On Tuesday, 26.03.2019, ISFH welcomed 12 interested young physics students to this year’s “Ein Tag vor Ort – Das Laborbestitigungsprogramm der DPG”. After a short welcome and introduction of ISFH by Prof. Dr. Jan Schmidt, the young students first got an insight into the production of highly efficient Si solar cells, visited the well-equipped laser laboratory and visited the solar cell production technology available at ISFH. After a short lunch break with a snack, they also visited the measuring laboratory for solar cells and test structures as well as the accredited laboratory for the calibration of solar cells. The tour concluded with a tour of the photovoltaic module technology and the laboratory hall for research and development in the field of “Integrated Solar Systems” (ISS).
