摘要
The present invention discloses a preparation method of a heterojunction solar cell and the heterojunction solar cell. The method comprises: providing a substrate; respectively depositing intrinsic layers at two sides of the substrate; respectively depositing n-type doped layers and p-type doped layers on the intrinsic layers at two sides of the substrate, wherein at least two n-type doped layers and/or p-type doped layers are provided, and the doping concentration of each layer of the n-type doped layers and/or the p-type doped layers is gradually increased in a longitudinal direction away from the substrate; and respectively and sequentially forming transparent conductive oxide layers and electrode layers on the n-type doped layers and the p-type doped layers. Therefore, the conversion and production efficiencies of the cell are increased.
