Note: An upgraded version of EDNA, called EDNA 2, is now available as an on-line calculator. It is faster, contains more physical models, and allows the user to sweep an input and plot outputs a variety of outputs. Click here to go to EDNA 2.


EDNA (Version 1-2)

EDNA simulates the current within a heavily doped region of a semiconductor in 1D. Its primary purpose is to determine the emitter saturation current J0E and the collection current JLE of an emitter diffusion within a solar cell. These values can also be determined for a back-surface field.
