Abstract

The invention discloses a transparent backplane for a photovoltaic module and a preparation method thereof. The transparent backplane successively includes, from the outside to the inside, a hydrophobic modified polyvinylidene fluoride film layer, a first fluorocarbon coating layer, a transparent substrate, and a second fluorocarbon coating layer. The preparation method comprises the following steps: coating the two sides of the transparent substrate with the first fluorocarbon coating layer and the second fluorocarbon coating layer respectively to obtain a double-sided coated transparent substrate; coating the outer layer of the first fluorocarbon coating layer of the double-sided coated transparent substrate a hydrophobic modified polyvinylidene fluoride casting film solution which formsthe hydrophobic modified polyvinylidene fluoride film layer on the outer layer of the double-sided coated transparent substrate by a phase inversion method. The transparent backplane has a simple preparation process, is economical and environment-friendly, has good weather resistance, and can be self-cleaned.
