• Photocurrents in thin YBa_2Cu_3O_6 films were measured at 300 K and 77 K. It is demonstrated that the classical semiconductor theory holds for this kind of material. The photocurrent results are discussed and compared with luminescence and optical transmission measurements. A large energy shift (0.63 eV), to date not observed in other semiconductors, between the photocurrent and luminescence maxima was measured. An oxygen surplus in the bulk of the sample is assumed to be the reason. Furthermore, it is demonstrated that at the critical temperature (T_c=93 K) of superconductive YBa_2Cu_3O_7 a change in the dark conductance behavior of semiconducting YBa_2Cu_3O_6 takes place.
