Zusammenfassung:	Disclosed are a solar cell and a photovoltaic module. The solar cell includes a substrate, having a first surface, having a metal pattern region and a non-metal pattern region, a first passivation contact structure, located in the metal pattern region and including a first tunneling layer and a first doped conductive layer stacked in a direction away from the substrate, and a second passivation contact structure, including a second tunneling layer and a second doped conductive layer stacked in the direction away from the substrate, and having a first portion over the non-metal pattern region and a second portion over the first passivation contact structure, and a top surface of the first portion of the second passivation contact structure is not further away from the substrate than a top surface of the second portion of the second passivation contact structure.
