While nanotechnology was originally limited to small areas of a few cm2, the quest for lower costs has been the latest years the drive for developing processes utilising larger substrate sizes at increasing throughputs. A typical example is the flat panel display industry where the push to larger gen size and faster processing has resulted in a significant cost reduction. The next challenge here is the move to smaller feature sizes. Large area processing at high speeds is optimal when using roll-to-roll (R2R) processing, able to deliver the ultimate cost reduction. Flexible innovative thin film devices, like organic light emitting diodes (OLEDs) for lighting, photo voltaic (PV) and organic photo voltaic (OPV) modules, organic circuitry, printed electronics and thin film batteries, are currently developed using this kind of processing. The overall objective of Clean4Yield is the development and demonstration of technologies and tools for nano-scale detection, cleaning, prevention and repair of defects and contaminations in nano-scale layers. The R2R production processes for OLED, OPV, and high-end moisture barrier layers on flexible substrates will serve as development platform for the various methods. Clean4Yield will demonstrate that the developed methods increase yield, reduce production costs, and improve performance and operational device lifetimes of these applications. The developed technologies will be easy to adapted for other large-scale production technologies of other nano layer applications.

HIFLEX aims to develop a cost-effective Highly Flexible Printed ITO-free OPV module technology that matches the particular requirements of mobile and remote ICT applications in terms of efficiency under different light conditions, lifetime, cost structure, power to weight ratio and mechanical flexibility. The project intends to accelerate the exploitation of this OPV technology for a wide variety of ICT products in the mobile electronics market. An application-driven research approach will be followed by developing large area, solution processable ITO free OPV using scalable, reproducible and commercially viable printing and coating techniques enabling the low cost production of highly flexible and lightweight OPV products. At the same time it guarantees the technological compatibility with other printed electronic components and systems. The high flexibility and lower costs will be addressed by the solar cell module design we intend to bring into production. The partnership consists of: one SME (Dr Schenk) with invaluable expertise in the inline process and quality control of R2R processed PV, one industry (Agfa) with market tested experience on photographic development of Ag grid lines, PEDOT antistatic coatings and large scale coating as well as developing innovative coating solutions, and five research institutes (ECN, ISE, Ris DTU, Holst centre, MatRI) with a technology focus and with complementary expertise in the field of device and module engineering, up-scaling and large area printing and long-term lifetime testing. We anticipate that this project will result in the demonstration of a new scalable, low cost, solution processable photovoltaic technology and will therefore form the basis of a potentially substantial business opportunity for Europe aiming at developing a new solar cell product with cost and payback characteristics strongly advantaged over existing technologies.

The article provides an overview of the characteristics of modern E-glass inspection systems. Modern inspection and measurement systems can do more than simply detect defects in glass. They help manufacturers of float glass and low-E glass to optimize their production and minimize the amount of rejected glass. Applying several inspection modes instead of only one delivers more detailed defect information. One channel may contain information regarding the absorption effect, another may cover deflection effects and a third may deliver information regarding different reflection intensities. It would be a float glass manufacturers nightmare to have to shut down a line for more than a few hours. Therefore, a very compact solution requiring little space and set up time is essential and allows integration into existing production lines in less than four hours.

Organic photovoltaic modules have been evaluated for their integration in mobile electronic applications such as a laser pointer. An evaluation of roll-to-roll processed indium and silver free polymer solar cells has been carried out from different perspectives: life cycle assessment, cost analysis and layer quality evaluation using inline optical and functional inspection tools. The polymer solar cells were fabricated in credit card sized modules by three routes, and several encapsulation alternatives have been explored, with the aim to provide the simplest but functional protection against moisture and oxygen, which could deteriorate the performance of the cells. The analysis shows that ITO- and silver-free options are clearly advantageous in terms of energy embedded over the traditional modules, and that encapsulation must balance satisfying the protection requirements while having at the same time a low carbon footprint. From the economic perspective there is a huge reduction in the cost of the ITO- and silver-free options, reaching as low as 0.25 € for the OPV module. We used inspection tools such as a roll-to-roll inspection system to evaluate all processing steps during the fabrication and analyse the layers' quality and forecast whether a module will work or not and establish any misalignment of the printed pattern or defects in the layers that can affect the performance of the devices. This has been found to be a good tool to control the process and to increase the yield. This journal is © The Royal Society of Chemistry 2013.
