<p>The present invention is related to a coating film for a solar cell backsheet with ultraviolet blocking and shifting functions. More specifically, the present invention is about a coating film for a solar cell backsheet which is produced by the following steps: synthesizing a symmetrical cyanine compound by a chemical substitution reaction of the parent of benzoic compound as an additive with ultraviolet blocking and shifting functions; and coating a PET film after manufacturing a coating resin including the symmetrical cyanine compound. With the present invention, a user can selectively block ultraviolet rays that may lower the operation of solar cells and displays while partially converting absorbed ultraviolet rays into visible rays that are effective for solar cell operation, thereby protecting solar cell modules from ultraviolet rays that are the main cause of solar cell degradation.</p> |
