"Terrestrial solar cell generator"

The innovation concerns a terrestrial solar cell generator, its solar cells and solar cell connectors to protect against harmful environmental influences are surrounded on all sides by a material, preferably by a single material. 05

From DE-OS 24 45 642 a terrestrial solar cell generator is known whose solar cells are protected against harmful environmental influences in that they are on all sides together with their connecting elements are surrounded by a single material. Glass fiber reinforced plastics, thermoplastics or glass come into play as materials Question.

To counteract the terrestrial solar cell generator mentioned at the beginning To make weathering and mechanical damage more resistant, it is known from DE-OS 27 09 741, the surfaces the plastic cover with a weather-resistant film is sufficient Cover adhesive strength. Such a film can for example be made of polyvinyl fluoride or polyvinylidene fluoride exist.

The known terrestrial solar cell generators have in common that their mechanical stability as well as their Hail resistance is relatively low. These properties can be achieved through the use of special Shaped frame made of metal or other materials can be improved, but this is very expensive.

The innovation is therefore based on the task of providing a terrestrial solar cell generator with improved mechanical stability and improved hail resistance.

The object is achieved according to the invention in that the back of one of the solar cells of the solar cell generator containing GRP embedding is laminated onto a metal sheet.

In a further development of the innovation it is proposed that an aluminum sheet be used as the metal sheet.

Another embodiment of the innovation is that the front of the GRP embedding with a weather-resistant film, for. B. is covered from polyvinyl fluoride or polyvinylidene fluoride.

Advantages of the innovation result from the increase in the mechanical stability with respect to a mechanical one simplified additional framing. Framing is not necessary, especially for smaller units. This is above all Interesting for a military application in which terrestrial solar cell generators are designed to be mechanically foldable.

A solar cell generator can for example have an aluminum sheet 1 mm thick, 240 mm wide and 240 mm long. Before the solar cell generator on this sheet

is laminated on, the aluminum sheet must be pretreated. The aluminum sheet is first sanded with alcohol cleaned and primed. Only then does the lamination take place of the solar cell generator, which consists of a layer of Pal 50 - 70, of two layers of glass under and two layers of glass over the solar

cell module and a fine layer of Pal 50-70 can.
