▎ 摘　　要

NOVELTY - Reflective coating composition comprises 50-70 pts. wt. resin base material, 10-20 pts. wt. dispersant, 10-20 pts. wt. leveling agent, 5-10 pts. wt. thixotropic agent, 2-6 pts. wt. graphene oxide powder, 1-5 pts. wt. phosphor, 1-5 pts. wt. metal powder, and 1-5 pts. wt. reflective powder. USE - Reflective coating composition for enhancing output power of a solar power generation panel. ADVANTAGE - The reflective coating is uniformly coated on the inner side of the solar backplane after the light passes through the solar cell, the light is further reflected to enhance the utilization of sunlight, thus improving the power generation efficiency of the solar power generation panel, and can emit weak fluorescence when the light is dark, which is convenient for installation and identification. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are also included for the following: 1. a reflective coating, which comprises the composition coated on a solar backplane to form the reflective coating; and 2. a method for preparing a reflective coating, which involves: i. preparing graphene oxide slurry and freeze-dry to obtain graphene oxide powder; ii. melting resin base material, adding dispersant, leveling agent, and thixotropic agent in sequence, after reacting for 0.5-2 hours, adding graphene oxide powder while stirring, and adding phosphor powder, stirring, adding metal powder and reflective powder, stirring until the composition is uniform; and iii. applying the composition uniformly on the surface of the solar back sheet (2), and drying at 60-90degrees for 1-5 minutes to form a coating. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of a solar cell device with a reflective coating. Aluminum alloy frame (1.) Solar back sheet (2.) Anticorrosive transparent glass (3.) First transparent ethyl vinyl acetate adhesive layer (4.) Solar power cell (5. )
