OET brings to market fully printed Organic Photovoltaic –OPV and Organic light-emitting diode- OLED innovative products on flexible substrates that can be installed vertically and on complex and curved surfaces, where conventional solar and lighting products are tricky to install. The business opportunity that OET addresses is the supply of easy to install, flexible customized OPVs and OLEDs in complex shapes and designs with a range color pallet, onto every surface with high conformability, low weight <0,5Kg/m2 and at low cost since the innovative products manufactured by fully Roll-to-Roll printing processes over large area.

In this work, we report the recent advances on the large area fabrication of flexible and lightweight OPVs, where OET R&D team reached a record in power conversion efficiency to 7.4% for a fully Roll-to-Roll (R2R) printed polymer-based single junction Organic Photovoltaic (OPV) cell. The Nanotechnology Lab LTFN of Aristotle University of Thessaloniki independently certified the measured efficiency at simulated AM 1.5 illumination under 1000W/m². The new record 7.4% has successfully achieved for bulk heterojunction polymer: fullerene solar cells in an inverted single device stack, fully printed on a flexible substrate by R2R printing techniques based on slot die coating and inkjet printing for the various layers and electrodes involved.

Based on the support of the running H2020 projects SmartLine1 and CORNET2 for a robust and digital nano-manufacturing of flexible large area OPVs with tailored performance and high production yield, OET will widespread the commercialization of OPVs in existing and new consumer market segments like BIPVs, Automotive, Packaging, Wearables, ICT, IoT, etc, in order to open the way for the Smart Society 5.0.

Physicist, MSc in Nanotechnology, CEO of OET.

Vasileios Matskos has over 25 years’ experience in industries and projects. From 2002 up 2013 he participated as a Business Consultant in the implementation of several Greek investment projects. In 2013 he joined OET with the position of CEO and he coordinated one NSRF project and participated in 2 Horizon2020, 2 FP7 and 2 NSRF R&D projects. Also, he worked in the industry of plastics for more than 10 years. Especially he worked from 1994 in FEROR PLASTICS S.A. in various departments: a) Design and Installation of company’s Quality Management System, b) Certification of the above system according  ISO 9002:1994 in 1995, ISO 9001:1994 in 1999 και ISO 9001:2000 in 2001, c) Set-up and realization of seminars both for the industrial and managerial personnel, d) Installation of software for the computerization  of production line  in corporation with a software company within RETEX project (project manager), e) Project manager in RETEX2, developmental act for company’s diversification, ΜΜΕ project etc., f) Development of company’s new products from the production line (design, supply and installation of mechanical and electronical equipment) until the promotion to the customers, g) Participant and visitor in trade fairs both in Greece and abroad, h) Sales in European Union’s customers and i) Quality Department Manager.

Company Profile:

OET brings solar and lighting innovation products on plastics by providing flexible OPV panels and OLEDs manufactured by fully Roll-to-Roll printing processes into Pilot and Production Printing lines combined by in-line pulse laser scribing technology, robust in-line optical metrology and in-line ink-jet printing system level-architectures. Since the process scaling of Printed Organic Electronics induce many challenges on product delivery, OET has a holistic approach to move up the manufacturing maturity curve to Industry4.0. In this work, we described the latest innovations on the development of a robust feedback and control Platform to connect the in-line metrology tools with the R2R processes to achieve automatic control of the manufacturing process and predictive/preventive corrections to the R2R manufacturing of OPVs and OLEDs.
