With the technological and application innovation in the photovoltaic industry, various materials are used more and more widely, which also puts forward higher requirements for the mechanical properties such as peeling force and tensile strength of photovoltaic cells. The testing method to evaluate mechanical properties requires mechanical tests such as tension, compression, and bending. For this purpose, Millennial Solar produced the Solar Cell Comprehensive Tensile Tester. After the sample is placed, it undergoes a fully digital closed-loop control test and passes through the data processing system to obtain clear and objective measurement data.

Solar Cell Comprehensive Tensile Tester meets the installation and testing requirements of current mainstream manufacturers’ solar cells of various specifications and is widely favored. It is specially used for testing the peeling force and tensile strength of silicon wafers, silicon materials, photovoltaic cell modules and other related products in the photovoltaic industry.

Unique horizontal and vertical integrated design, capable of both horizontal 180° peel strength test and vertical cell bending test;

The horizontal test module can use up to 28 sensors at the same time;

The vertical testing module can be used for tensile, compression, bending and other tests of finished photovoltaic cells or materials;

Comply with GB/T16491-2009, GB/T16491-96 and JB/T17797-95 national standards.

Carefully designed test details components

After years of accumulation in industry application practice, Solar Cell Comprehensive Tensile Tester is endowed with various carefully designed details.

The height of the test fixture can be adjusted to suit the testing of photovoltaic cells of different specifications;

Adjust the horizontal angle of the test fixture to obtain a suitable peel test angle for testing, which is closer to the force direction in actual application of the model and the data is more accurate;

Vernier sensor position adjustment makes adjustment more convenient when changing test types;

The specially-made mini test jaws are convenient for clamping, and the small spacing between stations makes it easier to clamp short welding strip samples.

Multi-busbar test

The horizontal test module can be equipped with 28 force sensors. With the independently developed intelligent software, 28 sensors can be used at the same time, and the test data can be transmitted and displayed at the same time.

28 busbars can be tested at the same time at one time, which not only shortens the clamping and testing time, but also saves a lot of labor costs, greatly improves the detection efficiency, and tests the same cell. The single-sided test time is less than 1 minute, which is shorter than the single-sided test. Group testing can increase the speed by at least 10 to 18 times, fully meeting the testing requirements of mainstream 28-grid, 20-grid, 18-grid, 16-grid, 12-grid, and 10-grid solar cells in the existing market.

Unique horizontal and vertical integrated design

In addition to common horizontal testing equipment, Solar Cell Comprehensive Tensile Tester integrates vertical testing requirements. The vertical testing module is equipped with a 50N and 1000N force sensor for static physical property testing. The structure is simple and beautiful in appearance, takes up less space, and is easy to operate.

Vertical test module

The vertical test module consists of two parts: electrical and mechanical. The mechanical part uses the motor of the electrical part as the driving force. It uses the forward and reverse rotation of the motor to reduce the speed to the speed required for the test through the worm gear and reducer, and then drives it through the screw rod. Drive the intermediate connecting plate to move up and down to cooperate with the tension and compression of the clamp. After the sample has been stretched, compressed, torn or damaged in other forms, the tensile force, pressure value, tearing force value or other form of force value can be read directly on the display to help the user accurately position, adjust and optimize the direction. Equipped with a variety of fixtures to meet various mechanical testing needs such as tension, compression, and bending.

As a commonly used testing equipment in the photovoltaic industry, Solar Cell Comprehensive Tensile Tester is an important tool for evaluating the mechanical properties of cells, photovoltaic modules and other materials. Solar Cell Comprehensive Tensile Tester, with its unique horizontal and vertical integrated design, can conduct 28 main grid tests at the same time, 28 sensors can be used and transmitted at the same time, and it can simultaneously perform horizontal 180° peeling strength testing and vertical cell bending test. Provide manufacturers with reliable data and information, improve testing and production efficiency, ensure the quality and performance of photovoltaic modules, and promote the development of the photovoltaic industry.
