An attempt has been made to explain the experimental observations regarding variation of critical current density with the film thickness between 3 and 65 mum in electrophoretically deposited YBa2Cu3O7-x films on silver (Ag) substrates. It is not possible to explain the phenomenon using the commonly believed concept of self-field degradation of critical current density of weak links between the grains. On the other hand, an increased grain-boundary resistance due to a lesser degree of silver penetration from the substrate with increasing film thickness is proposed to be the cause of the observed degradation of critical current density. The experimental data agree quite well with those theoretically calculated.
