At PVSEC 2011 (Photovoltaic Solar Energy Conference and Exhibition) which is being held from 5 – 8 September in Hamburg, the Fraunhofer Institute for Electron Beam and Plasma Technology FEP will present new, favorable-cost manufacturing processes for PV cells.Thin film solar cells consist of several layers having different functions.
Using its broad technology portfolio the Fraunhofer FEP is able to deposit these layers on large surfaces on an industrial scale.
The objective of the Fraunhofer FEP in Dresden is to apply layers of excellent quality at higher production rates than currently employed production processes in order to ultimately reduce the production costs.Dr. Torsten Kopte, contact person for solar energy at the Fraunhofer FEP, believes thin film technology has enormous potential: "Currently photovoltaic modules cost several hundred euros per square meter. In the future we expect that vacuum-based coating technologies which we use at the Fraunhofer FEP
will allow the production cost of photovoltaic modules to be reduced by at least 90%.”
The scientists at Fraunhofer FEP have already achieved promising results for depositing back contacts. They have successfully deposited molybdenum layers for so-called CIGS thin film cells, having ten times higher productivity than competing technologies. Dr. Jens-Peter Heinß, scientist at the Fraunhofer FEP, believes there is still further potential for improvement: “The high deposition rate of 60 nanometers per second is just an intermediate result and I am sure that we can increase this further. For the time being, it is essential for us that the layer properties and efficiency of the cells remained qualitatively equivalent to those of slower processes.”
At the 26th PVSEC in Hamburg the Fraunhofer FEP will present other back contact layers for CIGS cells and flexible solar cells. For further information please visit us at the joint booth of Wirtschaftsförderung Sachsen (Saxony Economic Development Corporation ) B6-B35.Scientific contact:

Russian researchers together with their French colleagues discovered that a genuine feature of superconductors -- quantum Abrikosov vortices of supercurrent -- can also exist in an ordinary nonsuperconducting metal put into contact with a superconductor. The observation of these vortices provides direct evidence of induced quantum coherence. The pioneering experimental observation was supported by a first-ever numerical model that describes the induced vortices in finer detail.

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.
Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.
Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...
The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.
Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.
