Electrode of a solar cell substrate

A solar cell includes a semiconductor substrate, a passivation layer, a back electrode layer, and several bus bars. The semiconductor substrate has an upper surface and a lower surface opposite with each other. The passivation layer is disposed at the lower surface and includes several blank regions and several first openings. Each first opening is not located in the blank regions. The bus bars are respectively disposed on the blank regions of the passivation layer. The back electrode layer is disposed on the passivation layer and electrically connected to the semiconductor substrate through the first openings. The back electrode layer includes several second openings corresponding to the bus bars, respectively. The size of each second opening is not greater than the size of the corresponding bus bar, so that the back electrode layer is electrically connected to the bus bars.
