(a) Representation of the experimental JV curve (black dashed lines) and the 99 simulated JV curves (grey) after the 8th step of the GA for LS2 of Cell 3.1. (b) Distributions of V_OC at different stages of the GA. As new sets are generated, electrical parameters evolve towards the experimental value (vertical black line). (c) Example of material parameters distribution for the defects in the perovskite layer. Analysing the material parameter distribution at the end of the GA can offer insights into parameters that may be unknown or not easily measured experimentally.
