Zusammenfassung:	The invention relates to a solar cell, a cell module and a preparation method of the solar cell, the solar cell comprises a substrate, a first passivation layer and a second passivation layer, the substrate is provided with a metal contact area and a non-metal contact area, the first passivation layer is arranged on the metal contact area, and the second passivation layer is arranged on the non-metal contact area. The chemical activity of the first passivation layer is higher than that of the second passivation layer, and the refractive index of the second passivation layer is lower than that of the first passivation layer; according to the solar cell and the preparation method, the first passivation layer is arranged on the metal contact region of the substrate, the second passivation layer is arranged on the non-metal contact region of the substrate, the chemical activity of the first passivation layer is higher than that of the second passivation layer, and the refractive index of the second passivation la
