Textured Cell with FDTD

solarex06.in : Textured Cell with FDTD

Requires: Blaze/Luminous
Minimum Versions: Atlas 5.22.1.R

This example demonstrates the use of finite difference time domain FDTD , for analysis of solar cells. In particular FDTD is useful in analysis of devices where coherence effects are critical (where device dimensions are on the order of the wavelength of light) and that are not one dimensional and therefore do not allow simple transfer matrix analysis.

In this example we create a device with a randomly textured surface. We then illuminate the device using both ray tracing and FDTD analysis. Finally, we compare the resultant illuminated characteristics.

It is most important to note the differences in the two BEAM statements. You should also notice the introduction of the PML statements for defining FDTD boundary conditions.

It is also important to notice that the FDTD analysis introduces an entire new analysis mesh that is usually much geometrically finer than the device analysis mesh. This mesh can be examined in TonyPlot using the TD.FILE parameter of the BEAM statement.
