Today we officially release Setfos 4.4. Several improvements and new features are introduced in this new version:

New Optical features:

• Mode analysis can now be combined with scattering and multiple incoherent layers

• Light scattering is expanded to cylindrical microlenses and micro-surfaces covered by thin film coatings

• A full BSDF can now be estimated from the scattering transmittance of a single 0° measurement

• Solar cell absorption under diffuse illumination can now be simulated

• Set the Internal Quantum Efficiency (IQE) of solar cell materials

• New material models for optical index determination by ellipsometry, transmittance or reflectance data: Drude model and hybrid material models

New Electrical features:

• Doping can now be modelled as a spatial profile in addition to a constant doping density

• Energy Band diagrams and Fermi levels are now returned as an output

• Simulation of Intensity Modulated Photocurrent Spectroscopy (IMPS)

• Fast Implicit transient calculation is expanded to Runge Kutta both with and without adaptive timesteps
