Solar cell and solar cell module

A solar cell is disclosed. The solar cell includes a substrate of a first conductive type; a plurality of emitter layers having a second conductive type opposite the first conductive type, the plurality of emitter layers positioned in a first surface of the substrate and extended in a first direction in the first surface of the substrate; a plurality of surface field layers having the first conductive type more heavily doped than the substrate, the plurality of surface field layers positioned in the first surface of the substrate and extended in the first direction in the first surface of the substrate; a passivation layer positioned on the first surface of the substrate and including a plurality of first openings exposing portions of each of the plurality of surface field layers and a plurality of second openings exposing portions of each of the plurality of emitter layers; a plurality of first electrodes positioned in the plurality of first openings and contacting the plurality of surface field layers; a plurality of second electrodes positioned in the plurality of second openings and contacting the plurality of emitter layers; a plurality of first conductive members positioned on the plurality of first electrodes; and a plurality of second conductive members positioned on the plurality of second electrodes.
