Embodiment Construction

[0013] In this embodiment, the division into 6*12 areas is taken as an example for illustration. "6" means that the whole is divided into 6 columns. Column, C column, D column, E column, F column. "12" means that each column has 12 rows, from the beginning to the end, named A1, A2, A3, A4, A5, A6, A7, A8, A9, A10 , A11, A12, B1, B2... until F12. According to the regional position distribution of solar cells, design the corresponding regional position comparison table, and then make the regional position comparison card. During the production process, use an EL tester (a Special equipment for testing the defects of solar cells inside the module) to test the semi-finished / finished solar cells. Through the test, find out the defects of the cells in a certain area, according to the word "positive", record each day's production components in the regional position control card The number of hidden cracks and lobes at the location of the area (that is, write the word "positive" in th...

Abstract

The invention relates to the field of production of a solar cell piece. According to a method for reducing hidden crack and split of the solar cell piece, the solar cell piece is divided into a plurality of regions, a regional position comparison table is built by an excel tool, a regional position comparison card is made according to the regional position comparison table, the hidden crack and split numbers of each regional position of an assembly produced in a day are recorded in the regional position comparison card according to a Chinese word zheng, a data line is introduced to the regional position comparison table built by the excel tool, data of a hidden crack and split comparison card of the regional position of each day is input, a corresponding region of production equipment is checked according to a hidden crack and split concentration region, and a defect of the corresponding region in the production equipment is found out and restored. By the method, the hidden crack and split number of the solar cell piece can be reduced.

Description

technical field [0001] The invention relates to the field of solar cell sheet production. Background technique [0002] At present, solar cells are favored by the market. However, because the voltage of a single cell is too low to provide load capacity, and its physical properties are very fragile, it cannot withstand the damage of the external natural environment. Therefore, it is necessary to encapsulate the cell in glass and other materials to protect it and make it into a photovoltaic module. Can be used for power generation. [0003] In the production of photovoltaic modules, in addition to packaging materials, the core material is cells. However, since the average thickness of the battery sheet is only about 190 μm, equivalent to 1 / 5 of 1 mm, it is extremely thin and fragile. In the production process, hidden cracks and slivers often appear, which increases the work loss rate and reduces the first pass rate. In order to investigate the causes of hidden cracks and l...
