Multi-source, multi-component spray coating technique for solar cells

Spin coating has been the dominant fabrication method for polymer electronics. However, it is not a high-throughput process and numerous research groups are trying to find a scalable fabrication method for polymer solar cells. One such method, spray coating, is capable of delivering large-area, uniform polymer thin films through a relatively simple process, while offering ample processing possibilities of engineering the film structure. Spray-coating is a high-rate, large-area deposition technique that ensures an ideal coating on a variety of surfaces with different morphologies and topographies. It is frequently used for industrial coating and in-line deposition processes. In spray-coating systems, the ink is atomized at the nozzle by pressure or ultrasound and then directed toward the substrate by a gas. An added advantage of spray-coating is that it is efficient: compared to other techniques only a small amount of the solutions are wasted.

European FP6 nanotechnology research evaluation – little impact, no kidding?

A new 290-page tome titled 'Strategic impact, no revolution' is the result of a year-long effort to study the strategic value and impact of NMP in its wider European and international context, with special focus on the ERA dimension, against the general policy objectives of FP6 and against the specific objectives of NMP. The title of this report refers to the general finding that the third thematic priority in FP6 strategically affected Europe's competitive position and was an important programme which also influenced Member States' policies and research agendas. However, it cannot be directly linked to a revolution with regard to creating substantial scientific or industrial breakthroughs although these were among the explicitly targeted objectives. The program strengthened Europe's position as one of the world leaders in the respective scientific and industrial fields, but did not enable Europe to outperform other key actors such as the United States or Japan.
