The Laoss optics module is a powerful 3D ray-tracer solver used to:

• Simulate in- and out-coupling in OLEDs and solar cells with complex 3D optical elements or surface texturing.
• Model stand-alone 3D optical elements and their contribution to the device.
• Simulate optical cross-talk in OLED displays.
• Coupled Setfos to analyze OLEDs and PVs with complex light-coupling geometries.
• Laoss accepts output from Setfos software (Emission, Reflection/Transmission profile

The Laoss electrical module can simulate the characteristics of displays, large-area OLEDs, and perovskite/organic solar cells with PV modules.

• Optimization of the electrode design. Reduction of electrical losses.
• Studying non-ideal effects in OLEDs and solar cells (e.g. electrical shunts)
• Understanding electrical cross-talk in RGD OLED pixel array.
• IV curves, total power dissipation, fill factor, conductivity, electrical potential

The thermal module can be used to simulate the two-way interaction between heat generation and electrical properties of a semiconductor.

• Calculate temperature distribution in OLEDs and solar cells.
• Study the impact of shunts or layer non-uniformities on the distribution of temperature and electrical potential.
• Non-ideal IV characteristics of OLEDs and solar cells due to electrothermal coupling.
• Coupled electro-thermal model to simulate the two-way interaction between heat generation and electrical properties of the semiconductor.
