The invention relates to the technical field of solar cells, and discloses a back contact solar cell, a preparation method thereof and a cell module. The back contact solar cell comprises a substrate layer, a first polarity structure, a second polarity structure and an isolation groove, wherein the substrate layer comprises a light receiving surface and a backlight surface which are oppositely arranged; the first polar structure and the second polar structure are alternately formed on one side of the backlight surface of the substrate layer; the isolation groove is formed between the first polar structure and the second polar structure and extends into the substrate layer; a chamfer structure is formed at the end part, close to the first polar structure and / or the second polar structure, of the bottom of the isolation groove, and the chamfer structure is concavely formed from the bottom surface of the isolation groove to one side of the light receiving surface. Compared with the isolation groove, the chamfer structure is deeper, conduction between diffusion atoms with different polarities is effectively blocked, the width of the bottom of the isolation groove can be further reduced, meanwhile, effective internal reflection of incident solar rays by one side of the back face is enhanced, and the optical performance of the cell is improved.
