The development of renewable energies offers enormous future market chances in a world market, which is influenced by environmental challenges and scarcity of raw materials. Vacuum pumps and vacuum systems are used in all manufacturing steps within the production of solar modules. In this application the advantage of the vacuum engineering shows up: the large process purity. The chip production works within a high vacuum range from 10-3 to 10-7 mbar. Only in this pure atmosphere circuits can be produced with high precision.

The photovoltaic cells are laminated under vacuum. Innovative Vacuum pumps of JUST VACUUM make fast cycle times possible at high suction property. The high vacuum is necessary for an optimal gluing of the laminate to the finished solar module. The central vacuum systems of JUST VACUUM are used to automatize all steps within the production from solar cells. They provide the necessary negative pressure for all applications, e.g. for laminating or for the handling of the glass plates.

Example of use:

Vacuum system consisting for a prominent producer of photovoltaic cells for the execution of material tests in the UHV range of:

• UHV chamber with pipeline system, feedthroughs and valves in CF-execution
• Turbomolucular pump
• Sample chamber
• heatable sample holders
• Heating system
• Measuring system
