Abstract

A solar cell and a photovoltaic module are provided. The solar cell includes a substrate having first edges and second edges; two first main electrodes, where each first main electrode is close to a corresponding first edge and includes a plurality of first sub-connection pads and a first connection wire; and at least two second main electrodes, where the at least two second main electrodes are disposed between the two first main electrodes, where each of the at least two second main electrodes includes a plurality of second sub-connection pads and a second connection wire, where a first pitch between a respective first main electrode and a second main electrode adjacent to the respective first main electrode is not equal to a second pitch between adjacent second main electrodes.
