During the spring meeting 2015 of the European Materials Research Society the Poster contribution of  Dr. Ah Reum Jeong (HZB-Institute for Heterogeneous Material Systems) was selected for an award.  The young scientist has presented results on electronic and structural properties in relation to chemical composition of molybdenum oxide layers, which are widely applied in photovoltaic as well as optoelectronic devices.

Ah Reum Jeong has completed her PhD in physics at Ewha Womans University in Seoul, Korea. She now works as a postdoc in the Hybrid Material Systems & Nano-Analytics team of Dr. Marin Rusu in the Hybrid-PV-Project. „There are still relevant processes in molybdenum oxide which we do not completely understand yet“, she states.

In her research, she modifies MoO3-layers with defects and analyzes its morphology, structure and work functions at different temperatures by Kelvin probe force microscopy in ultra-high vacuum and Raman spectroscopy. Chemical composition of the films was in addition analyzed by x-ray photoelectron spectroscopy measurements under the guidance of Prof. Dr. Marcus Bär.

„At first I wasn’t aware that among the people surrounding my poster one person was a member of the jury“, Ah Reum Jeong says. „He has asked some quite specific questions and we had a very good discussion. I am really happy about this award since it helps to get even more attention for our work in the scientific community.”

„Ah Reum Jeong has convinced the jury with the scientific quality of her work and with a very clear presentation “, Marin Rusu states.  The poster has been presented at the Symposium "Synthesis, processing and characterization of nanoscale multi functional oxide films".

    Stability of perovskite solar cells reaches next milestone
    Perovskite semiconductors promise highly efficient and low-cost solar cells. However, the semi-organic material is very sensitive to temperature differences, which can quickly lead to fatigue damage in normal outdoor use. Adding a dipolar polymer compound to the precursor perovskite solution helps to counteract this. This has now been shown in a study published in the journal Science by an international team led by Antonio Abate, HZB. The solar cells produced in this way achieve efficiencies of well above 24 %, which hardly drop under rapid temperature fluctuations between -60 and +80 Celsius over one hundred cycles. That corresponds to about one year of outdoor use.
