Why does sometimes the photo-current in an photo-electrode keep increasing instead of decreasing on illumination?

When an electrode made of semiconductor nanotubes/nanowires etc is illuminated an overshoot or transient maximum in the photocurrent is observed. The photocurrent gradually exponentially decreases...
