When I tried the 3D pillar silicon solar cell example found on (https://kb.lumerical.com/en/index.html?solar_cells_silicon_pillars.html) using a larger pillar spacing and larger solar generation enclosure, the visualizer showed no results and plotting the two-dimensional contour plots of the absorbed power or optical generation profiles gave a complete turquoise plot. May I know how can I get around this problem in the FDTD solver please?
I have also tried using two-dimensional monitors that slice through embedded pillars in the x and y planes to obtain a z-x and z-y cross-sectional color contour plot for the electric field and power but the results are not as expected; the power and electric field contours of the pillars are masked by the power and electric field contours of the embedding material. I have tried non-embedded pillars and the results are as expected but not when the pillars are embedded in a material such as Si3N4 and SiO2. May I know the proper way to do this in the FDTD solver please?
Thank you very much for your attention and I look forward to your advice.
