Optimize Light Absorption and Light Scattering

  • Use Setfos Absorption to model light absorption in thin-film photovoltaics. The interference pattern can be calculated to optimize all layer thicknesses and achieving maximum absorption in the device active layer.

  • Use Setfos Advanced Optics to optimize light propagation in a solar cell functionalized with scattering elements.

Simulate Charge Transport in Solar Cells

Use Setfos Drift-Diffusion to simulate the current-voltage (IV) characteristics, transient signals and results obtained by impedance spectroscopy.

The simulation results help to understand the device physics and, thereby, improve the efficiency of organic, perovskite and other thin film solar cells.

Simulate PV Upscaling and Solar Cell Arrays

Record efficiencies are normally achieved on small area devices of a few square millimeters. Scaling-up solar cells to larger areas is a challenge.

Use Laoss to model large area solar cells and solar cell arrays. It can be used to optimize the metal grid electrode, or to study the monolithic interconnection between solar cells in a photovoltaic array.
