Cds(Cadmium Sulphide) is a photoconductive material (i.e. when light falls on it, it will become a conductor Else it works as a resistor). As we know some metals possess property like superconductivity at their critical Temperature. Does Cadmium sulphide possess the same property (superconductivity) at some critical Temperature. If so then can we switch on or off superconductivity of Cds (at itís critical temperature) by means of switching light on or off falling on it? Another property of superconductor is : it blocks magnetic field surrounding it. If we place photoconductive superconductor in magnetic field & continuously switch on & off light falling on it(by using electronic timer) it will cut magnetic flux (it will block magnetic field when it is superconductor & magnetic field passed through It when it works as a resistor). As per the faradays law electricity will be generated in photoconductive material. If it happens then there will be no loss in converting light energy into electrical energy, as there is no moving part.
