A solar cell and a solar cell module are disclosed. The solar cell module includes a plurality of solar cells each including a semiconductor substrate and first and second electrodes on the semiconductor substrate, the first and second electrodes being alternately positioned in a first direction and extended in a second direction intersecting the first direction, a first conductive line extended in the first direction to intersect the first and second electrodes, connected to the first electrode by a first conductive layer, and insulated from the second electrode by an insulating layer, and a second conductive line positioned in parallel with the first conductive line, connected to the second electrode by the first conductive layer, and insulated from the first electrode by the insulating layer.
