Einseitige Inline-Kupferabscheidung auf Siliciumsolarzellen mit lichtinduzierter Galvanik

Elektrochemische Prozesse zur Kontaktierung von Solarzellen werden am Fraunhofer ISE bereits seit mehreren Jahren verfolgt. Sie sind schnell, kostengünstig und laufen bei niedrigen Temperaturen ab. Bereits relativ etablierte Verfahren wie der galvanische Vollaufbau von Solarzellenkontakten aus Nickel, Kupfer und Zinn stehen unmittelbar vor der Marktreife. In der gezeigten industrienahen Anlage zur Kupferabscheidung werden diese Verfahren durch das Fraunhofer ISE gemeinsam mit seinen Industriepartnern für erste Kunden bemustert. Daneben erforscht das Fraunhofer ISE auch innovative Verfahren wie das elektrochemische Strukturieren von Aluminium. Unsere Expertise bezüglich der elektrochemischen Gegebenheiten in Kombination mit Prozesstechniken führte hier zur Idee eines vollständig neuen Strukturierungsansatzes, der für diverse fortschrittliche Zellkonzepte die Möglichkeit zur Metallstrukturierung bei niedriger Temperatur mit nur einem einfachen Prozessschritt bietet.

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.

»Solar for All« contest focuses on solar village and mini-grid solutions – Fraunhofer ISE and Canopus Foundation start second edition of the award
Jul 14, 2015

Solar power gained from photovoltaics (PV) will soon be the cheapest form of electricity in many regions of the world, as a recent study on long-term scenarios by Fraunhofer ISE on behalf of Agora Energiewende shows. In sunnier regions, for applications in rural areas, one kilowatt hour (kWh) gained from solar energy already today is cheaper than a kWh produced by a diesel system, which is due to the fast growing global market for PV. In this context, the Fraunhofer Institute for Solar Energy Systems ISE and the Canopus Foundation will put the focus of the second »Solar for All« contest on solar village and mini-grid solutions and their highly recognized potential for rural development. Further information on submission criteria will be released late 2015.

Storage and heat transformation technologies – important pillars of the energy transformation – Fraunhofer ISE expands range of research and development with new site
Jul 06, 2015

Since being founded more than 30 years ago, the Fraunhofer Institute for Solar Energy Systems ISE has covered a wide range of complementary technologies, optimally preparing it for the challenges facing the energy transformation. In addition to solar technology research, the systemic aspects and questions regarding energy storage also played a role right from the start. Today energy storage technologies and efficient heating and cooling processes are two topics particularly in the focus of the energy transformation. Fraunhofer ISE has now consolidated its activities in these areas at its new site on the Auerstrasse in Freiburg. The new location offers much more space which has allowed the Institute to significantly expand its laboratory equipment. On July 2, 2015, the new center for storage and heat conversion technologies was officially inaugurated in the presence of representatives from several German federal ministries as well as from industry associations and the industry itself.
