Partnering opportunity

Innovative coating for electric energy generation


An Italian SME has developed a transparent coating, using nano technologies, environmentally friendly based on the energy differential thermal (EDT) effect. Thanks to a multidisciplinary approach this coating is suited for window glasses and permits the production of electric energy from solar light and heat. The SME is looking for companies for research collaboration agreement, license and commercial agreement with technical assistance. Target countries mainly in Europe second extra EU

Partner sought

The SME prefers collaboration with companies able to invest in research activities and partnering in research projects. Moreover, preferred partners are private for the following cooperation types: • license agreement: licensing for the use of the application; • commercial agreement with technical assistance: the partner should provide to the company all information about its application in order to set up the production of a customized product


The Italian SME has developed an innovative coating that is able to produce electric energy from heated surfaces (also from the sun). In detail the nanocoating produces electricity from thermal differential (Seebeck/Peltier) effect and needs two surfaces at two differenti temperatures.The coating is transparent, based on nano-particles, and can be easily applied to: -glass windows and doors: the nanocoating, being a transparent thermal conductor, turns out to be completely safe if applied to these materials, transforming the windows into real electricity generators exploiting the difference between the inner and outer surfaces of the glass ; - photovoltaic modules: the efficiency of commercial photovoltaic panels does not exceed 20% due to overheating problems. With the application on a photovoltaic panel of this coating, the EDT- layer does not affect the conversion of light into electricity, given the transparency of the layer itself, and also manages to cool the panel by increasing its efficiency to 40% and producing electricity using the subtracted heat; -Insulation modules for thermal coats: These modules are used as external or internal covering of buildings and apartments to increase their energy efficiency and reduce heat loss. If the surface of these panels were coated with EDT, the difference in temperature between the inside of the house and the outside could be exploited to produce electricity, in addition, by converting the heat into electricity, it prevents the passage between inside and outside, thus improving thermal insulation; - Customized support for energy recovery at an industrial level: large industries are increasingly interested in energy saving and are increasingly adopting solutions that allow them to use energy at a lower cost. Covering metal panels with EDT-layers, in order to create customizable modular structures capable of capturing heat and converting it into electricity, could lead these companies to self-produce part of the electricity required at a very competitive price. With the creation of the smart window as well as having a system capable of producing energy from the thermal differential (external and internal temperature), inserted in a domotic system it can act as an alarm system, since EDT is a thermal detector. It can also detect anomalous presences of people, for surveillance and security. The The SME is open for collaboration with companies, research centres and universities for partnering in research projects. Moreover, preferred partners are private companies for the following cooperations: • license agreement: licensing for the use of the application; • commercial agreement with technical assistance: the partner should provide to the company all the information about its requirements in order the company to set up a customized product - partening in collaborative research funded projects

Advantages and innovations

The advantages of the EDT-nanotechnology coatings are: - energy saving and energy efficiency - improvement of environmental climate sustainability - rational use of renewable energy sources, - implementation with safety and transport systems, - efficiency improvement in smart agriculture, - smart mobility, smart cities sectors, ships, trains, aerospace systems. All customers falling into these categories can take advantage of EDT technology to increase the added value of their products, make them more efficient and competitive within a global business landscape. The practical energy saving solution, at low cost, does not request for aesthetic changes or spaces suitable for installations. As for an exemplum: a coating of about 1800 nanometers is transparent at visible ligth between 380-750 nanometers and with a temperature difference of 10 °C is able to produce 550W/square meter.

How it works

  • Tell us about yourself
  • We’ll discuss with you
  • We put the right partners in touch

EEN help you find the right partner, rather than you going it alone.

Our role is to review and collate the most suitable submissions, and then send them to the client who posted the opportunity. We consult with you, and the client, to make the process professional and easy.

These are live opportunities. Your registration of interest on the site is just like a professional approach to a business at a networking event. To stand the best chance of success, make your submission really sing. Sell why the client who posted the opportunity should work with you. Excite them. Ask questions. Try and avoid copy and pasting words from elsewhere.

Once the client has chosen their partner, we'll introduce them over email and keep in touch with both parties to see how it's going. Sometimes things progress quickly. Sometimes because of changing priorities for either party, things progress slowly, but you never know - your next big business break could start right here.
