The invention belongs to the technical field of A. The invention particularly relates to a P-type monocrystal PERC battery capable of improving the LeTID phenomenon. The P-type monocrystal PERC battery comprises a battery body, the bottom surface of the battery body is fixedly connected with a box body, bearings are fixedly embedded in the front surface and the back surface of the box body, inner rings of the two bearings are jointly and fixedly connected with a rotating rod, the inner wall of the box body is fixedly connected with a partition plate, two electromagnets are fixedly embedded in the upper surface of the partition plate, and a signal converter is fixedly connected to the inner bottom wall of the box body. A first permanent magnet and a second permanent magnet can be matched with an electromagnet to control a first connecting plate and a second connecting plate, and the second connecting plate can ascend through a rotating rod when the first connecting plate descends, so the second connecting plate can drive a second permanent magnet to be in contact with a U-shaped water bag and a battery body, and the battery body is cooled, so the problem that due to the fact that the temperature of the PERC battery body cannot be controlled by the PERC battery, the occurrence of the LeTID phenomenon is more frequent is solved.
Description
technical field [0001] The invention relates to the technical field of photovoltaics, in particular to a P-type single crystal PERC cell capable of the LeTID phenomenon. Background technique [0002] A photovoltaic cell is an electrical device that converts light energy directly into electrical energy through the photovoltaic effect, a physical and chemical phenomenon that is a form of photovoltaic cell defined as its electrical A device in which characteristics such as current, voltage, or resistance vary. Individual solar cell devices can be combined into modules, also known as solar panels. Basically, single-junction silicon solar cells can produce a maximum open circuit voltage of approximately 0.5 to 0.6 volts. [0003] PERC cells are one type of photovoltaic cells, and PERC cells have attracted widespread attention in the industry due to their high conversion efficiency. The core of this technology is to cover the back of the silicon wafer with an aluminum oxide or si...
