TCAD simulation methodology for 3-D advanced electro-physical and optical analysis

This is first demonstrated using a full 3-D approach, where a global model includes a part of a solar cell with a textured surface. Due to device complexity, many of them cannot be simulated in the full 3-D setup within a reasonable amount of time. Therefore, derived solutions are proposed, which are based on the combined-mode setup coupling the 3-D TCAD model of the solar cell to a “standard” TCAD (2-D or 3-D) model of the active device. We propose a smart coupling between the device and the package that combines the speed and accuracy of mixed-mode simulation assuming additional 3-D effects.
