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.
