Anti-charged dust device used on surface of optical system or solar cell

Abstract

The invention discloses an anti-charged dust device used on the surface of an optical system or a solar cell, comprising a substrate, as well as a tin indium oxide layer, a titanium dioxide nanoparticle array layer and a fluorine-containing polymer thin film layer, which are sequentially formed on the substrate, and the substrate is glass used on the surface of the optical system or a silicon chip used on the surface of the solar cell. Under continuous ultraviolet radiation, the surface of the device is continuously positively charged, thereby enabling dust adhered on the surface to finally have the same charge with that on the surface of the device regardless of the original charge of the dust, and further enabling dust particles to be separated from the surface under the action of electrostatic repulsion. In addition, a hole generated by the titanium dioxide layer under the ultraviolet radiation has strong oxidizing property, thereby being capable of decomposing organic matters adhered on the surface of an optical device and playing a bactericidal role. The device can achieve good dust prevention and dust removal effects, and effectively prevent light transmittance on the surface of the optical system or the solar cell from being reduced due to hindrance of the dust.

Description

technical field [0001] The invention belongs to the field of dust protection devices, and in particular relates to a device for preventing charged dust on the surface of an optical system or a solar cell. Background technique [0002] With the rapid development of science and technology, optical systems have been widely used. For optical systems, the hazards of dust cannot be ignored. Dust particles will be charged under the action of the external environment, and under the action of electrostatic force, stick and accumulate on various devices that come into contact with the optical system, resulting in blurred vision, seal failure, reading errors, material wear, mechanism blockage, There are many problems such as a significant decrease in image contrast, a significant reduction in luminous flux, and dust contamination of the camera filter. Therefore, it is necessary to protect the optical system from dust, that is, to take dust prevention and dust removal measures for its...
