Abstract
The phase composition and superconducting properties of high-temperature superconductors of homologous series of Bi1.7Pb0.3Sr2Ca n − 1Cu n O y (n = 4−9) based on amorphous precursors obtained under the influence of solar energy was studied. The formation of structural defects was established, and their relation with the increase in the temperature of the superconducting transition up to 181 K was assumed.
