Innovative solar energy research: efficient technologies for the future
At the Institute for Solar Energy Research in Hamelin (ISFH), we are working on innovative components for the photovoltaic as well as solar thermal utilization of solar energy. The focus is on physical understanding and generalizable technological findings as well as the development of cost-effective processes. The components manufactured at ISFH are tested in energy systems, as only their behavior within a system decides whether a development is successful. The system itself is in this an extremely important part of research work.
We support the utilization of solar energy in collaboration with our partners from industry and our students through research and innovations.
Departments at the ISFH
Photovoltaics
In photovoltaic research, the tasks include fundamental material examination as well as the development of processes and systems for the production of solar cells. The main focus is on the development of new silicon solar cells with efficiencies of more than 24%, highly efficient tandem solar cells and the associated PV module technology. The overriding aim is to reduce the production costs of solar cells and PV modules.
Solar systems
The Solar systems department focuses on the integrated overall energy supply of electricity and heat for decentralized units such as buildings and settlements. The objective is a cost-effective and low-CO₂ energy supply in high-quality systems. To this end, ISFH develops, evaluates and optimizes thermal solar collectors, heat pumps, innovative coating processes, storage concepts and new applications and combinations for energy systems.
CalTeC
The ISFH CalTeC (Calibration and Test Center) offers independent and accredited measurements for the calibration of silicon solar cells and for testing solar absorber coatings, spectroradiometers and solar thermal systems and components.
Central services
The Central services support the entire infrastructure of the institute. They consist of an administrative department, to which the secretariat, accounting, legal and human resources departments are assigned, and the corporate development department, which comprises the technical areas of building services, mechanical workshop and IT as well as public relations.
