Multiscale modelling and characterization to optimize the manufacturing processes of Organic Electronics materials and devices

Periodic Reporting for period 2 - CORNET (Multiscale modelling and characterization to optimize the manufacturing processes of Organic Electronics materials and devices)

Reporting period: 2019-07-01 to 2021-03-31

CORNET is an ambitious project that is funded under the H2020 Call NMBP-07-2017, that developed a unique EU Open Innovation Environment (OIE) covering the triangle of manufacturing, modelling and experimentation in order to optimize the Organic/Large Area Electronic (OE) materials, materials behaviour and nano-devices (OPVs, PPVs, OLEDs) manufacturing processes by linking the nanostructure features with the macroscopic functionality through multiscale (nano- to macro-) characterization and modelling. This will strongly impact the fast and reliable development of new materials, devices and will enable control of the related production processes (R2R printing and gas transport (OVPD)) to fabricate tailored OE devices and systems to demonstrate to industrial applications (e.g. automotive, greenhouses).
The project objectives are the following:
#1: Develop an effective Open Innovation Environment (OIE) connecting world-class industrial, academic & research experts in Manufacturing, Multiscale Characterization & Modelling, for optimization of OE materials, materials behaviour and process optimization and for reliable database, citable protocols and contribution to standards (TRL4)
#2: Multiscale Characterization & Modelling to Optimize OE materials & devices fabrication and Validation of materials models for faster development cycle and time-to-market. (TRL4)
The project will perform multiscale characterization (optical, electrical, structural) and modelling (DFT, MD, Mesoscopic, Compact, Empirical, Simulation), to optimize the fabrication of OE nanomaterials (organic semiconductors, transparent electrodes, perovskites) and OE devices (OPVs, PPVs, OLEDs).
#3: Optimization of the fabrication of OPV, PPV and OLED Devices by R2R Printing and OVPD Manufacturing Processes in terms of reliability, homogeneity of OE devices properties and performance, and control of OE devices properties. (TRL5)
#4: Efficient large scale Fabrication of tailored (OPV, PPV, OLED) nano-devices by R2R printing and OVPD processes and Demonstration to Industrial applications (TRL6). These are: a) automotive applications by CRF, and b) Mediterranean Greenhouses
During the second Reporting Period (01/07/2019-31/03/2021), the partners have proceed according to the workplan and performed all foreseen activities with minor deviations.

The main research results of CORNET include the following:

- More than 110 participations and 58 Exhibitions in int. scientific conferences, workshops and exhibitions, 123 oral and 17 guest presentations for the publication and promotion of the results of the project
- Publication of more than 80 articles in international media and video presentations for the publication of the actions and results of the project
The project final results proved that the validation of the experimental data from the optical, electrical, and structural characterization of OE nanomaterials by ex-situ and most importantly by in-line metrology methods, with the results from the multiscale modelling, can have a strong benefit for the optimization of the manufacturing processes of complex materials, devices and products that consist of complicated architectures of sensitive nanolayers to build highly efficient OE devices.

The development of the CORNET OIE activities for combined and validated modelling and characterization activities 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.
The CORNET advances on the modelling and characterization of OE nanomaterials and devices are expected to increase the speed of the development of new materials and new device architectures. The CORNET multiscale modelling approach can be applied to other materials systems, providing insights on the performance of the final devices. Also, the characterization tools and methodologies for in-line and real-time metrology (as well as for ex-situ metrology) that are combined through the CORNET OIE, can provide additional information on the properties of the different OE nanomaterials, which can reduce the duplication of work and speed up the development of new materials. The OIE Database and Platform will become centers and hubs of reference for the EU stakeholders specialized in the materials synthesis and process development, which will benefit from established correlations between the structure and final properties of materials.
In addition, the CORNET has connected with other H2020 projects (such as the OIE projects OYSTER and MMAMA) as well as from the EU networks such as EMMC, EMCC, EPPN and EFFRA. This will open the way and ensure that the structure and metadata of the developed characterization and modelling protocols performed in CORNET will be harmonized with other developed solutions, ensuring the acceptance beyond the CORNET consortium.
The developed modelling and characterization protocols can be applied for other nanomaterials, such as inorganic, nanoparticles, copolymers, small molecules, etc. Moreover, the CORNET approaches and protocols, are applicable to devices for applications in Energy, Photonics, Textiles, Construction, Health, Medicine, Space, etc.
