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.

Partners from Industry and Research Develop a CSP Yield Assessment Manual

November 27, 2014

The Fraunhofer Institute for Solar Energy Systems and a group of partners from research and industry are cooperating to develop a guideline for determining the power yield of solar thermal power plants as part of the CSPBankability project, an initiative funded by the German Ministry of Economics and Energy (BMWi). An accurate definition of the expected electricity yield is an essential criterion in the financing of a power plant project.

Snow Globe Coating: What Do Snowballs and Solar Cells Have in Common?

Snow falls gently on a fairytale landscape, covering it with white flakes. The well-known concept behind the miniature snow globe was developed in Vienna in the 19th century. A similar principle, called “Snow Globe Coating” is now being applied to solar cells to increase their efficiency. This method was developed by the staff scientist Dr. Angelika Basch at the University of Applied Sciences Upper Austria in Graz. Currently it is being further developed in cooperation with the Fraunhofer Institute for Solar Energy Systems ISE in Freiburg.

Solar Cell Contacts From Tubes – Innovative Fine Line Metallization Technology Promises Higher Efficiency Values
Oct 16, 2014

Together with industrial partners MERCK, HERAEUS and ASYS, researchers from the Fraunhofer Institute for Solar Energy Systems ISE have developed innovative new materials and contactless techniques for applying ultrafine, homogeneous contact fingers to solar cells. This ‘dispensing’ technology can be easily integrated into conventional silicon solar cell production lines where it replaces screen printing as the method of applying front side metallization: Consequently material usage is reduced, contact fingers are thinner and more of the semiconductor surface area is exposed to sunlight, which results in increased current collection and relative improvements in efficiency of around two percent. The new technology can also be used to optimize further production steps in solar cell manufacture.
