Photovoltaic module and photovoltaic power generation system

Abstract

The invention discloses a photovoltaic module, which comprises a photovoltaic module body, wherein the photovoltaic module body comprises two surfaces, which are a light receiving surface and a back surface respectively; a first barrier layer covers the light receiving surface of the photovoltaic module body; a conductive film layer covers the first barrier layer; a silicon-containing hydrophilic film layer covers the conductive film layer; a titanium dioxide base film layer covers the silicon-containing hydrophilic film layer; the conductive film layer is doped with a titanium dioxide film layer, a tin dioxide film layer or a combination thereof; and the thickness of the titanium dioxide base film layer is smaller than or equal to 9nm. The invention further discloses a photovoltaic power generation system. The surface of the photovoltaic module can generate an antistatic effect through covering of the conductive film layer, so that deposition of dust particles on the surface of the module due to the antistatic effect is reduced. Meanwhile, the conductive film layer can also reflect a certain amount of mid and far infrared light, so that the temperature of the photovoltaic module is prevented from rising too fast; and the generating capacity of the photovoltaic module can be improved.

Problems solved by technology

Although the single-layer anti-reflection film is easy to produce, the bonding force between the single-layer anti-reflection film obtained by this method and the substrate is not strong enough, and it is easy to cause the film layer to fall off when used in harsh natural environments. The anti-reflection performance of the reflective film layer is low, and the control method of its anti-reflection characteristics is single
