1. A module layer embodied as a structural unit, comprising:
a plurality of elementary cells, which are electrically connected to one another in series circuits and parallel circuits,
wherein the cells of the module layer in a tray are positioned on a base element of the tray and are enclosed by an outer frame that is embodied as a heat sink and constitutes a rim of the tray, the outer frame has a seal, and in a central region of the base element, the tray has a section of a central shaft into which bus bars protrude, which produce a conductive connection with the cells of the respective module layer.
