Simulating self-heating, tunneling and multiple light sources in Setfos
Setfos solves thin film optics and drift-diffusion charge transport in one model. This is what that covers now — heat coupled self-consistently to the electrical solution, three tunneling mechanisms, as many light sources as a bifacial or indoor PV simulation needs, OLED degradation over operating time, and contact-free IMPLS characterization.
Setfos 6.1 is here with multiple light sources and IMPLS
Setfos 6.1 adds multiple light sources, IMPLS simulation, trap-assisted tunneling with the Hurkx model, new optical outputs and seven new tutorial examples for bifacial tandems, TOPCon and GaAs tunnel junctions.
Faster industry R&D with Setfos workflows
Academic case studies with direct industry relevance. See how leading research groups combine Setfos and measurement to uncover loss mechanisms, guide stack design, and build workflows that scale into industrial R&D.
