Complete Optical Absorption in Periodically Patterned Graphene

A paper originating from a collaboration between N4E partners CSIC, ICFO and University of Southampton suggests doped graphene could be a perfect light absorber.

The authors demonstrate 100% light absorption can take place in a single patterned sheet of doped graphene. The results are relevant for infrared light detectors and sources, and have been highlighted in Physics Focus and Physics World

Switzerland-based global power giant ABB is investing $20 million in the concentrating photovoltaics (CPV) start-up GreenVolts, furthering its interest in solar technology after it bought a share of Fresnel mirror firm Novatec Solar earlier this year.

ABB’s latest investment, though its venture capital wing ABB Technology Ventures, is part of a $35 million round raised by GreenVolts. It comes just six months after the Californian CPV firm completed a $39 million round, according to the company’s most recent filing with the US Securities & Exchange Commission (SEC), and brings total investment in the firm to more than $110 million to date.

German Federal President awards Novaled’s founders team for the Deutscher Zukunftspreis 2011

Novaled AG, a leading company in OLED and organic electronics technology and materials, is pleased to announce that three of Novaled’s founders have been rewarded with the prize “Deutscher Zukunftspreis 2011” for Innovation and Technology by the Federal President Christian Wulff.

The  team of Prof. Karl Leo (Technical University of Dresden and Fraunhofer IPMS  Dresden), Dr. Jan Blochwitz-Nimoth (Novaled AG) and Dr. Martin Pfeiffer (now  Heliatek GmbH) received in Berlin the Deutscher Zukunftspreis – the German  federal president’s prize for Innovations in Science and Technology. This  annual prize honours creative teams of people realizing breakthrough achievements  in science and the subsequent industrial exploitation of these new scientific  results. “I am very glad that this team won the award”, said German Federal  President Wulff. “…the topic of this team is particularly promising  because it really can make happen the energy turnaround (towards green  energy).” 

„We are very happy about this precious award which is an honor and great recognition of the work of the Novaled team and our partners”, says Dr. Blochwitz-Nimoth, Chief Scientific Officer of Novaled. “At the same time the award is motivating us, to make our vision become reality to significantly improve our life in the 21st century with the help of organic electronics.”

The winners team made remarkable developments in the field of Organic Electronics. At the Technical University Dresden they developed unique OLED technologies able to radically reduce the energy consumption of an OLED product. These technologies find their application in new generations of flat panel display, low power lighting and efficient and flexible solar cells. 

Karl, Jan, and Martin are at the origin of a strong Organic Electronics cluster in Saxony; especially with the creation of Novaled AG and Heliatek GmbH (a producer of organic solar cell products).

The spin-off Novaled has meanwhile successfully commercialised its OLED technologies and materials. Both are used for mass production and can be found in products like new generation flat panel displays (e.g. mobile phone displays) and in energy efficient OLED lightings and Organic Solar Cells.

About OLEDs
OLEDs (organic light-emitting diode) are semiconductors made of thin organic material layers of only a few nanometers thickness. They emit light in a diffuse way to form an area light source. In a fast growing display market OLEDs are key part of a revolution: the dream of paper-thin, highly efficient displays with brilliant colors and great flexibility in design. OLEDs represent the future of a vast array of completely new lighting applications. By combining color with shape, organic LEDs will create a new way of decorating and personalizing personal surroundings with light.

Better access for SMEs to silicon photonics technology · ESSenTIAL

ESSenTIAL is a new EU FP7 project that was recently launched with the goal to allow a better industrial access to silicon photonics technology. This will be realized by expanding the services of the ePIXfab-service, taking care to build a more complete technology chain from idea to product.

Since 2006, Europe has invested in facilitating industrial access to silicon photonics. A most notable initiative is ePIXfab, a collaboration between imec and CEA-LETI. ePIXfab has provided setup training, design kits, and access to multiproject wafer runs.

ESSenTIAL will expand the services of ePIXfab. The partners involved are IHP GmbH (Germany), VTT (Finland), TNO (Netherlands), Tyndall Institute (Ireland) and CMC (Canada). The project will expand the services that ePIXfab currently offers:

• First evaluation (feasibility) studies will be supported.
• A new cost-sharing fiber attachment and integration service will be set up, so that R&D engineers have more facilities to test their chips.
• The technology accessible with the ePIXfab multiproject wafers will include standardized modulators, thermo-optics and Ge photodiodes.
• There will be agreements with several fabs on wafer test and process benchmarking.
• ePIXfab will organize training for these new activities.

The project runs from October 2011 to September 2014 and has a budget of 1.65 million euro. For more information, go to www.epixfab.eu
