Abstract
Provided is a photovoltaic solar cell, a solar cell module and a manufacturing process. The photovoltaic solar cell includes a silicon substrate, and a passivation layer located on at least one surface of the silicon substrate. An electrode, an electrode pad and an extension line are printed on at least one surface of the silicon substrate. The electrode includes a busbar and a finger crossed with each other, and the finger is in contact with the silicon substrate. Two ends of the extension line are respectively connected to the busbar and the electrode pad, and the extension line is in contact with the silicon substrate.
