  • Method for preparing heterojunction solar cell, heterojunction solar cell and application thereof
    Patent number: 12453190
    Abstract: A preparation method of a heterojunction solar cell includes following steps: depositing a first passivation layer on a first surface of a silicon substrate by using a gas source, a base material of the first passivation layer being hydrogenated amorphous silicon; during depositing hydrogenated amorphous silicon of the first passivation layer, allowing the gas source to gradually incorporate carbon dioxide, and controlling a proportion of carbon dioxide in the gas source to gradually increase with increase of a thickness of the first passivation layer which has been deposited.

  • SOLAR CELL AND MANUFACTURING METHOD THEREOF
    Publication number: 20240204118
    Abstract: A solar cell is provided, includes: a substrate, a first passivation layer, an emission layer, a first conductive layer, a second passivation layer, a back surface field layer and a second conductive layer. The first passivation layer, the emission layer and the first conductive layer are sequentially disposed on a surface of one side of the substrate, and the second passivation layer, the back surface field layer and the second conductive layer are sequentially disposed on a surface of another side of the substrate. The first conductive layer includes a first transparent conductive oxide layer, a first conductive metal layer and a second transparent conductive oxide layer which are sequentially stacked.

  • SOLAR CELL, AND TEXTURED SURFACE STRUCTURE AND METHOD FOR PREPARING SAME
    Publication number: 20240079509
    Abstract: A solar cell, a textured surface structure and a method for preparing the same are provided. The textured surface structure is formed on a surface of a silicon wafer, and the surface has a grid line covered area and a light-receiving exposure area. The textured surface structure includes a first textured surface formed on the grid line covered area, and a second textured surface formed on the light-receiving exposure area. The texture size of the first textured surface is larger than the texture size of the second textured surface.
