Abstract
The present application relates to a solar cell, a method for manufacturing the same, a photovoltaic module and a photovoltaic system. The solar cell includes: a substrate (), including a first surface (S) and a second surface (S) being opposite to each other, wherein the first surface (S) has a first region (A) and a second region (B) adjacent to each other in a first direction; a passivating contact layer (), located in the first region (A) of the first surface (S); a polysilicon layer () located on at least a part of a surface of the passivating contact layer () away from the substrate (); the passivating contact layer () including a first tunneling layer () and a first doped layer (), the first tunneling layer () and the first doped layer () being sequentially stacked on the first region (A) of the first surface (S) of the substrate () in a direction away from the second surface (S); and a first passivation layer (), located on a surface of the polysilicon layer () away from the passivating contact layer () and on the second region (B) of the first surface (S).
