SAVE THE DATE: Adlershofer Science Forum on 11.11.2014 with Poster Session
The Adlershof Science Forum is encouraging exchange among scientists in Adlershof.
Please save the date to participate on 11. November 2014 at „Adlershof Science Forum“ (AFF) of Humboldt-Universität zu Berlin and IGAFA. The event is meant to encourage exchange and communication between scientists working at Adlershof.
Registration and the call for posters is open until 30.10.2014 here. The best poster will be rewarded with 500 Euro. We really want young scientists and students to attend the event ! Please encourage them to participate.
Topics in 2014 are:
- Big Data
- hybrid materials
- Interfaces and boundary surfaces
We are planning three Workshops with short talks and two poster sessions. We will serve pancakes at 11.11 as in some parts of Germany, carnival is starting.
You can register and upload your Poster (DIN A0) until 30. October 2014 here
Your abstract is needed until 3. November 2014.
With best regards
Prof. Dr.-Ing. Anke Kaysser-Pyzalla, Speaker of the management board of IGAFA
Prof. Dr. Peter A. Frensch, Vice president research, Humboldt-Universität zu Berlin

- Bright prospects for tin perovskite solar cellsPerovskite solar cells are widely regarded as the next generation photovoltaic technology. However, they are not yet stable enough in the long term for widespread commercial use. One reason for this is migrating ions, which cause degradation of the semiconducting material over time. A team from HZB and the University of Potsdam has now investigated the ion density in four different, widely used perovskite compounds and discovered significant differences. Tin perovskite semiconductors produced with an alternative solvent had a particular low ion density — only one tenth that of lead perovskite semiconductors. This suggests that tin-based perovskites could be used to make solar cells that are not only really environmentally friendly but also very stable.

- Long-term stability for perovskite solar cells: a big step forwardPerovskite solar cells are inexpensive to produce and generate a high amount of electric power per surface area. However, they are not yet stable enough, losing efficiency more rapidly than the silicon market standard. Now, an international team led by Prof. Dr. Antonio Abate has dramatically increased their stability by applying a novel coating to the interface between the surface of the perovskite and the top contact layer. This has even boosted efficiency to almost 27%, which represents the state-of-the-art. After 1,200 hours of continuous operation under standard illumination, no decrease in efficiency was observed. The study involved research teams from China, Italy, Switzerland and Germany and has been published in Nature Photonics.
