![]() ![]() It is not necessary to setup the spectrum of the FDTD source to match the desired power spectrum of your real source. ![]() Simply specify the wavelength range of interest (300-1000nm in this example). Setup your simulation in the normal way with "CW Normalization" selected (default setting). (note: it is easy to modify the code to include more solar spectrum in the UV direction) Step 1: Run your simulation in the normal way, with the standard source settings. This approach is summarized below, and demonstrated in the associated example files. We first simulate using the built-in source spectrum, and obtain the normalized quantities in frequency domain and then in post-processing, users can analyze any specific source spectrum, without running the simulation. It is relatively straightforward to include the effect of an arbitrary source power spectrum during your data analysis and post-processing. iterative simulation from CHARGE results.run the simulation and then analyze the results.add monitors, and the "solar_generation" analysis groups.add simulation region and boundary conditions, as well as meshing.set the physical layout (geometry and materials).The work flow of FDTD simulations can be summarized as below: This is because the performance of solar cells depend not only high optical absorption, but also effective charge transportation and the output electrical power. WorkflowÄesign and characterization of solar cells require both optical simulations using FDTD and electrical simulations using CHARGE. This page provides an overview of the methodology for simulating solar cells, and a number of helpful tips.
