Doctoral student receives Erhard Höpfner Thesis Award

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.

    A simpler way to inorganic perovskite solar cells
    Inorganic perovskite solar cells made of CsPbI3 are stable over the long term and achieve good efficiencies. A team led by Prof. Antonio Abate has now analysed surfaces and interfaces of CsPbI3 films, produced under different conditions, at BESSY II. The results show that annealing in ambient air does not have an adverse effect on the optoelectronic properties of the semiconductor film, but actually results in fewer defects. This could further simplify the mass production of inorganic perovskite solar cells.
