OLEDSOLAR: Innovative manufacturing processes and in-line monitoring techniques for the OLED and thin film and organic photovoltaic industries

Background

Opto-electronic devices are opening exciting new applications every day. With new display options using pliable substrates such as plastic and flexible glass, OLEDs manufacturers are bringing a wide range of new applications in lighting (e.g. energy efficient lighting) and different type of displays. Similarly, with the emergence of thin-film technologies in the solar cells market, new applications ranging from installations on curved surfaces to building integrated PV has become possible. However, to meet the industry requirements for mass production, including low cost, manufacturing volumes and efficiency, many challenges still need to be addressed. These challenges for OPV, OLED and CIGs are scaled-up from laboratory to mass production, selection of efficient manufacturing processes, employing inspection, control and measurement techniques to improve yield, quality and time-to-market.

OLEDSOLAR aims to tackle these challenges by developing innovative manufacturing processes for critical steps in the production of opto-electronic devices including OLEDs, OPVs and CIGs solar cells. The proposed activities include reconfigurable high yield (>10% improvement) processes to be scaled up, tested at pilot lines and implemented in production line for validation. A complete system of inspection, quality control, functional testing and measurements using advance system and sensors will be optimised in the project for efficient manufacturing of opto-electronic parts. Recycling and re-use strategies will be developed allowing resource efficiency and reduction of high value product wastes. Automation and advance processing software will be developed for overall control and monitoring of roll-to-roll (R2R) and sheet-to-sheet (S2S) manufacturing process.

During 36 months, a multidisciplinary team of leading RTOs and industries in this field will dedicate their resources and effort to perform proposed activities in 8 WPs and guarantee the maximum impact of OLEDSOLAR project.

Benefits

For roll-to-roll production of these components, the correlation between all parameters (materials, production, inspection) and the final device performance needs to be determined as early as possible. For instance, the performance of organic solar cells and organic LEDs is highly dependent on the thicknesses of the constituent layer materials composing the device. The lack of accurate information about the thickness of the thin films would prevent the detection of components that not perform well against design specifications. Without real-time thin film thickness measurements, or continuous yield monitoring directly integrated in the production line, the capacity of optimizing the production process becomes very limited and costly.
