  • HETEROJUNCTION SOLAR CELL AND PREPERATION METHOD THEREOF
    Publication number: 20240297262
    Abstract: A heterojunction solar cell and a preparation method therefor. The heterojunction solar cell comprises: a semiconductor substrate layer; and a back composite transparent conductive film located on one side of the semiconductor substrate layer. The back surface composite transparent conductive film comprises: a first back surface transparent conductive film; and a second back transparent conductive film located on the side surface of the first back transparent conductive film facing away from the semiconductor substrate layer. Both the first back transparent conductive film and the second back transparent conductive film are doped with group III heavy atoms, and the concentration of the group III heavy atoms in the second back transparent conductive film is less than that of the group III heavy atoms in the first back transparent conductive film.
