Problems solved by technology

At present, the problems of solar cells are, on the one hand, the short service life of solar cells due to the influence of high temperature and corrosion, and on the other hand, mainly because some dust particles will adhere to the surface of outdoor solar panels after a period of use. Affects the amount of incoming sunlight, which in turn affects the utilization rate of solar cells for sunlight, directly affecting the photoelectric conversion efficiency

Embodiment Construction

[0018] Based on the technical problems mentioned in the background technology, the present invention adopts some new improvement methods for the solar panel system that automatically tracks 180°. The solar cell window self-cleaning device of the present invention includes a nano-diamond film and an automatic dust removal device, the nano-diamond film is coated on the surface of solar cell glass, and the dust removal brush is installed on the surface of the nano-diamond film.

[0019] The preparation method of described nano-diamond film comprises the following steps:

[0020] (1) Mix nano-diamonds, butyl acetate, and terpineol in a mass ratio of 1:2:5, heat ultrasonically for 5-6 hours to 130 degrees Celsius and disperse to make nano-diamond slurry.

[0021] (2) The nano-diamond film is prepared on the surface of the solar cell glass by a film-pulling method, wherein the film-pulling speed is 1-2 mm / s.

[0022] (3) Thermally sinter the prepared nano-diamond film. The thermal ...

Abstract

The invention relates to a window surface self-cleaning device of a solar cell panel system. The window surface self-cleaning device is characterized in that (1) a nano diamond thin film is prepared at a solar cell window; (2) the nano diamond thin film has high temperature resistance and corrosivity resistance; (3) the film prepared by diamond grains of nano grade has the self-cleaning function; (4) fixing shafts for fixing a cleaning brush are added at the two sides of the solar cell panel system which can track for 180 degrees at both the longitude and latitude; when the solar cell panel is rotated to a certain angle, the cleaning brush drops downwards automatically when a sliding force of the cleaning brush is larger than a friction force; the cell panel is swept during the automatic falling process so as to remove the soil and dust covering on the window. The cleaning brush and the cleaning characteristics of the diamond thin film ensure that the soil from the wind cannot stay at the solar photovoltaic electroplate window from two aspects, thereby solving the realistic problem that the solar photovoltaic conversion efficiency is reduced as the window is covered by the soil from the wind.

Description

【Technical field】 [0001] The patent of the invention relates to the application of rapid manufacturing and new materials in the field of photovoltaic power generation and new energy, and relates to a self-cleaning device for the window surface of a solar panel system. 【Background technique】 [0002] Nano-diamond film has excellent properties such as high temperature resistance, corrosion resistance, self-cleaning and high light transmission performance. The current problems of solar cells are, on the one hand, the short life of solar cells due to the impact of high temperature and corrosion, and on the other hand, mainly because some dust particles will adhere to the surface of outdoor solar panels after a period of use. It affects the amount of incoming sunlight, which in turn affects the utilization rate of solar cells for sunlight, and directly affects the photoelectric conversion efficiency. [0003] In view of the above problems, it is necessary to provide a solar cell...
