Hybrid Storage Offers Great Potential

Fraunhofer ISE has successfully tested a new concept called “hybrid storage.” In an agent-based operating system (ABOS), thousands of batteries and heat storage systems are aggregated to a virtual storage system. As decentralized control systems the agents coordinate the individual local storage operation. The storage capacity is aggregated for an integrated distribution grid operation. The agent-based operation-system has been developed and tested within the SmartEnergyLab at Fraunhofer ISE.

New world record for solar cell efficiency at 46%

French-German cooperation confirms competitive advantage of European photovoltaic industry

A new world record for the direct conversion of sunlight into electricity has been established. The multi-junction solar cell converts 46% of the solar light into electrical energy and was developed by Soitec and CEA-Leti, France, together with the Fraunhofer Institute for Solar Energy Systems ISE, Germany. Multi-junction cells are used in concentrator photovoltaic (CPV) systems to produce low-cost electricity in photovoltaic power plants, in regions with a large amount of direct solar radiation. It is the cooperation’s second world record within one year, after the one previously announced in September 2013, and clearly demonstrates the strong competitiveness of the European photovoltaic research and industry.
