Solar cell string and photovoltaic module

A photovoltaic module, comprising a solar cell string that comprises:

• a solar cell, the solar cell comprising:
• a substrate;
• a plurality of first doped layers on a first surface of the substrate;
• a plurality of second doped layers on the first surface of the substrate, wherein the plurality of first doped layers and the plurality of second doped layers extend along a first direction and are alternately arranged along a second direction intersecting with the first direction, wherein a first isolation region is provided between a first doped layer of the plurality of first doped layers and a second doped layer of the plurality of second doped layers that is adjacent to the first doped layer;
• first fingers on the plurality of first doped layers;
• and
• second fingers on the plurality of second doped layers, wherein the first fingers and the second fingers extend along the first direction;
• first connecting members, wherein the first connecting members extend along the second direction and are connected to the first fingers;
• and
• second insulating blocks in a first region of the first surface, wherein the second insulating blocks are at intersections of the first connecting members and are in a one-to-one correspondence with the second fingers, wherein at least a part of the second insulating blocks extend along the second direction into adjacent first isolation regions, and wherein the second insulating blocks cover side surfaces of corresponding second doped layers.
