Abstract: Provided is a solar cell and a photovoltaic module. The solar cell includes a silicon substrate, and the silicon substrate includes a front surface and a back surface arranged opposite to each other. P-type conductive regions and N-type conductive regions are alternately arranged on the back surface of the silicon substrate. Front surface field regions are located on the front surface of the silicon substrate and spaced from each other. The front surface field regions each corresponds to one of the P-type conductive regions or one of the N-type conductive regions. At least one front passivation layer is located on the front surface of the silicon substrate. At least one back passivation layer is located on surfaces of the P-type conductive regions and N-type conductive regions.
