Battery assembly production method and battery assembly

Abstract

The invention provides a battery module production method and a battery module, and relates to the technical field of solar photovoltaics. The method comprises the following steps of: manufacturing a circular battery sheet by taking a circular silicon wafer as a silicon substrate; cutting the circular battery sheet to obtain a plurality of slices, wherein the slices comprise a first slice and a second slice, the side line of the first slice comprises a straight line side and an arc line side, and the side line of the second slice comprises two straight line sides and two arc line sides, manufacturing a power generation battery assembly based on the multiple second slices; and manufacturing and obtaining the decorative battery assembly based on the plurality of first slices. According to the invention, processing is directly based on the circular silicon wafer, the silicon rod does not need to be cut off, each slice of the circular silicon wafer is used for processing and forming the battery assembly, and no silicon rod is wasted; and the radian of the arc edge of the second slice is small, the manufactured power generation battery assembly is high in conversion efficiency, the radian of the arc edge of the first slice is large, and the decorative battery assembly manufactured by the first slice is good in attractive effect.

Description

technical field [0001] The invention relates to the field of solar photovoltaic technology, in particular to a method for producing a battery component and a battery component. Background technique [0002] In the solar photovoltaic industry, battery modules formed by cell packaging can increase the power of photovoltaic modules per unit area, thereby reducing the cost of solar cells, so they are widely used. [0003] At present, in order to improve conversion efficiency, square silicon wafers are usually used as silicon substrates to produce battery components. [0004] The inventor found in the process of studying the above-mentioned prior art that the above-mentioned prior art scheme has the following disadvantages: since the cross-section of the silicon rod is usually circular, in order to obtain a square silicon wafer, a large number of silicon rods need to be cut off, and the cut-off Silicon rods are usually discarded as waste products or returned to the furnace for r...
