We report on the persistent photoinduced changes of intrinsic (critical temperature) and extrinsic (FC magnetization and width of the hysteresis loop) superconducting parameters of Tl₂Ba₂CaCu₂O₈ thin films. The relaxation back to the original state is very slow, being of the order of days at room temperature. Qualitatively the observed photoinduced changes may be considered as manifestations of two different types of photosensitive pinning centers in the investigated films.
