The present disclosure provides a hybrid heterojunction solar cell, a cell component, and a preparation method, the hybrid heterojunction solar cell comprises a semiconductor substrate having a substrate front surface and a substrate back surface opposite to each other, wherein the substrate front surface is close to a light-facing side of the cell and the substrate back surface is close to a backlight side of the cell; at least two composite layers located on one side of the substrate front surface, each composite layer includes a multi-layer structure of a tunneling layer and a doped polysilicon layer sequentially arranged in a direction gradually away from the substrate front surface. The hybrid heterojunction solar cell, cell component and a preparation method provided by this disclosure can achieve a stable passivation effect on the cell surface, reduce light absorption in the non-metallic areas of the cell, and achieve better process control at the same time.
