Flexible organic electronics

The strengths of the Fraunhofer FEP Flexible Organic Electronics business unit are technological innovation and innovative product development through use of numerous processes and facilities as well as a dedicated clean room. Various coating technologies are available, such as vacuum vaporization of organic and inorganic materials, atomic layer deposition (ALD) along with printing and laminating processes as well as laser ablation. Many of these processes can be carried out without breaking vacuum, as well as in combination with inert atmospheres. The precursor and deposition technologies are supplemented by powerful measurement and characterization facilities optimized for the electrical and optical analysis of OLEDs, organic solar cells, and photodiodes.

Development work for flexible OLED modules takes place using individual arched substrates as well as on rolls of materials (roll-to-roll processing). Processing of rigid substrates such as glass or metal plate is likewise available.

The business unit offers its clients the development of processes and technologies for efficient and cost-effective fabrication of innovative OLED lighting solutions. Typical jobs involve client-specific layout and fabrication of OLED demonstration samples for investigating new fields of application, stacked-layer development and efficiency increases for OLEDs, as well as evaluation of barrier films and other materials for flexible OLEDs.

Applications

 

Light

Flexibility of lighting is the vision that fires up imagination of designers and architects. Flexible, personalized, ready to install lighting solutions would allow us to change spaces in buildings, cars and other means of transportation.

 

Smart building and
architecture

In architecture the coating of flat glass with energy-efficient layers for low-energy homes or for renovation of historical buildings is growing in importance. Developments at the Fraunhofer FEP on transparent heat-reflection, sun protection, and diffusion barrier layers on flat glas and flexible polymer substrates ...

 

Transport

Today’s cars reflect our individual preferences. A variety of functions can be implemented through thin-films technologies in optics, lighting and interior as well as through novel systems for connected mobility.
 

Solar energy

Solar energy is converted into heat and electrical energy using solar heating systems and photovoltaic systems, respectively. To develop these technologies further, more efficient systems and low cost manufacturing processes are required.
 

Packaging

The packaging sector is under enormous cost pressure: Packaging materials must not be too costly, but are enormously important for the quality and storage life of the end products. The technologies of the Fraunhofer FEP in the area of vacuum coating and surface modification with electrons are ideal for this task due to their high productivity and the excellent surface properties that can be achieved.
 

Medical applications

The growth in the medical technology sector is being accompanied by a great variety of innovations. The development of new products and medical equipment is often based on sophisticated starting materials.

 

Displays and
Wearables

Displays in consumer and professional applications are getting more and more sophisticated. Smart phones, wearables or TVs are equipped with numerous functions to interactively reflect and capture the world.
