Dear Business Partner
It is our top priority to serve you in the best possible way, despite the current turbulences with the Corona virus. I therefore want to give you an update on the status of the Sefar Group, which also includes Monosuisse.
• The Sefar Group complies to all the local regulations with respect to the containment of the Corona virus.
• We have taken additional internal precautions to assure the continuation of our production and the deliveries to you.
• All of our spinning and weaving plants worldwide are currently operating without limitations.
• There is a possibility of national restrictions in countries, where we operate our decentralized fabrication units. This may cause delays in fabricated items. For details, please contact your local Sefar subsidiary.
• Global limitations on freight capacity, in particular for air shipments, may also affect the delivery time.
Being a fully integrated supplier, Sefar controls and ensures the entire supply chain of our technical fabrics, from the yarn production at Monosuisse to the shipping of the fabrics or the finished articles. You are in good hands at Sefar.
Should your operation face any supply challenges where we might be able to help, please let us know. Your contact person is reachable at any time.
We will keep you updated on any changes affecting our delivery performance.
I wish you good health!
Panel lights are becoming larger and flexible. With SEFAR TCS Planar, Sefar has the answer to the need for a highly conductive, transparent electrode; a foil-like substrate containing slightly protruding, fine metallic wires.
This substrate can be coated using common wet or vacuum methods. Due to the high conductivity of the solid metal wires, large area devices with homogeneous lighting can be produced without the need for shunt lines.
Roll to roll processing ability has already been demonstrated by Fraunhofer FEP, and CSEM has proven the concept of printed low-cost, large-area OLEDs. Several other institutes and companies are also working with SEFAR TCS Planar on applications such as Organic Light Emitting Diodes (OLED), Organic Light Emitting Electrochemical Cell (OLEC) and Electroluminescence (EL).
For some years it has been a goal to produce wafer-thin, flexible lamps using OLED technology. An OLED works very efficiently and, unlike an LED, it is not a point-of-light source, but the light is generated evenly over large areas (surface or panel light). SEFAR TCS will allow you to bring OLED lamps to a new dimension.

Flexible and large-area electrochemical cells were prepared on SEFAR TCS Planar by the spray-depositing method under ambient air conditions. Uniform light emission with brightness over 100cd/m² and conversion efficiency of 3.4 cd/A was achieved.

The SEFAR TCF and TCS electrodes developed for EL have a very high conductivity which enables large formats to be produced, lower requirements on the bus bar and a lower energy consumption. Moreover, they have high flexibility and high mechanical resistance (stretchability).
SEFAR TCS Planar is more suitable for the conventional preparation method while SEFAR TCF is destined for production by an inverted method, which is a patented technology by Sefar AG.
