On 11 February 2020, Max Grischek received the Erhard Höpfner Thesis Prize, worth 2000 euros, which is awarded by a jury of the Berlin Scientific Society for outstanding theses. Grischek studied at the Technische Universität Berlin and wrote his master thesis in the young investigator research group "Perovskite Tandem Solar Cells" at HZB.
In his master thesis Grischek dealt with the improvement of charge-selective contact layers in silicon-perovskite tandem solar cells. "The hole-selective contact layer has to be very transparent to increase the amount of light absorbed in the solar cell. Another way I succeeded in increasing the efficiency was surface treatment of the electron-selective contact," explains Grischek. He achieved an open-circuit voltage of 1.84 volts, a new record for n-i-p silicon-perovskite tandem solar cells. The efficiency of the cell was 20.7 percent
The jury of the Erhard Höpfner Thesis Award awarded Grischeks master thesis "Advancing Charge-Selective Contacts in n-i-p Perovskite Solar Cells towards Monolithic Silicon-Perovskite Tandem Architectures" together with two other works. Since June 2019 Max Grischek has been working as a PhD student in the young investigator research group "Perovskite Tandem Solar Cells", which is headed by Prof. Dr. Steve Albrecht. He is a member of the HI-SCORE International Research School.
- Photovoltaic living lab reaches the 100 Megawatt-hour markAbout three years ago, the living laboratory at HZB went into operation. Since then, the photovoltaic facade has been generating electricity from sunlight. On September 27, 2024, it reached the milestone of 100 megawatt-hours.
- Postdocs at HZB: Crucial for research, innovation and diversityAt HZB, 117 postdocs from 29 countries are employed. They play a crucial role in driving the main research activities, fostering creativity and innovation. To honor them, the Postdoc Appreciation Week was first organised in the USA in 2009 and has in the meantime become a regular event in Germany as well in the third week of September every year.
- 13 trainees start their careers at HZBA new phase of life began for 13 young people on 2 September: HZB welcomed five new trainees, six students on dual study programmes and two participants in a Voluntary Year of Science. They all are starting their careers with great anticipation.
