NOVELTY - The utility model relates to the technical field of water heater, especially relates to a solar photovoltaic photo-thermal component and solar water heater. The solar photovoltaic photo-thermal component comprises: a frame; the outer surface of the frame is black; a photovoltaic component set on the inner side of the frame; the photovoltaic component comprises a back plate stacked in turn; a battery sheet group and a front glass plate; the front side surface of the front glass plate is provided with a graphene film layer; an evaporator set in the frame, and located at the back of the photovoltaic component; the outer surface of the evaporator is black. In the solar photovoltaic photo-thermal component, black appearance can increase the absorption of solar direct and surrounding space heat, improve the photo-thermal efficiency, so as to make the cloudy and rainy day and at night also can absorb enough heat; By setting the graphene film layer, it can use high hydrophilicity of graphene film layer, the front glass plate has self-cleaning function, avoiding the surface of the photovoltaic component is dirt shielding, so as to avoid reduction of generated energy.
