Setfos 6.0 – Advanced Modeling and a New Thermal Module
Setfos 6.0 is a major update focused on advanced device physics for OLEDs, perovskite solar cells, and photodetectors. A new thermal module, extended modeling options, and a streamlined interface will help you achieve reliable results faster.
The New Thermal Module
Stand-alone thermal and coupled electro-thermal simulations
Optical heating, Joule heating, Thomson-Peltier heating
Support for steady-state, AC, and transient simulations
Various boundary condition types: Dirichlet, convective, and radiative
Included with the Thermal Module:
New OLED Degradation Model
Simulate typical effects observed during OLED degradation under constant current operation like
Luminance decay

Webinar 16 -Exploring Efficiency and Degradation in Next-Generation OLEDs
For our 16th webinar, we are pleased to welcome our invited guest Prof. Andrew Monkman. Andy is the Director of the University of Durham Photonic Materials Centre and Head of the Organic Electroactive Materials (OEM) Research Group which he founded in 1988. His group's focus is on the photophysics of organic light emitting materials with application in OLEDs and solid-state lighting. Andy will be presenting:
Key Design Rules for Ultra-Efficient Sensitisation in Hyperfluorescence OLEDs
Following on from Andy will be Fluxim's Edoardo Stanzani. Edoardo is nearing the end of his PhD with Fluxim and the University of Valencia and will be presenting the following talk:
Electronic and Excitonic Mechanisms Evolution During OLED Degradation
Date & Time: Tuesday, 11th Nov 2025, 11 am - 12 pm (CET)
This webinar, hosted by Dr. Matthias Diethelm (Fluxim), is a must-attend for researchers from industry and academia interested in OLED research and innovation.
We look forward to seeing you there!
