DrIFtFUSION

An open source drift diffusion code based in MATLAB for simulating solar cells

Dr. Philip Calado <[email protected]>, Dept. of Physics, Imperial College London

DrIFtFUSION is a versatile p-i-n solar cell simulation package. The code uses MATLAB’s built-in Partial Differential Equation solver for Parabolic and Elliptic equations (PDEPE) to solve the continuity and Poisson’s equations for electron density n, hole density p, a positively charged mobile ionic charge density a, and the electrostatic potential V as a function of position x and time t. While the methodology used by the solver for discretising the equations goes beyond the scope of this work, full details can found in Skeel and Berlizns 1990.
