EFFECT OF LIGHT ON THE RESISTANCE OF Bi/Pb SUPERCONDUCTORS SYNTHESIZED BY SOLAR ENERGY

The aim of the work is to expand the capabilities of solar technologies and areas of practical use of superconductors. The effect of white light on the interaction of superconducting ceramics with a magnet at room temperature was investigated. It has been established that the magnet is “ejected” by ceramic samples of nominal Bi1,7Pb0,3Sr2Ca(n-1)CunOy, (n = 5-20) under the influence of white light and there is no effect in the dark. The resistance of Bi/Pb superconducting ceramics is reduced by exposure to light compared to resistance in the dark. The resistance of ceramics containing higher superconducting higher superconducting phases Tc = 267-295 K is lower in comparison with “nitrogen” ceramics Tc = 110-120
