The Earth receives the energy in 1 hour required for all human needs in a year. Harvesting solar energy will reduce harmful CO2 emissions and resolve the forthcoming energy deficit that other sources alone cannot make up. The market for stable, cheap, roll-to-roll mass-produced organic solar cells (OSCs) is estimated at 1 billion Euros by 2016. The ITN ESTABLIS will produce a team of 11 ESRs and 4 ERs to harness this pivotal point in Europes development based on a reliable, economically powerful and clean resource. ESTABLIS will be an interdisciplinary and inter-sectorial research and training network. ESRs and ERs that result from ESTABLIS will excel. They will possess a broad skill-set across a range of disciplines that are of absolute necessity to develop the industrial and academic infra-structure in OSCs. Researchers will receive training in the primary areas of synthetic organic chemistry through complementary aspects of polymer science to complete industrial scale photovoltaic device manufacture. To improve the roll-to-roll engineering and stability of opto-electronically active thin-films will require new polymers, surface treatments, rheological appraisals of polymer processing, and ageing studies. A parallel approach will develop the necessary improvements in electronic and opto-electronic properties by clarifying correlations between charge transfer, photochemistry and stability. This project will be run by meticulously interacting groups to increase the stability of strong, flexible, low-cost OSCs to 10 years so that they can be sold on a mass-market basis. ESTABLIS is an exceptionally complementary consortium of field-leading University groups and the worlds chief Industrial companies, namely, the worlds foremost producers of OSCs, Konarka, of conducting polymers, Heraeus, and of semiconducting polymers, Merck. These key European companies are at the heart to ensure that training and technological developments will be industrially operable.

The present Perspective critically re-examines the photophysics of para-distyrylbenzene (DSB) as a prototype of herringbone-arranged H-aggregates to resolve the apparent contradiction of the frequently reported "aggregation-induced emission quenching" in H-aggregates on one side and highly emissive DSB crystals on the other and discusses the signatures and fate of excitons in single- and polycrystalline samples, including size and polarization effects. © 2013 American Chemical Society.

Photoinduced charge transport in 1,1-diphenylethene and 2,3-diphenylbutadiene functionalized with an electron donating dimethylamino group and an electron accepting cyano group is reported. UV-spectroscopy reveals that in these compounds, which incorporate a cross-conjugated spacer, a direct charge transfer transition is possible. It is shown by application of the generalized Mulliken-Hush approach that introduction of an additional branching point in the π-electron spacer (i.e., when going from the 1,1-diphenylethene to the 2,3-diphenylbutadiene) leads to only a moderate reduction (68-92%) of the electronic coupling between the ground and the charge separated state. The σ-electron system is however likely to be dominant in the photoinduced charge separation process. © the Owner Societies 2013. Source

FLEXIBILTIY aims at significantly advancing the competitiveness of Europe in the area of multifunctional, ultra-lightweight, ultra-thin and bendable OLAE systems. The developed OLAE components include disposable and rechargeable batteries, solar cells, DC charging electronics, loudspeakers, audio amplifiers, analogue signal generators, motion and temperature sensors, RF receiver circuits, as well as a touch screen. By combination of these components, a variety of novel multifunctional OLAE systems is enabled. Based on a fully printed sound module, the following complex demonstrators are developed:\n\tTextile integrated audio module including broadcast radio and solar supply\n\tActive receiver tag for wireless streaming of acoustic data and advertising\n\tSecurity tag system with acoustic alarm, motion and/or temperature sensors\nFor the realisation of these systems, the advantages of several flexible OLAE technologies are combined, while keeping cost issues in mind: e.g. a) R2R printing offering ultra-low costs per area for components requiring large areas (e.g. loudspeaker, high-power audio amplifiers and solar cells), 3-D integration, as well as the integration of heterogeneous devices on one single substrate; and b) compact (down to 10 micrometer gate length), super-fast (> 200 MHz transit frequency, mobilities > 10 cm2/Vs), low-loss IGZO thin-film technology to enable wireless communication systems. To make efficient circuit development in standard CAD tools possible, design-kits including scalable models and automated layout templates are developed. Interface and packaging issues are studied for full system integration on a common flexible foil enabling bending radii down to 1 cm. FLEXIBILITY combines the complementary competences of 3 large companies, 4 SMEs, 1 research institute and 3 universities. Involved countries are Austria, Finland, Germany, Italy, Greece and Switzerland.

Nanocomposites are promising for many sectors, as they can make polymers stronger, less water and gas permeable, tune surface properties, add functionalities such as antimicrobial effects. In spite of intensive research activities, significant efforts are still needed to deploy the full potential of nanotechnology in the industry. The main challenge is still obtaining a proper nanostructuring of the nanoparticles, especially when transferring it to industrial scale, further improvements are clearly needed in terms of processing and control. The OptiNanoPro project will develop different approaches for the introduction of nanotechnology into packaging, automotive and photovoltaic materials production lines. In particular, the project will focus on the development and industrial integration of tailored online dispersion and monitoring systems to ensure a constant quality of delivered materials. In terms of improved functionalities, nanotechnology can provide packaging with improved barrier properties as well as repellent properties resulting in easy-to-empty features that will on the one hand reduce wastes at consumer level and, on the other hand, improve their acceptability by recyclers. Likewise, solar panels can be self-cleaning to increase their effectiveness and extend the period between their maintenance and their lifetime by filtering UV light leading to material weathering. In the automotive sector, lightweight parts can be obtained for greater fuel efficiency. To this end, a group of end-user industries from Europe covering the supply and value chain of the 3 target sectors and using a range of converting processes such as coating and lamination, compounding, injection/co-injection and electrospray nanodeposition, supported by selected RTDs and number of technological SMEs, will work together on integrating new nanotechnologies in existing production lines, while also taking into account nanosafety, environmental, productivity and cost-effectiveness issues.
