Abstract

The invention discloses a rotatable and clean photovoltaic power generation device, which includes a mounting base. A plurality of solar cells are installed on the mounting base. The solar cells include silicon wafers printed with back field aluminum slurry. The mounting base is vertically penetrated. There is a main rotating shaft and at least one auxiliary rotating shaft. The upper ends of the main rotating shaft and the auxiliary rotating shaft extend out of the mounting base and are respectively connected horizontally with cleaning strip brushes. The lower ends of the main rotating shaft and the auxiliary rotating shaft are connected with a lifting and rotating adjustment assembly. Compared with the existing technology, the present invention has a compact structure and efficiently combines the lifting drive and the rotation drive. It can stably and reliably realize all-round cleaning of the surface of the solar panel and the storage of cleaning tools, reduce the complexity of the equipment, and clean the strip brush. The flexible scraper on the machine automatically completes the cleaning process as the shaft rotates, saving costs and improving energy conversion efficiency. The series resistance of the solar cells is low, the photoelectric conversion efficiency is high, the surface is flat and smooth, the adhesion is good, the warpage rate is low, and it has a wide range of applications. application prospects.

Description

technical field [0001] The invention relates to the technical field of solar cells, in particular to a rotatable and clean photovoltaic power generation device. Background technique [0002] With the increasingly prominent problems of resource shortage and environmental pollution, solar energy, as a clean and renewable energy, has attracted more and more attention from the world. Therefore, the application of solar photovoltaic power generation is becoming more and more extensive. The key component of solar photovoltaic power generation technology is solar cells. In recent years, crystalline silicon solar cells have developed rapidly as the main solar photovoltaic power generation unit. Photovoltaic power generation units have developed rapidly. Among them, the electronic aluminum paste for silicon solar cells is the main product in the solar electronic paste, usually also called solar cell anode paste, which is used for the formation of the back surface field of the solar c...
