At the spring meeting of the Materials Research Society, Jakob Bombsch received an award for his poster on CIGSe absorbers for thin-film photovoltaics. Bombsch is a researcher in the department for Interface Design headed by Prof. Marcus Bär.
In his doctoral thesis, Jakob Bombsch mainly investigates compound semiconductors made of copper, gallium, indium and selenide (CIGSe), which can be used as absorber material in thin-film photovoltaics. Recent increases in efficiency have been achieved by so-called "post-deposition treatments" of the CIGSe layers with alkali fluorides.
On his poster, Jakob Bombsch presented results on the influence of such post-deposition treatments on the chemical and electronic surface structure of CIGSe absorbers. He analyzed how these changes could be related to the observed increase in efficiency. The investigations were performed with photoelectron spectroscopy in the SISSY laboratory at EMIL, at the HiKE terminal station at BESSY II and the BL15XU beamline at SPring-8 in Japan.
The spring meeting of the Materials Research Society took place from April 22 - 26, 2019 in Phoenix, USA.
- A warm welcome: Summer students start at the HZBOn 1 July 2024, 18 summer students from 15 nations started their work at HZB. Until 23 August, they will be supervised in various research teams and take on their own small project. For many students, this is their first contact with research.
- HySPRINT Photovoltaics Lab inauguratedAfter around four years of renovation, photovoltaics research groups moved into their offices in Kekuléstraße on 20 June 2024. With the reopening, the building has also been given a new name that makes the research more visible: it is now called HySPRINT Photovoltaics Lab.
- New joint leadership for BESSY IIAndreas Jankowiak as new Technical Director and Facility Spokesperson Antje Vollmer share management responsibilities.
Prof. Andreas Jankowiak has been appointed Technical Director of BESSY II with a term of office of three years as of 1 June 2024 by resolution of the HZB board of directors. Antje Vollmer will start her second term as BESSY II Facility Spokesperson on 1 July 2024. Together, they form the new management duo to coordinate the scientific and technical development of the BESSY II X-ray source on behalf of the HZB management.
