(DE19834459-A1)      The method involves preparing a honeycomb cell structure (20) by joining two surface panels (24,26) to opposite opening sides of a honeycomb core (21). One panel has perforations (29) communicating with cavities (23) in the cells (22) of the core.    The core has at least a pair of perforations (28) in the walls of each of the cells or is made of a porous material. A solar battery unit (10) is mounted on the surface panel via a sheet of bonding material (31) and they are joined by applying heat and pressure while the air remaining in the gap between them is caused to flow into the cavities in the cells.    ADVANTAGE -   Eliminates air bubbles between the solar battery unit and the surface panel of the honeycomb structure, thereby increasing uniformity of the produced solar battery module. Allows thorough radiation of heat from the solar battery unit even when it is at a high temperature because the interface between the joining member and the solar battery unit communicates with the ambient air via the cavities. Allows sunlight to be converted into electrical energy with fully satisfactory efficiency. Alleviates the usual decline of electrical output due to rises in temperature.
