Abstract

Provided are a solar cell and a photovoltaic module. The solar cell includes: a silicon substrate; a passivation layer provided on a surface of the silicon substrate; a first electrode conductor at least partially arranged on the passivation layer and including a body portion and protruding portions located on two ends of the body portion; and a second electrode conductor at least partially arranged on the passivation layer and at least partially overlapping with the protruding portions. A length of each of the protruding portions in a width direction of the body portion is greater than a width of the body portion.
