Ulrike Jahn graduated in physics and leads various research and development projects in the business area of solar energy of the TÜV Rheinland Group in Cologne, Germany. Her work focuses on characterizing PV module technologies and on PV system performance analysis. She is a project manager of an international expert group examining PV system performance and module reliability of the PVPS programme of the International Energy Agency (IEA).
Since 1991 Ulrike works on PV system performance analysis while being responsible for the „1000-roof-programme in Lower Saxony at the Institute for Solar Energy Research Hamelin (ISFH Hameln).
Since 2006 Ulrike focuses on the characterization of PV module technologies and material properties (ZAE Bayern in Erlangen).
Since 2008 she works in the R&D group of solar energy of TÜV Rheinland in Cologne, Germany. Ulrike lead a large research project on the characterization of thin-film PV modules. Currently, her focus is on energy yields and failure conditions of PV modules in different climates.
Since 2010 she is the programme manager of the international energy agency’s PVPS Task 13 and coordinates 60 experts in 20 countries in their common work on performance and reliability of PV systems.
Since 2015 Ulrike collaborates in a European Research Project on Solar Bankability with the aim to evaluate how technical risks will affect the electricity production of PV installations and the expected return on investments.
