Possible mechanisms of the decrease in the critical current density j c with increasing defect concentration have been considered on the basis of calculations of j c in a model system imitating a high-temperature superconducting layer. It is concluded that the main mechanism of the decrease in the critical current is the reduction of the effective pinning potential caused by the increase in the defect concentration.
