Power from the sun

Fraunhofer-Institut für Solare Energiesysteme ISE


The Fraunhofer Institute for Solar Energy Systems ISE conducts research on the technology needed to supply energy efficiently and on an environmentally sound basis in industrialised, threshold and developing countries. To this purpose, the Institute develops systems, components, materials and processes in the areas of the thermal use of solar energy, solar building, solar cells, electrical power supplies, chemical energy conversion, energy storage and the rational use of energy.

The Institute's work ranges from fundamental scientific research relating to solar energy applications, through the development of production technology and prototypes, to the construction of demonstration systems. The Institute plans, advises and provides know-how and technical facilities as services.

New world record for solar cell efficiency at 46%
Dec 01, 2014

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.

Decentralized Intelligence for the Smart Grid – Fraunhofer ISE Launches New Spin-Off Company, Enit Systems

December 1, 2014

Enit Energy IT Systems GmbH is the latest spin-off of the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg. The young company develops and markets monitoring and control systems for decentralized energy systems like combined heat and power plants, photovoltaic systems or industrial consumers. These systems help customers gain more transparency about their electricity, heat and gas consumption. In addition, the company’s products enable intelligent system control and more efficient operation. The internally developed technology, called OpenMUC, adapts itself to the customer’s system and remains flexible for adaptions in the future. Since September 1, 2014 the company Enit Systems is up and running in Freiburg.
