Rotatablely cleaned photovoltaic power generation device

Abstract

The invention discloses a rotatablely cleaned photovoltaic power generation device. The device comprises an installation seat. Multiple solar cell sheets are installed on the installation seat. Each solar cell sheet comprises a silicon sheet printed with back field aluminum slurry. A main rotary shaft and at least one auxiliary rotary shaft are vertically arranged in the installation seat in a penetrating manner. The upper ends of the main rotary shaft and the auxiliary rotation shafts stretch out of the installation seat and are horizontally connected with a cleaning strip brush. The lower ends of the main rotary shaft and the auxiliary rotation shafts are connected with an elevating rotation adjustment assembly. Compared with the prior art, the device is compact in structure; by highly efficiently combining the elevating driving and the rotary driving, all-directional cleaning of the surface of a solar cell plate and storage of cleaning tools can be stably and reliably achieved; complexity of the device is reduced; and a flexible scraping sheet on the cleaning strip brush rotates along with the shaft, so a cleaning process is automatically finished. Thus, cost is reduced; energyconversion efficiency is improved; the serial connection resistance of cells of the solar cell sheets is low; the photoelectric conversion efficiency is high; the surface is flat and smooth; the adhesive force is good; the bending rate is low; and the device has excellent 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...
