Abstract
The present invention provides a coated steel plate suitable for an inline thin-film photovoltaic module, comprising a steel substrate and a composite insulating layer on the surface of the steel substrate. The composite insulating layer comprises an insulating base layer and a laser scribing buffer layer; one side of the insulating base layer is the steel substrate, and the other side is the laser scribing buffer layer. The laser scribing buffer layer contains at least one of the following components: SiN, where 0.75≤x:y≤1; and Si(R)O, where R is an element selected from Sb, Au, Cu, Sn, and Ag, and 0<x'≤0.05, 1.9≤y′≤2. Since the silicon nitride and the doped silicon dioxide used in the laser scribing buffer layer can exhibit specific colors, part of the energy of the laser can be absorbed during the laser etching process, and the damage and the loss of insulation of the insulating base layer during etching can be avoided, thereby ensuring that the coated steel plate for inline thin-film photovoltaic modules provided by the present invention has stable working performance. Additionally, the present invention further discloses a method for manufacturing the aforementioned coated steel plate.
