Fraunhofer Institute for Solar Energy Systems ISE
When one thinks of photovoltaic cells, then it is usually in connection with the conversion of solar radiation into electricity, a main research area at Fraunhofer ISE in line with the energy transformation. However, researchers at Fraunhofer ISE are also working on another application for photovoltaic (PV) cells: Power-by-Light systems (also known as Power-over-Fiber) in which optical power transfer is used to supply electricity to electronics. Energy transmission is carried out in the form of light, and the photovoltaic cell is not used as a “solar cell,” but rather to convert the transmitted laser light into electricity.
