Okres sprawozdawczy: 2019-03-01 do 2020-11-30
SmartLine addresses the challenges that are faced by Europe’s industrial stakeholders that aim to bring the innovations in Organic and Large Area Electronics (OLAE) to the market, by the cost-effective manufacturing of advanced OLAE-enabled products in the application areas of energy, lighting, displays and surfaces, electronic circuits, all (bio) sensors, wearables, ICT, IoT, etc. OLAE combines organic, polymer, inorganic and hybrid nano-materials in multilayer nano-structures that can be combined by large-scale manufacturing to conformable & lightweight devices with main applications for energy harvesting by sunlight (Organic Photovoltaic -OPVs) and light emission (Organic Light Emission Diodes - OLED for lighting), to name just a few.
However, until now, the faced bottlenecks and challenges to enable fast OLAE-enabled product commercialization include the insufficient control of the properties of materials and devices, inhomogeneities in their thickness, structure over large areas, low process yield, limited reliability and high consumption of resources, batch-to-batch and run-to-run variations in properties and performance, increased waste and high costs. These delay significantly the market acceptance of OLAE-enabled products.
SmartLine addressed successfully the above challenges and provided efficient metrology solutions to industry in order to achieve a strong productivity improvement for the fabrication of flexible OLAE devices (such as OPVs, OLEDs). During its implementation, SmartLine developed sophisticated non-destructive and robust in-line metrology and control solutions for R2R printing and OVPD processes for traceable measurement of properties and quality of highly integrated nano-layers and devices during their fabrication. This will enable real-time control on the process stability, properties homogeneity, material/device quality and performance reliability.
The objectives of the project are the following:
O1: Development of robust non-destructive metrology tools and methodologies (acquisition, modelling, reference), for the monitoring of properties (optical, electrical, etc.), structure (surface patterns), and quality of OLAE nanolayers in complex & highly integrated nano-scale architectures with high precision. These in-line metrology tools include: a) Spectroscopic Ellipsometry (SE), b) Raman Spectroscopy (RS), c) In-line Reflectometry (REF), d) Wavelength Scanning Interferometry (WSI) for surface features, and e) Eddy Current (EC) measurement system.
O2: Integration of in-line metrology tools in specific parts of unique R2R printing and OVPD pilot to production lines to enable closed-loop fabrication of OPV and OLED devices, that will enable better resource efficiency and increased device reproducibility, yield and productivity
O3: Development of robust feedback and control Platform (MCP) to connect the in-line metrology tools with the R2R and OVPD processes to achieve autonomous control of the manufacturing process and predictive/preventive corrections to the R2R printing and OVPD processes
O4: Optimization of manufacturing processes for OPVs and OLEDs and boost of process yield and device quality, in combination to reduced waste and process time. Validation of the reliability and quality of devices by demonstration to automotive applications (exterior, interior).

The SmartLine project proved that in-line metrology is a crucial component for the reliable, cost-effective and high quality manufacturing of complex OE-based materials, devices and products that consist of complicated architectures of sensitive nano-layers to build highly efficient devices. The progress beyond the current state-of-the-art brought by the project can be summarized on the overcoming of all the technical and scientific challenges to develop and integrate sophisticated metrology tools (with the capability to measure and model in an accurate and robust manner) in large scale manufacturing, without affecting the process.
SmartLine has a significant continuous impact in Europe’s manufacturing industry, in the following parts:

- Providing robust solutions to identify defected parts of printing layers that result to defected OPV and OLED devices. In addition, it has allowed the correlation of inhomogeneities in the physical properties across the printed web with malfunctioned or failed devices. These capabilities allow the early removal of the defected parts before the encapsulation and finalization of the OPV panels and OLED devices.
- Optimization of the OLAE manufacturing processes by adjusting key experimental parameters based on the feedback from the in-line metrology tools. This will benefit the manufacturing processes by strongly reducing batch rejections, waste of materials, used resources as well as the trial-cases for new material batches and formulations.
Finally, SmartLine will have a huge impact and will transform the manufacturing processes for Organic Electronics Industry and for other Industries as Thin Films, Electronics, Wearables, Energy, Automotive, Transport, Space, Health, etc., and incorporate them towards the Factory of the Future.
The project results will unleash the huge potential of OPVs and OLEDs in consumer applications and will enable Industrial Growth in Europe. Also, such manufacturing processes will demonstrate a strong productivity improvement in regards to conventional processes that will enable them to remain commercially competitive for multiple application areas.
