Abstract

Disclosed are a solar cell and a photovoltaic module. In the solar cell, first and second conductive doped portions are arranged in an edge region of a first surface of a substrate. Each first conductive doped portion includes a first doped portion and second doped portions disposed on two opposite sides of the first doped portion, and a dopant concentration of the first doped portion is greater than that of the second doped portions. A passivation layer is disposed on the first surface. The second edge fingers are disposed on the second conductive doped portions respectively. Each first edge finger includes a first sub-finger and a second sub-finger, disposed on the second doped portions respectively. The second sub-finger is connected to the first sub-finger via the first doped portion. An edge busbar disposed on the passivation layer and on the first doped portion is connected to the second edge fingers.
