▎ 摘 要
NOVELTY - Preparation of solar energy panel, involves providing graphene coating on solar energy panel surface layer. The graphene coating liquid is prepared by dispersing graphene oxide in a solvent. USE - Preparation of solar energy panel (claimed). ADVANTAGE - The method is simple, enables quick drying of coating, and eases subsequent treatment. The obtained solar energy panel increases the average photoelectric conversion efficiency by more than 3%.
