Abstract: A solar cell and manufacturing method of back electrodes thereof are disclosed. The method includes a step of implementing a screen printing process to a semiconductor substrate. The method also includes a step of measuring a deviation which exists between laser ablation recesses and back electrodes in the screen printing process. The method further includes a step of adjusting the distance between the laser ablation recess and the back electrode according to the deviation. After adjusting, a deviation between laser ablation recesses and back electrodes will be controlled to a narrower range when the screen printing process is implemented to another semiconductor substrate. Thus, the defect is caused by the back electrodes incompletely covering the laser ablation recesses can be improved significantly.
