Increasing prices for energy and depletion of fossil fuels are driving forces behind the development and use of renewable sources of energy. A major challenge for the photovoltaic industry – and we are ready to meet this challenge! The Fraunhofer CSP contributes to ensuring that alternative energy can be offered at the same price as conventional energy.

For this purpose, we are combining the know-how of two institutes in Halle (Saale): the Fraunhofer Institute for Microstructure of Materials and Systems IMWS is specialized in optimizing and evaluating silicon process technologies und module integration. The largest European solar energy research institute Fraunhofer ISE offers its skills in manufacturing materials, in the development of photovoltaic cells and modules as well as analytical skills.

The Fraunhofer CSP provides expert advice, scientific know-how and high-tech equipment for various services. Get in touch with us!

The Fraunhofer CSP is a joint activity for Fraunhofer IMWS and Fraunhofer ISE.

Influence of Grain Boundaries on Strength of Multicrystalline Silicon Wafers

With a market share of nearly 66%, multicrystalline silicon (mc-Si) wafers are widely used substrates for the production of solar cells. However, besides the fact, that their production costs are lower than those for monocrystalline wafers, they also tend to have a lower mechanical strength. That reduced strength, which is substantially determined by cracks induced in the surface, leads to an earlier breakage and, consequently, to a reduced economic efficiency in manufacturing solar cells.
