A band-shaped high-temperature superconductor (HTSL) with high critical current density can be produced economically in a wet-chemical process. In the process, a first precursor solution is applied to a carrier, dried, and annealed. Additional precursor solutions may then be applied, with the first precursor solution contain little or no pinning centers, and any subsequent precursor solutions contains a higher concentration of pinning centers than the first precursor solutions.
