Abstract
The field of superconductivity has gained much attention in recent years due to the discovery of the high temperature cuprate superconductors. Besides their high transition temperature, they show a variety of physical properties that are remarkably different from those of conventional superconductors, two of these are persistent photoconductivity (PPC) and persistent photoinduced superconductivity (PPS). In this work we present the results of photorresponse in thin films and Josephson junctions of YBaCuO and BiSrCaCuO. This effect produces an enhancement in the conductivity and the critica! current of the films and Josephson junctions after illumination. We argue that this effect is due to photodoping of the oxygen-depleted region in the weak link.
