The invention provides a method for preparing a solar cell encapsulation structure. The method comprises the following steps of: 1, preparing a solar cell layer on a transparent substrate layer, turning the back of a back electrode surface of the solar cell layer to the transparent substrate layer, and forming a solar cell component together with the transparent substrate layer; 2, coating a UV adhesive on the back electrode surface of the solar cell layer of the solar cell component, and covering the solar cell layer; 3, smoothing the coated UV adhesive to form a UV adhesive layer; 4, under the vacuum environment, bonding the solar cell component which is coated with the UV adhesive layer with a back panel; and 5, curing the solar cell component and the back panel which are bonded by the UV adhesive layer in curing equipment provided with a ultraviolet lamp through ultraviolet irradiation to convert the UV adhesive layer into a cured UV adhesive layer. In addition, the invention provides the solar cell encap
