Ultra-thin transparent silver layers for solar cells
New chemical precursor
"The precursors for the deposition of ultrathin silver layers are extremely sensitive to air and light," explains Nils Boysen. It is true that the precursors can be stabilized with fluorine, phosphorus or oxygen. "However, these elements contaminate the thin film and pollute the equipment used to produce the layers," the researcher continues. As part of his master's thesis, Boysen and colleagues developed an alternative for stabilization.
The scientists designed a chemical silver precursor in which the silver is packaged in an amide and a carbene, thus eliminating the need for stabilization with fluorine, phosphorus or oxygen. They showed that the new precursor can be used to deposit thin silver layers on an electrode. To do this, they used atomic layer deposition. In the process, the precursor is transported to the electrode in gaseous form and deposited there as a silver layer just a few atoms thick. Because the silver film is so thin, it is transparent.
"Since the process works at atmospheric pressure and low temperatures, the general conditions would be favorable for industrial production," says Anjana Devi.
Prospect of high-efficiency solar cells and lights
With a series of tests, the researchers demonstrated that the silver thin films produced with the new process are pure and electrically conductive. "From a process engineering point of view, the successful synthesis of the new precursor opens the door to realize ultrathin silver films," Thomas Riedl sums up. "They hold out the prospect of producing new electrodes for highly efficient solar cells and lights."
"The interdisciplinary collaboration between the Bochum materials scientists and the Wuppertal engineers was the key to success," says Anjana Devi.

Photonik-Akademie at Ruhr-Univesität Bochum and INP Greifswald
From 9 to 14 September, 29 MINT students from Germany and Switzerland were introduced to the application potential of plasma technology. The trip went to the laboratories of the Ruhr University Bochum, the INP Greifswald and the Dortmunder OberflächenCentrum "DOC", to the Fraunhofer IWS project group located there and to Cortronik GmbH in Rostock, an industrial partner.
This year, the joint academy of the Federal Ministry of Education and Research and the photonics industry was hosted by the Chair of General Electrical Engineering and Plasma Technology of the Ruhr University Bochum and the Leibniz Institute for Plasma Research and Technology e. V. in Greifswald.
For the students, the schedule was filled to the brim with information and exciting excursions. "I am very grateful for this eventful week," says Academy participant Ediz Herkert, who is studying photonic engineering in the Master's program at the University of Stuttgart. "On the one hand, we got to know the different areas in which plasma technology is used. On the other hand, we had the opportunity to establish contacts with companies and research institutions. The group of participants has also grown into a community during this week. "

Blue Square of Ruhr-Universität celebrates a jubilee
On Septmeber 15th, 2018, the Blue Square in Bochum celebrates a jubilee. At 11:30 the opening of the event starts with an official presentation of the heads of the Ruhr-Universität Bochum. Afterwards, scientific experiments for children and adults are presented on the different levels of the Blue Square. Furthermore, oral presentations are shown. Especially, Prof. Achim von Keudell holds a preseantion about Plasmas supporting energy storage. This presenation starts at 14:30 on level 3 of the Blue Square.
A short description of the presentation is: Plasmas may play a central role for the energy revolution. The vision of scientists is to build a small plasma system, which can be developed at the foot of a wind turbine producing solar energy, so-called solar fuels. Find out how exactly the could look like.
More information about the celebrating day can be found on the webpage of the Blue Square.

Three PhD student from experimental physics II department join Gordon Research Conference
This years Gordon Research Conference on "Fundamental Insights into Plasma Processing" was held at the Bryant University in Smithfield, Rhode Island from the 5th to the 10th of August. The additional Gordon Research Seminar for PhD students, Post-Docs and young scientists started at the 4th of August. The PhD students Sebastian Dzikowski, Katharina Grosse, and Theresa Urbanietz from experimental physics II, RUB, working in the SFB-1316 participated in both the seminar and the conference with poster presentations. Additionally, Theresa Urbanietz was selected to give a students talk at the Gordon Research Seminar. During the Gordon Research Conference, Professor Uwe Czarnetzki from the experimental physics V department gave a talk about challenges in diagnostics with the title "Plasma Diagnostics: What Can We Know? What Ought We Do? For What May We Hope?".
The atmosphere of this conference was very friendly and the discussions between students, post-docs and professors during the poster sessions were both fruitful and motivating. The students had the opportunity during each lunch to sit and eat with different experts (paper editors, scientists in academia and industry...) to discuss their career in a casual environment. The overall programm of the Gordon Research Seminar and the Gordon Research Conference was perfectly put together and the chances for students to discuss their work with advanced researchers in their field created a very unique atmosphere for which the Gordon Research Conferences are famous.

13th Frontiers in Low-Temperature Plasma Diagnostics & 1st Frontiers in Low-Temperature Plasma
The 13th FLTPD workshop on 12th-15th May 2019 is an European event which brings together scientists working on low-temperature plasmas to present their recent results, focusing on original diagnostic techniques. The workshop will take place in the physics center of the German Physical Society in Bad Honnef and is limited to approximately 100 participants from academic, research and industrial institutions.
The program consists of expert presentations from around 10 invited speakers, topical talks selected by the International Scientific Committee from submitted abstracts, and poster contributions. As a rule, all participants will stay at the conference site and are expected to present a contribution.
It is an important and fruitful opportunity for young plasma scientists to share and discuss the latest developments in plasma diagnostics with the experts in the field.
The Conference is organized by Prof. Uwe Czarnetzki from the RUB and other European partners.
