Abstract
The invention discloses an insulating back plate for a solar photovoltaic cell, which belongs to the technical field of solar photovoltaic cells. The insulating back plate comprises a structure enhancing layer, a first bonding layer, a second bonding layer, a first weather resisting layer and a second weather resisting layer, wherein the first bonding layer is combined to the surface at one side of the structure enhancing layer; the second bonding layer is combined to the surface at the other side of the structure enhancing layer; the first weather resisting layer is combined to the surface at one side of the first bonding layer, which is opposite to the structure enhancing layer; the second weather resisting layer is combined to the surface at the other side of the second bonding layer, which is opposite to the structure enhancing layer; the structure enhancing layer is made of polyethylene terephthalate; the first and second bonding layers are made of polyethylene terephthalate bonding adhesives; and the first weather resisting layer and the second weather resisting layer are made of polyvinylidene fluoride. The insulating back plate has the advantages that the compatibility between the first and second weather resisting layers and the structure enhancing layer is embodied; the electrical insulating performance and the weather resisting performance can be integrally improved; and excellent water vapor penetration resisting performance, the hydrolysis resisting performance and the ultraviolet resisting performance can be embodied, thereby the requirement that the ageing can not be caused when the insulating back plate is used for over 25 years can be met.
