Fraunhofer researchers receive the Franco-German Business Award 2011
Date:12/6/2011

The photovoltaics industry is booming more and more solar modules are appearing on rooftops, and even large-scale solar power plants are increasingly feeding power into the grid. Multi-junction solar cells are particularly efficient in this regard: they can achieve efficiencies of up to 43 percent - twice the level of conventional solar cells made of crystalline silicon. The trick: they consist of several semi-conductor layers that combine to transform the entire spectrum of sunlight into electrical energy. This technology is used in concentrator photovoltaics. There, lenses focus the light of the sun 500 times onto tiny solar cells. These concentrator systems produce solar electricity on a large scale, particularly in solar power plants located in areas rich in sunlight. Among the producers of these plants is SOITEC Solar GmbH, in Freiburg, Germany, a former spinoff of the Fraunhofer Institute or Solar Energy Systems ISE.

The multi-junction solar cells themselves consist of some 30 semi-conductor layers built up, layer for layer, on ultra-pure crystals of germanium or gallium arsenide. These materials are very costly, however. In a joint Franco-German project, researchers at ISE in Freiburg and their colleagues from the Carnot-Institut Laboratoire d'lectronique des technologies de l'information CEA-LETI in Grenoble, France, are working to develop new substrates for multi-junction solar cells. The new technology replaces the expensive materials with reusable substrates. Whereas up until now the solar cells had to remain in place atop the germanium or gallium arsenide crystals, the solar cells are now removable from the new substrate which is recycled several times. This way, the cost of producing solar cells can be reduced by up to 20 percent.

In the Solar-Bond project, two high-tech institutes have combined their skills," according to Dr. Frank Dimroth, Head of Department III-V - Epitaxy and Solar Cells at Fraunhofer ISE. CEA-LETI is a lea
