of the first electrode, to reduce width of the first electrode; then electroplating the same materials as the first electrode on the first electrode, to form a front electrode of the solar energy cell.
