the voltage output by the power supply is 1000-1500V, and the frequency is 10-50 Hz.
In the dust removing device, two electrodes of the transparent dust removing electrode are insulated from each other, and the distance between the two electrodes is 0.8-2.0 mm; the width of each electrode of the transparent dust removal electrode is 0.8 mm-2.0 mm
In the above dust removing device, the insulating transparent solid material as the supporting substrate of the transparent dust removing electrode may be glass, transparent plastic, or the like;
the transparent conductive material of the film etched into the interdigital electrode can adopt ITO film, ZAO film and the like, or other transparent and conductive materials. It is understood that the interdigital electrode can be a flexible interdigital electrode made of a flexible conductive material, so that the dust removing device can be applied to a non-planar dust removing surface, or a non-transparent interdigital electrode made of a non-transparent conductive material.
In the transparent dust removal electrode, the transparent self-cleaning insulating film covering the finger insertion electrode is a titanium dioxide and silicon dioxide multilayer film which is an anti-reflection self-cleaning film, the thickness of the self-cleaning multilayer film is controlled to achieve the purpose of extremely large transmission light (namely anti-reflection), the film is used as the outermost surface of the dust removal device, organic pollutants are degraded through catalysis of ultraviolet light in visible light and decomposed into water and carbon dioxide, and the self-cleaning effect can be achieved.
In the dust removing device, the voltage output by the power supply is alternating-current square wave or trapezoidal wave voltage, and the voltage input by the power supply is direct current of 10-36V (for example, the electric energy generated by the solar cell panel is directly supplied to the dust removing device) or alternating current of 220V.
An embodiment of the present invention further provides a dust removal structure, as shown in fig. 3, the structure includes: a transparent dust removal electrode and a substrate;
the transparent dust removal electrode has the same structure as the transparent dust removal electrode in the dust removal device and is of a three-layer structure (see figure 3), the bottom layer of the transparent dust removal electrode is a support substrate made of an insulating transparent solid material, the middle layer of the transparent dust removal electrode is a finger insertion electrode made of a thin film transparent conductive material and etched on the support substrate, the upper layer of the transparent dust removal electrode is a transparent self-cleaning insulating film covering the finger insertion electrode, and two electrodes of the finger insertion electrode can be respectively used for being electrically connected with electrodes of a power supply;

The shape of the finger electrode can be determined according to the shape of the surface needing dust removal. The anti-reflection self-cleaning film is coated on the outermost surface of the dust-removing structure, and organic pollutants are degraded through ultraviolet light catalysis in visible light and are decomposed into water and carbon dioxide. The thickness of the self-cleaning multilayer film is controlled, and the purpose of great transmission light, namely permeability increase is achieved.
Furthermore, a plurality of finger-inserting electrodes can be arranged in the dust removing device or the transparent dust removing electrode with the dust removing type structure, and the plurality of finger-inserting electrodes can be processed in parallel.
