ZnO was one of the first metal oxides used in dye-sensitized solar cells (DSCs). It exhibits a unique combination of potentially interesting properties such as high bulk electron mobility and probably the richest variety of nanostructures based on a very wide range of synthesis routes. However, in spite of the huge amount of literature produced in the past few years, the reported efficiencies of ZnO-based solar cells are still far from their TiO 2 counterparts. The origin of this striking difference in performance is analyzed and discussed with the perspective of future applications of ZnO in dye-sensitized solar cells and related devices. In this regard, a change of focus of the current research on ZnO-based DSCs (from morphology to surface control) is suggested. © 2012 American Chemical Society. Source

This R&I action will focus on optimally combining traditional roll-to-roll (R2R) compatible fabrication technologies such as printing with unique R2R sputtering, ALD and heterogeneous integration for flexible, thin, large-area electronics applications. It is seen that the different R2R fabrication methods all have their strengths and weaknesses such that using a cost-performance-optimized combination of them for a single production will enable new levels of applicability for TOLAE devices for mass markets. The goal of the ROLL-OUT project is to create a multi-purpose technology for, thin, large-area, high-performance, smart, and autonomous systems comprising of integrated circuits (based on metal-oxide thin-film transistors), sensors, and electronics. They will be utilized in advancing the packaging, automotive interiors and textile industries beyond their traditional scope. The key features are high-performance circuits and components. To fabricate high-performance circuits, the project intends to use novel, hybrid, moderate-temperature, roll-to-roll processes, namely sputtering, Atomic Layer Deposition (ALD) and screen-printing on thin, flexible, large-area substrates. This will enable enormous value addition to the products of European industries without adding any significant extra cost. ROLL-OUT has 5 research organizations (RO) and 5 industrial partners (IND). The action has 6 work-packages (WPs) of which 3 are led by ROs and 3 by INDs. The technology development WPs are led by ROs and demonstration and exploitation WPs are led by INDs. The action intends to create 3 tangible industrial smart, autonomous system demonstrators that will be validated by the industrial partners in accordance with standard testing protocols. The action seeks EU funding of 3.66M for a period of 36 months. 356,5 person-months will be dedicated to the work. The consortium consists of partners from 7 EU member states with complimentary expertise essential for the action.

The success of electric vehicles in the mass market depends on the development of high-energy batteries at a competitive price. The research efforts of the past decade have continuously improved the energy densities of batteries, yet electric vehicles have only gradually made their way into the market. A combined surge in both consumer demand and industrial push is now on the verge of prompting a significant market uptake. eCAIMAN will develop a more powerful battery by modifying and improving individual components and technologies to result in a significant overall improvement of the cell. Key innovations include a 5V high- voltage spinel, a high- capacity composite anode, and a stable high- voltage electrolyte. Their cumulative effect will improve total cell capacity by at least 20%. eCAIMAN will not develop high risk / high gain components, due to the higher the risk of failure. This will ensure the success of the project and deliver a market- near product, while at the same time achieving the goals of the call. eCAIMAN scale-up is designed with existing European production technologies and inexpensive materials mined in Europe, thereby reducing the final battery price. The battery is developed in collaboration with large European light, medium and heavy duty vehicle manufacturers, allowing eCAIMAN to address a broad scope of real end-user demands. eCAIMAN will develop a truly European high-performance battery ready for implementation in the global market.

Within Trash-2-Cash, growing problems with paper fibre waste from the paper industry and textile fibre waste, originating from a continuously increasing textile consumption, will be solved through design-driven innovation. This will be performed by using the wastes to regenerate fibres that will be included into fashion, interior and other products. The cotton production suffers from non-sustainable environmental and socio-economical issues and the polyester fibre manufacture produces waste that to date has no viable deposition. Designers will lead the recycling initiative, defining the material properties, and will feed the material scientists to evaluate newly developed eco-efficient cotton fibre regeneration and polyester recycling techniques. The future exploitation will be ascertained through a two-sided exchange between the designers and the end-product manufacturers, also taking into account the consumer-related product needs, and prototypes will be produced in a realistic test production environment. The objectives are to: Integrate design, business and technology to a coherent discipline to establish new creative industries Develop new material and product opportunities via creative design from waste or process by-product Reduce the utilization of virgin materials; improve material efficiency; decrease landfill volumes and energy consumption Use design for recycling with the vision of closing the material loop Create new business opportunities by adding the return loop of the discarded goods to be reused into attractive products Promote development of the creative sector by providing technological solutions for exploitation of waste streams Europes creative industry will be strengthened through Trash-2-Cash taking the lead worldwide in the design for recycled materials area. Moreover, Trash-2-Cash will support a better waste utilization and contribute to reduction of landfill area needs.
