Apart from cost-saving generation of electricity, specialized modules fulfill further application-specific tasks. At the Fraunhofer CSP we develop new processes and products for these specific applications.
Architecturally demanding solutions and the integration of solar cells into structures like car tops or roofings, require the adjustment of the photovoltaic elements to the respective structure in particular. Among them are, above all, the lamination of brittle solar cells on convex or curved substrates. In our current work we are concerned with the development of adjusted manufacturing procedures in order to embed brittle, crystalline solar cells on top of convex structures. The evaluation of module quality then proceeds by means of electroluminescence and power measurement, revealing that especially the type of the solar cells used has a decisive influence on the lamination quality.
A special focus is set on lightweight construction modules. Here, we optimize the lightweight of the modules, i.e. the value which reports what power can be achieved relative to the weight of the module [W/kg].
