A drift-diffusion model for ion migration and charge carrier transport across a planar perovskite solar cell (PSC).
This code can be used to simulate the internal state of a PSC over time. The three core layers of a PSC, namely the electron transport layer, perovskite absorber layer and hole transport layer, are modelled explicitly in one spatial dimension. The model variables are the electric potential, halide ion vacancies (existing only within the perovskite layer), electrons (within the ETL and perovskite layers) and holes (within the perovskite and HTL). A variety of experimental protocols can be simulated, including changes in the applied voltage and/or illumination intensity that occur over timescales on the order of microseconds to minutes. The code also outputs the current density and voltage which can be used to plot the current-voltage characteristics of a PSC, including current-voltage hysteresis due to the movement of halide ion vacancies.
