What is Setfos used for?

Setfos is used to simulate and optimise thin-film optoelectronic devices, including OLEDs, solar cells, and photodetectors, using modular optics, device-physics, and thermal coupling workflows.

What can I do during the 1-month free trial?

During the 1-month free trial, you can evaluate Setfos for your multilayer stack and device workflow, run example projects, and assess multilayer optics (absorption and emission), drift-diffusion plus exciton dynamics, and self-consistent thermal coupling relevant to your application.

Which devices can I simulate with Setfos?

Setfos supports thin-film optoelectronic device workflows such as OLEDs, solar cells (including organic and perovskite), and photodetectors, and is designed for multilayer thin-film stack simulations.

Is Setfos right for academia and industry?

Setfos is a good fit if you need reproducible, research-grade simulations for publications or decision-ready results for industrial R&D, especially when comparing multilayer stack variants and linking optical, electrical, and thermal behaviour to device performance.

How do I start the free trial?

“ I highly recommend Setfos, which I mostly use for simulating and understanding both time (TPV, TPC) and frequency domain (IMVS, IMPS and IS) measurements on perovskite solar cells. The user interface is easy to use and manipulate in combination with the scripting and sweep features, allowing to set up and simulate complex experiments easily. The engineers and scientists at Fluxim also provide excellent support and have been very helpful with any questions and clarifications asked of them.”

Is Setfos right for your research?

Setfos is ideal if you:

• Work on perovskite or tandem solar cells

• Need JV/EQE fitting from experimental data

• Simulate hysteresis (ionic transport effects)

• Model thermal effects on real operating conditions

• Want validated multilayer optics for tandems

Setfos may not be ideal if you:

Need large-area device design & FEM electro-thermal modeling (OLED panels, PV mini-modules/arrays) — take a look at Laoss
Need 3D ray tracing for complex light-coupling/textures or optical cross-talk in OLED displays — Laoss Optical is built for this.

Simulate with confidence—before your next build or publication

Model reliable, comparable thin-film device behavior with research-grade simulation. Talk to a Setfos simulation expert to see if Setfos fits your research and development workflow.
