A kind of solar cell production process

Abstract

The invention belongs to the technical field of solar cell production and particularly relates to a solar cell production process. The production process comprises the following steps: a cell slice isput in a cell tester for test; a bus bar is welded on a main grid line on the front surface (negative electrode) of the cell slice; cells are manually connected in series and welded to a module string; the module string, glass, well-cut EVA, glass fiber and a backplane are laid well according to certain layers and are then put in a lamination machine for lamination; a glass module is loaded to analuminum frame, and a gap is then filled by using silicone resin; the pressure resistance and the insulation strength of the module are tested, the module after the test is put in a pressure tester,and the ability of bearing loads such as wind and snow by the module is tested. A sand sprinkling device is arranged above an inclined test table, the sand sprinkling device sprinkles sand to the inclined test table, real rain and snow weather is simulated, and high accuracy is achieved for detection on the pressure resistance strength of a cell module.

Description

technical field [0001] The invention belongs to the technical field of solar cell production, in particular to a solar cell production process. Background technique [0002] Solar modules (also called solar panels) are the core part of the solar power generation system, and also the most valuable part of the solar power generation system. Its function is to convert the solar energy into electrical energy, or store it in the storage battery or push the load to work. Solar modules must bear the pressure of strong winds and the gravity of ice and snow during long-term outdoor use. Since the solar modules are mostly installed at an inclination outdoors to receive sunlight to the greatest extent, the frame at the bottom of the solar module is subjected to the greatest force, which is prone to falling out of the frame, resulting in damage to the solar cell module. Therefore, the antistatic pressure strength of the solar module frame is very important. In the process of simulati...

Problems solved by technology

[0004] The pressure test method of this technical solution can simulate the static pressure resistance of the solar module frame, but it cannot truly simulate the pressure of ice and snow gravity on the solar module in the natural state, nor can it simulate the dynamic pressure reflected in the snowing process, and It is difficult to convert the test data into specific values
