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.
Stability testing for solar cells, OLEDs and LEDs
Stability testing needs controlled, comparable data across enough devices. Learn how Litos Lite supports parallel JV, MPP tracking and ISOS testing for solar cells, and how Litos supports OLED, LED and solar-cell lifetime and degradation studies.
CS 4.5 is here and June brings new research highlights
Characterization Suite 4.5 is here for Paios, Phelos and Litos. In this June update, we highlight new software workflows, recent Paios and Setfos customer publications, upcoming PV events, and SimOEP 2026 in Winterthur.
Faster industry R&D with Setfos workflows
