The invention provides a manufacturing method for a magnesium metal rotor magnetic suspension alternating-current motor and belongs to the field of manufacturing of alternating-current motors. A stator used by the magnetic suspension alternating-current motor manufactured by the method is the same as a stator of a traditional alternating-current motor; the basic difference is a rotor of the magnetic suspension alternating-current motor; the rotor of the motor is not made of a silicon steel sheet, and various conductors, such as copper, aluminum or winding wires, are not added; only a magnetism-repelling material, namely magnesium metal, is used for replacing the traditional silicon steel sheet, and is used as the rotor of the motor. The magnesium metal is made into the rotor of the alternating-current motor and the rotor is put into a stator cavity of the traditional alternating-current motor to input alternating current into the stator, so that the stator generates a rotary magnetic field ...

The invention provides a solar battery absorbing layer material and a preparation method thereof, and belongs to the field of solar photoelectric absorption layer materials and semi-conductor materials. In consideration of the rare-earth resource advantage in China, rare earth elements are adopted to replace In to prepare the solar battery absorbing layer material Cu(InxX(1-x))Se2, wherein X is a rare earth element, and particularly, the rare earth element yttrium (Y) is adopted to dope/replace In and Ga to prepare the solar battery absorbing layer material Cu(InxY(1-x))Se2. The consumption of dissipated metals (In and Ga) in the Cu(InxGa(1-x))Se2 solar battery material is reduced, the energy gap of the CuInSe2 series absorbing layer materials is increased, the compatibility of sunlight spectral response is enhanced, and the conversion efficiency of a Cu(InxX(1-x))Se2 solar battery is improved.
