Abstract: In a method and system consisting of a photovoltaic module and a connection housing or a junction box, wherein the photovoltaic module comprises at least one solar cell which is coupled at a rear side to an electrically conductive and structured layer for conducting away the electrical energy generated in a solar cell, and, furthermore, at least one transparent carrier layer and a covering layer are provided, wherein the electrically conducting layer can be contact-connected to connections of the connection housing, it is proposed that connections or connection elements of the connection housing can be coupled directly to partial regions having different polarities of the conducting layer via at least one through-opening in the covering layer, as a result of which contact-connection of a photovoltaic module to connection elements of a connection housing can be obtained in a simple and reliable manner.
