Abstract

The invention provides a self-cleaning system and a self-cleaning method for a photovoltaic cell. The self-cleaning system for the photovoltaic cell comprises an N-phase power supply, a conversion switch and an N-phase electrode. The N-phase electrode comprises N polygonal electrodes, the polygonal center positions of the electrodes are same and the separation distances between adjacent two electrodes are equal, and the N-phase electrode generates an electric field wave stretching outward from the polygonal center under the circumstance that the N-phase power supply is connected to the N-phaseelectrode through the conversion switch, so that dust or particles attached to the photovoltaic cell can move directionally under the action of the electric field wave to collect dust of the photovoltaic cell. Under the circumstance of electrifying the N-phase electrode, the electrodes can generate heat to evaporate water on the photovoltaic cell to dehumidify the surface of the photovoltaic cell. The self-cleaning system and the self-cleaning method for the photovoltaic cell have the advantages of being small in energy consumption, long in service life of electrodes and good in dust collecting effect.

Description

technical field [0001] The invention relates to the field of photovoltaic cell dust removal, in particular to a photovoltaic cell self-cleaning system and method. Background technique [0002] As a hot new energy source, photovoltaic power generation has the advantages of clean source and no pollution, and has been rapidly applied and developed. In the actual working process of photovoltaic cells, the light transmittance of photovoltaic cells directly affects the photoelectric conversion efficiency, so it needs to be cleaned Dust and moisture on photovoltaic panels to improve photoelectric conversion efficiency. [0003] In the prior art, a high-voltage dust removal module is usually installed on the photovoltaic panel. The high-voltage dust removal module includes a high-voltage switch connected to the two-phase electrodes and the two-phase electrodes. The high-voltage switch is electrically connected to the high-voltage switching module, and the high-voltage switching modu...
