As we all know, resistivity is a key factor affecting the photoelectric conversion efficiency of solar cells, and will directly affect its actual efficiency after being put into production. Photovoltaic enterprise users and their solar cell manufacturers usually use sophisticated solar cell testing equipment to scientifically test them after production is completed to ensure that the resistivity is within the ideal threshold after production and is put into normal use. To this end, Millennial Solar produced TLM Contact Resistance Tester, which is widely favored for its fast, flexible, scientific, accurate and testing efficiency. Photovoltaic enterprise users and their cell manufacturers can use this equipment to efficiently evaluate the contact resistance, line resistance and other resistance efficiencies of solar cells. And it can solve the problem that scientific guarantee cannot be carried out through scientific experiments after the completion of electrode production, diffusion, sintering and other production processes! 

TLM Contact Resistance Tester——Provide you with scientific guarantee

Providing scientific quality assurance is the most important function of testing equipment. However, an excellent solar cell testing equipment often provides a series of excellent functions in addition to quality assurance such as speed, accuracy, and flexibility on the basis of scientific quality assurance. This is different from other traditional solar cell testing equipment.

In solar cell electrode optimization, contact resistance is an important aspect that needs to be considered. The value of the contact resistance is not only related to the contact image, but also to the diffusion process and sintering process. Using the TLM Contact Resistance Tester produced by Millennial Solar to measure contact resistivity can reflect problems in diffusion, electrode production, sintering and other processes. The contact resistivity test and line resistance test provided by this equipment can be switched between.

●The measurement range can reach 0.1~120mΩ*cm＾2;

● Static test repeatability ≤1%, dynamic test repeatability ≤3%

● Line resistance measurement accuracy can reach 5% or 0.1Ω/cm

● Contact resistivity test and line resistance test can be switched at will

● A variety of probe heads can be customized for measurement and analysis

Intelligent vision function - achieve precise positioning

 TLM Contact Resistance Tester's intelligent visual positioning function is based on a high-resolution industrial camera and a vision algorithm control system to achieve intelligent positioning, so that it can quickly focus on the grid lines of solar cells, and realize visual recognition through this function, automatically press down and carry out testing. This function can greatly reduce detection time, thereby greatly simplifying test steps and improving test efficiency.

Multiple test platforms - can be switched at will

 TLM Contact Resistance Tester can freely switch between the contact resistance test platform and the line resistance test platform according to the needs of photovoltaic enterprise users and their solar cell manufacturers. Solar cell manufacturers can make adaptation selections based on the solar cell performance categories they need to measure.

The contact resistance test platform is used to test parameters such as contact resistance, sheet resistance, contact resistivity, etc. It has a total of 22 small compartments, which can accommodate 22 small cut solar cells at the same time, and can measure the 22 cut solar cells. The resistance performance parameters of the cells are compared one by one or uniformly. By measuring many cut solar cells, the inspection time can be greatly reduced, and the inspection results can be presented clearly and objectively in the form of images at a glance. The line resistance test platform can be used to measure the line resistance of solar cells. The test platform can be arbitrarily switched in size according to the cut solar cell size provided by the cell manufacturer. It can also have the ability to arbitrarily switch sizes based on the function of the contact resistance test platform. Unique functions to help solar cell manufacturers conduct accurate detection and efficient production processing!

On the basis of completing the efficient production of solar cells, it is often necessary to ensure efficient production through efficient testing. TLM Contact Resistance Tester can use its unique testing advantages and scientific testing functions to provide efficient and scientific precision testing for solar cells after the diffusion, sintering, electrode production and other production processes are completed, thereby assisting photovoltaic enterprise users and their solar cells. Manufacturers produce high-quality solar cells and put them into practical use!
