The application provides a gradient band gap selenium antimony sulfide solar cell and a preparation method thereof. The gradient band gap selenium antimony sulfide solar cell adopts a double gradient band gap selenium antimony sulfide as an absorption layer. The double gradient band gap selenium antimony sulfide absorption layer is prepared by a jet carrier gas transport vapor deposition technology, with selenium antimony sulfide particles as a source and hydrogen selenide as a selenium source. In the preparation process, the hydrogen selenide flow is adjusted from small to large and then from large to small, so that the double gradient band gap selenium antimony sulfide absorption layer is obtained. The method provided by the application is a method for depositing a selenium antimony sulfide film by using the jet carrier gas transport vapor deposition technology, and the flow of the hydrogen selenide is adjusted, so that the double gradient band gap selenium antimony sulfide absorption layer is prepared. The application provides a new preparation method of the gradient band gap selenium antimony sulfide solar cell, and the band gap structure of the selenium antimony sulfide absorption layer can be effectively optimized, which is helpful to improving the performance of the device.

The application relates to a nanometer ferroselenide assembled microscale material, a preparation method and application. The application discloses a nanometer ferroselenide secondary stacking material, a preparation method and application thereof. The material has a three-dimensional structure, and the three-dimensional porous structure is formed by stacking of ferroferric oxide nanospheres. The preparation method is as follows: iron source containing ferric ions is added into ethylene glycol, and the ferroferric oxide nanometer material with secondary stacking can be obtained through a one-step method.
