摘要： Disclosed is solar cell, a photovoltaic module, and a method for manufacturing a photovoltaic module. The solar cell includes a substrate, first busbars and second busbars arranged on the substrate, first fingers connected to the first busbars, and second fingers connected to the second busbars. The first busbars and the second busbars have opposite polarities. The first fingers have a same polarity as the first busbars, and the second fingers have a same polarity as the second busbars. The substrate is provided with busbar pits. At least part of the first and second busbars are located in the busbar pits. Depths of the busbar pits range from 30 µm to 50 µm. Along a thickness direction of the substrate, ratios of the depths of the busbar pits to heights of the first busbars and/or the second busbars range from 10:3 to 6:5.
