We feel that persistent photoconductivity has lacked an adequate microscopic model to date. In an effort to remedy this, we present a cellular automata model based on the idea that trapped electrons in the basal plane lead to structural rearrangements when illuminated with light ranging from IR-UV wavelengths. We interpret our results within a single-band model for the electronic structure of YBCO and find that our results are in good agreement with previous experimental work.
