Description

Solar cell passivation film plating device and equipment
Technical Field
The invention relates to the technical field of solar cell passivation coating, in particular to a solar cell passivation coating device and equipment.
Background
In recent years, with the rise of new assembly technologies such as half-cut assemblies and laminated assemblies, it is necessary to divide a single battery into two or more pieces when manufacturing the assemblies. The method for dividing the solar cell in industrial application generally comprises the steps of laser scribing, mechanical splitting, thermal laser splitting with low damage and the like. The recombination rate of the surface of the broken section of the cell is high, and the electrical performance of the solar cell can be greatly influenced. For example, after the Topcon solar cell is divided into two by using a laser scribing mode, the conversion efficiency of a half cell is reduced by 0.2-0.3% due to the increase of edge recombination, the open-circuit voltage of the heterojunction solar cell is higher, and the efficiency is reduced more after laser splitting. The reduced efficiency of the solar cell caused by the laser splinter directly results in reduced power of the assembly.
The passivation film coating is to form a layer of passivation film on the surface of the battery piece in a deposition mode, so that the effects of reducing minority carrier recombination, providing a field passivation effect and reducing reflectivity are achieved. Along with the increasing quality of N-type silicon wafers and the increasing efficiency of batteries, the cutting loss is also increased, and passivation coating of the cut surface of the battery piece after slicing is also more important.
The existing solar cell has the following problems in passivation coating: in order to improve the production efficiency, the battery pieces are stacked and then subjected to section passivation coating. However, the height of the metal grid lines on the front and back sides of the printed battery plates is usually 10-30 μm, and gaps exist between the stacked battery plates due to the existence of the metal grid lines.
