A solar cell module is discussed. The solar cell module includes a plurality of solar cells, an interconnector for electrically connecting the adjacent solar cells, and a conductive adhesive film for attaching the interconnector to the solar cell. Each solar cell includes a substrate, a back electrode part including a plurality of back electrode current collectors of an island shape, which are positioned on a back surface of the substrate and are separated from one another by a first distance along a first direction, and a back electrode which includes a plurality of openings exposing the back electrode current collectors and has a sheet shape covering the entire back surface of the substrate. The conductive adhesive film alternately includes a first portion contacting the back electrode current collector and a second portion contacting the back electrode based on the first direction.
