Abstract: A manufacturing method of an electrode of a solar cell is provided. The manufacturing method of the electrode of the solar cell includes following steps. A laser doping process is performed to form a selective emitter on a substrate. A laser marking process is performed to form alignment markers on the substrate. The laser doping process and the laser marking process are performed in a same process chamber. An electrode screen printing process is performed to form an electrode on the selective emitter according to the alignment markers. Relative displacement between the alignment markers and the laser doping area (the selective emitter) is avoided so as to reduce the error of the subsequent screen printing process.

Abstract: An apparatus for reducing etching marks on a solar cell surface includes an etching bath, an etchant-feeding pipe configured in the etching bath, and a bubble guiding device that covers the etchant-feeding pipe. The bubble guiding device guides bubbles discharged from the etchant-feeding pipe to move toward at least one end of the etchant-feeding pipe for reducing etching marks on the solar cell surface.
