Abstract

The invention discloses a fluorocarbon coating layer for a solar cell backplane and a preparation method of the coating layer. The fluorocarbon coating layer for the solar cell backplane is prepared from the following constituents in parts by weight: 30-80 parts of europium trifluoroacetylacetone, 100-200 parts of fluorocarbon resin, 150-200 parts of sodium monofluorophosphate, 40-80 parts of calcium oxide, 80-150 parts of benzyl trimethyl ammonium tribromide, 60 to 100 parts of methyl tetrahydrofurfuryl acrylate, 40- 80 parts of polyisobutylene, 20-50 parts of silicate, 30-70 parts of a stabilizer, and 45 to 55 parts of a surfactant, and prepared by the following steps: uniformly mixing europium trifluoroacetylacetone, fluorocarbon resin, sodium monofluorophosphate, calcium oxide, methyl tetrahydrofurfuryl acrylate, polyisobutylene, silicate, the stabilizer and the surfactant, heating the mixture to 400-600 DEG C, extruding and pelletizing, adding benzyl trimethyl ammonium tribromide, uniformly mixing, and stretching to form film. The fluorocarbon coating layer disclosed by the invention can remarkably lower the coating pressure, so as to reduce the production cost.
