Production and testing, like productivity and production relations, generally determine or influence each other. In many processes such as diffusion, electrode production, and sintering, solar cell manufacturers usually use solar cell testing equipment with targeted measurement functions to conduct scientific testing in order to evaluate the performance of their solar cells. The TLM Contact Resistance Tester produced by Millennial Solar can accurately detect the contact resistance, sheet resistance, contact resistivity of solar cells and the line resistance of grid lines with its contact resistivity test and line resistance test functions. The measured data is clearly and objectively presented in the interface software that comes with TLM Contact Resistance Tester, thus providing a key role in many production process quality assessments!

TLM Contact Resistance Tester - a new definition of testing equipment

In solar cell electrode optimization, contact resistance is an important aspect that needs to be considered. The size of the contact resistance is not only related to the contact image, but also related 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. And the contact resistivity test and line resistance test provided by this equipment can be switched at will.

● The test range can reach 0.1~120mmΩ*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

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

The test function can be switched to ensure reliable sample positioning

The TLM Contact Resistance Tester produced by Millennial Solar has the contact resistivity test function and the line resistance test function that can be switched at will. Photovoltaic enterprise users can provide targeted scientific testing of solar cell performance according to specific production processes. Analyze the tested data parameters one by one to find out the key reasons for the unqualified solar cell performance from the details.

The contact resistivity test function of TLM Contact Resistance Tester is mainly used to test contact resistance, sheet resistance, contact resistivity and other items. The platform size set by this function can measure 22 cut cells with a width of 6~10mm and a length of 230mm, using this function to measure solar cells can achieve fast, flexible and accurate detection. The line resistance test function is mainly used for the line resistance of grid lines. It can test cut cells with a width of 10mm and a length of 230mm. This function can also be customized for testing according to customer needs, and can provide customers with additional customized special platforms. The platform is equipped with vacuum adsorption equipment. Using this device for sample detection can ensure reliable sample positioning!

Sun Scan desktop software - user-friendly, convenient and practical

TLM Contact Resistance Tester uses Sun Scan interface software, which can switch between TLM and Line resistance modes. Photovoltaic enterprise users can set various required parameters in the parameter setting interface based on this interface software, and use TLM Contact Resistance Tester to measure the obtained contact resistance, sheet resistance, contact resistivity, and grid line resistance of the solar cell. Line resistance and many other performance parameters. It is used to evaluate whether the performance of its solar cells meets industrial standards and is displayed clearly and intuitively through the interface software. Solar cell manufacturers can understand the true performance of solar cells through the coordinate diagrams and data diagrams in the interface software!

The movement trajectory and measurement results of the probe head used by TLM Contact Resistance Tester will be displayed in the Sun Scan interface software at the same time, and the mode can be switched at will according to the needs of photovoltaic enterprise users. This software helps photovoltaic enterprise users optimize test methods extremely easily, allowing the Sun Scan interface software to perform analysis and generate fast and reliable reports.

Production and testing have always been a pair of important factors that are inseparable. Production must be matched with testing to maximize the use of solar cells. The TLM Contact Resistance Tester produced by Millennial Solar has been widely favored by solar cell manufacturers with its rigorous technical specifications and easy-to-use desktop software, thus helping them to produce efficiently! In the future, Millennial Solar will also work with many photovoltaic enterprise users to innovate products and empower new capabilities!
