Information due to Coronavirus situation
Impact on the work at ISFH
Many of our employees are currently working from home. However, they can still be reached as usual by email and, if available, by work mobile phone. At the institute site itself, the work in the laboratories continues as far as possible under observance of the distance rules.
Direct visits should be avoided as far as possible at present. However, if you wish to visit ISFH, all visitors are required to submit a declaration stating that they have not knowingly had any contact with a person who has been tested positive for coronavirus within the last 14 days.
Right now, acting together responsibly is as important as acting together for the success of the energy transition!
Stay healthy!
Welcome to the Institute for Solar Energy Research in Hamelin (ISFH)

Prof. Dr.-Ing. Rolf Brendel
(Scientific Director and CEO)
For these reasons we foster solar energy by doing applied research in the fields of “Photovoltaics” and “Solar Systems”. “Innovation with impact” is our motto since 30 years. We are cooperating with the industry, with other research institutions, and with universities. ISFH is associated with the “Leibniz Universität Hannover”.
We are happy to answer your requests, whether you are from industry and interested in co-operations or in using our scientific services, or whether you are a student interested in one of our advertised academic works or whether you are interested in one of our job openings. Your ideas count!
Welcome to the fascinating world of science and technology for solar energy!
