We are excited to announce our participation in the Glass Forum 2025 in Athens at 31.10 – 01.11, bringing forward our latest Organic Photovoltaic (OPV) innovations for smart, energy-generating glass applications.
Our team will showcase how OET’s transparent OPV technologies integrate seamlessly with glass surfaces — transforming architecture, mobility, and urban environments into sustainable energy sources.
Let’s shape the future of energy-efficient design together! ⚡️
OET proudly participates in TechBlick Berlin (22–23 October), showcasing our R2R Manufacturing innovation in Perovskite Photovoltaics (PPVs). These next-generation solar modules are flexible, semi-transparent, and bifacial, setting new standards for sustainable energy and scalable production.
At the 89th Thessaloniki International Fair, OET proudly presents a true energy revolution: 3rd generation photovoltaics. Flexible and semi-transparent, these innovative solar solutions will soon be mass-produced at the world’s first dedicated factory, located in Thessaloniki (Tagarades).
This breakthrough technology, developed by the Aristotle University of Thessaloniki (LTFN) and OET, has been successfully scaled up globally by OET. Thanks to advanced nano-printing techniques, optical engineering, and the unique properties of these devices, next-generation photovoltaics can be applied almost anywhere: on windows, rooftops, carports and pergolas, greenhouses and open field cultivation, as well as on electric vehicles, wearables, and both indoor and outdoor applications.
These are true bifacial devices, capable of generating power day and night, from any light source, while drastically reducing energy costs and environmental impact.
In agriculture: Functioning as agrivoltaics, they can boost crop yields in greenhouses and open-field cultivation by up to 40%, lower temperatures by as much as 20°C, and protect plants from UV and infrared radiation.
In urban environments: They integrate seamlessly into modern architecture, reducing building temperatures, providing clean energy for both on-grid and off-grid applications, and cutting energy expenses dramatically.
With the advent of mass production, costs will fall significantly, paving the way for large-scale adoption across industries such as automotive, tourism, and construction.
As Em. Margaritis, Chief Investment Manager of OET, emphasizes:
“This is not just innovation; it is one of the rare cases where a Greek company holds a world-first in technology. Starting 35 years ago at Aristotle University of Thessaloniki, OET has now become an international leader.”
From Thessaloniki to the world, Greece sets the example: clean energy, global leadership, and a sustainable path towards a climate-neutral economy.
Organic Electronic Technologies (OET), based in Thessaloniki, Greece, will participate in the Grand Pavois Rochelle (23–28 September 2025, La Rochelle, France), one of the world’s most prestigious boat shows.
With more than 800 international exhibitors and 69,000 visitors at the previous edition, Grand Pavois is a key global event for sailing and boating. OET will showcase the applications of its third-generation organic photovoltaics for sailing boats, offering energy autonomy, lightweight design, flexibility, and semi-transparency, while also filtering harmful UV radiation.
OET coordinates the flagship European project Flex2Energy, which is building the world’s first mass production factory for third-generation photovoltaics, and is a member of the International Nanotech Hub Thessaloniki (NAH).
At this year’s Thessaloniki International Fair (TIF), Organic Electronic Technologies – OET showcased its innovative technologies in the field of green energy. The company is pioneering with flexible, semi-transparent 3rd generation photovoltaics, which combine aesthetics, functionality, and sustainability, contributing to energy savings and the reduction of environmental footprint.
Through the European project Flex2Energy, OET is leading the creation of the first mass-production factory for these photovoltaics, with applications in buildings, greenhouses, and vehicles. The project strengthens technological infrastructures both in urban and rural areas, bringing smarter and more sustainable solutions to our daily lives.
OET’s participation in TIF highlights its commitment to sustainable and innovative development, inviting everyone to discover how technology can create a greener future for all.
Sophia Michailidou, agronomist at OET, discusses the role of AgriVoltaics in combining solar energy with sustainable agriculture during her interview at the International Nanotexnology 2025 Conference, hosted by ΑΠΕ-ΜΠΕ.
OPV installations are transforming buildings, cities, and everyday products into sustainable energy generators. In this video, Prof. Stergios Logothetidis presents real-world OPV applications—from solar pergolas and smart urban furniture to transparent building facades and wearable tech. The presentation includes a tour of the OPV Installation exhibition booth at NANOTEXNOLOGY 2025, as covered by the Athens–Macedonian News Agency.
The International Nanotech Hub, Thessaloniki is a high-tech innovation ecosystem. It serves as a reference point for investment, development, and international collaborations in Nanotechnology and Printed Electronics applications. NHT transforms academic research into commercial products and high-tech services with global impact.
NHT includes, among others, the Center of Excellence COPE-Nano, the companies Organic Electronic Technologies (OET), OPV Installations, BL Nanobiomed and VK NANO.
Organic Electronic Technologies (OET) is leading the creation of the world’s first production plant for 3rd generation photovoltaics. These photovoltaics are semi-transparent, flexible, and lightweight. They can be used in a wide range of applications — for example, in greenhouses — delivering impressive results such as up to 30% increase in production, energy and water savings, and reduced use of cultivable land. They can be integrated into any surface, including building windows, offering unobstructed visibility while blocking harmful UV radiation, creating natural shading, and lowering indoor temperatures during summer.
Beyond its applications and products, the International Nanotech Hub Thessaloniki offers unique opportunities for scientific and business networking by organizing a series of international conferences. The most prominent among them is the International Multi-Conference NANOTEXNOLOGY, which takes place every July in Thessaloniki. It includes multiple conferences, a Summer School, and an Exhibition showcasing high-tech products and applications in Nanotechnology, Organic & Printed Electronics, Nanomedicine, Smart Industry, and more.
NANOTEXNOLOGY is the largest technology, networking and matchmaking annual event in Europe including many premier and Internationally established events.
Visit our booth at NANOTEXNOLOGY EXPO 2025 and experience our new products first-hand!
We will be looking forward to meeting you at our booth to further inform you on all our endeavors and discuss the possibilities of cooperation.
