Setfos is simulation software from Fluxim AG for optical and electrical modelling of semiconductor devices, such as OLEDs, organic and perovskite solar cells, quantum-dot devices and photodetectors. Four modules simulate light emission, absorption, light scattering and charge transport. Researchers and developers use it to fit experimental data, sweep material parameters and optimise the layer stack of a device. The package has a graphical interface, uses multithreading and, according to the vendor, works with Python. It is installed on Windows or Linux, and for an evaluation Fluxim asks for a machine ID.
Fluxim AG is based in Winterthur, Switzerland. Switzerland is not an EU member but an EFTA country with an EU adequacy decision. Because Setfos runs locally, your simulation data stays on your own systems; no hosting location is stated for the software itself, so ask the vendor how licensing is verified. For customer contacts, Fluxim's privacy policy says it uses services such as Zoho (CRM, USA) and Mailchimp, covered by standard contractual clauses. The website names no owner or parent company.
