Abstract: Disclosed are a high-efficiency and high-reliability PERC solar cell and a front electrode thereof, and a manufacturing method, which belong to the solar cell technology. Busbars of the front electrode of solar cell of the present disclosure includes fine busbars and solder joints distributed on the fine busbars at intervals. Each fine busbar between adjacent solder joints includes a straight fine busbar connecting the two solder joints, and side fine busbars located on both sides of the straight fine busbar respectively. In the method for manufacturing the front electrode, the busbars and the fingers are printed by a step-by-step printing process.
