Ultra-thin transparent silver films for solar cells
Recently, our research was featured on the RUB-homepage!Excerpt:
A new fabrication process for transparent ultra-thin silver films has been developed by researchers at Ruhr-Universität Bochum and the University of Wuppertal. The material may help build highly efficient solar cells and light-emitting diodes. However, traditional chemical methods have not been able to produce ultra-thin and pure silver films. A team headed by Professor Anjana Devi and Nils Boysen from the Bochum-based research group Inorganic Materials Chemistry, in collaboration with the group of Professor Thomas Riedl from the Chair of Electronic Devices in Wuppertal, published an article on a new synthesis method in the journal “Angewandte Chemie”.
Check out the article here.

Short Term Scientific Mission (STSM) Award for RUB and Aalto University
The two collaborating research groups from the Ruhr University Bochum – (IMC Group, Prof Anjana Devi) and Aalto University, Finland (Department of Chemistry and Materials Science, Prof. Maarit Karppinen) were awarded the best Short Term Scientific Mission (STSM) at the HERALD SUMMIT 2018. Lukas Mai (RUB, IMC) and Zivile Giedraityte (Aalto University) successfully performed a short research stay at the respective collaborating university.The outcome of these studies were considered as a highly productive and constructive international cooperation and resulted in a publication (Link to publication). Lukas Mai presented these results at the HERALD SUMMIT 2018 conference and was awarded with the “Best HERALD Publication prize”.
Congratulations!

Hycoat Workshop in Ghent, Belgium
Four members of our group participated in the Hycoat Workshop on ALD/MLD in Ghent, Belgium.HYCOAT is a “European Training Network for Functional Hybrid Coatings by Molecular Layer Deposition” which focuses on the development of MLD processes for the fabrication of hybrid thin films implemented in future technologies such as life science and medicine.
Parmish Kaur, who is about to start her PhD in the IMC group will work together with other PhD students of this project and conduct research on MLD precursors and process design.
