Method for reducing efficiency attenuation of PERC double-sided battery

Abstract

The invention relates to the technical field of battery efficiency attenuation, and concretely relates to a method for reducing efficiency attenuation of a PERC double-sided battery. The method comprises the steps of data collection, real-time wind power data collection and PERC double-sided battery position adjustment, and wind load data collection is that after the PERC double-sided battery is subjected to continuous wind load, a data processing module is used for recording wind load data; the the assembly power attenuation amount of a battery subjected to continuous wind load detection is detected according to the efficiency attenuation data of the PERC double-sided battery, and the assembly power attenuation amount is recorded through the data processing module. The method aims to change the orientation of the battery through detection, comparison and analysis when the wind load is enough to damage the battery so as to prevent a battery crystal from being damaged and the battery efficiency from being attenuated, and the service life of the PERC double-sided battery is prolonged.

Description

technical field [0001] The present invention relates to the technical field of battery efficiency attenuation, in particular to a method for reducing efficiency attenuation of PERC bifacial cells. Background technique [0002] PERC double-sided battery is a kind of solar power generation battery. Through the existing technology, the back side can also generate electricity through solar energy, and obtain higher charging and power generation efficiency than ordinary single-sided batteries. It adopts the same single crystal structure as traditional batteries. When subjected to mechanical load, some crystals will be damaged, which will affect the efficiency of the battery and cause attenuation. In addition to being used in photovoltaic power stations, the battery will be used on traffic lights in areas without circuit laying, usually located on plateau roads.

[0002] PERC double-sided battery is a kind of solar power generation battery. Through the existing technology, the back side can also generate electricity through solar energy, and obtain higher charging and power generation efficiency than ordinary single-sided batteries. It adopts the same single crystal structure as traditional batteries. When subjected to mechanical load, some crystals will be damaged, which will affect the efficiency of the battery and cause attenuation. In addition to being used in photovoltaic power stations, the battery will be used on traffic lights in areas without circuit laying, usually located on plateau roads. Some dangerous street lamps are used to warn vehicles. The high-altitude area will be accompanied by a large wind load when there is sufficient light. When the wind load is large enough to impact the PERC double-sided battery, the single crystal will be broken and the efficiency of the PERC double-sided battery will be attenuated. These locations belong to sparsely populated areas, and maintenance is extremely difficult, so it is necessary to increase the service life of the monomer. The purpose of the present invention is to change the orientation of the battery when the wind load is sufficient to damage the battery through detection, comparison and analysis, so as to prevent damage to the battery crystal. Decrease in battery efficiency, thereby improving the service life of PERC bifacial batteries
