| In this application example we calculate the field distribution in a silicon nanowires based solar cell. This is one of many advanced options how to construct better solar cells. As the solar cell performance highly depends on the local absorption of light, FDTD can be an useful tool for exploring in which regions of the sample the light gets absorbed. | In this application example we calculate the field distribution in a silicon nanowires based solar cell.

| Two different models were constructed as shown on the right image. They always consist of several materials (TCO that was handled as ITO, amorphous silicon, crystalline silicon that was treated as Si 100 and eventually also a Sn nanoparticle on the top of the NW that was treated as perfect electric conductor). In model "A" a periodic array of structured is created using single NW/aSi/ITO column and periodic boundary conditions. This can be used to evaluate effect of column spacing films thicknesses, length or tilt on resulting structure performance. In model "B" 3x3 differently tilted columns are used as basic building block for periodic array construction. This is useful to estimate effects of random column orientation. In principle this could be expanded up to 7x7 array basic building block, however for even larger building blocks the computation would be too long and memory demanding. | Two different models were constructed as shown on the right image.
