In the production process of solar cells, whether it is using oxidation annealing process or thermal diffusion process, or depositing various types of thin film materials such as ITO films to improve the photoelectric conversion rate of solar cells, precise detection instruments are required to measure these solar cells are scientifically evaluated after the production process. Millennial Solar has produced Millennial Built-in Four-Point Probe Tester for this purpose. This equipment can quickly and accurately test solar cells after completing the deposition process and many other production processes related to solar cell resistance/resistivity. It is guaranteed to achieve a good contact rate while achieving zero fragmentation rate, and can generate real-time images of the detected data to intuitively and clearly present it, thereby providing strong assistance to solar cell manufacturers for large-scale solar cell production line production evaluation!

Millennial Built-in Four-Point Probe Tester - Testing equipment perfect for production lines

The most essential difference between Millennial Built-in Four-Point Probe Tester and Four-Point Probe Tester is that Built-in Four-Point Probe Tester can place itself in the production line to connect with production. After completing many production processes such as deposition process, oxidation annealing process and thermal diffusion process, the fully automatic 5-point and 9-point scanning measurement functions are used to measure large-scale solar cells.

In terms of detection technology, Millennial Built-in Four-Point Probe Tester is different from the traditional four-probe resistance tester. When the traditional four-point resistance tester performs performance testing on solar cells, it often comes into contact with solar energy. The surface of the cell is damaged and the solar cell is damaged. Even if efficient and accurate detection is achieved, solar cell manufacturers cannot successfully complete subsequent production. Millennial Built-in Four-Point Probe Tester perfectly solves this problem. It not only achieves precise testing of solar cells to obtain accurate performance parameters, but also ensures a good contact rate while achieving zero fragmentation rate. It is truly completed non-destructive testing!

The FPP230 Auto produced by Millennial Solar is a Built-in Four-Point Probe Tester specially designed for photovoltaic process monitoring. This device can quickly and automatically scan the sample to obtain the sheet resistance distribution information at different locations of the sample. Measurement dimensions can be customized according to customer sample size. 

●Measurement range meets sheet resistance of 1μΩ~100MΩ

●Able to match automation equipment and traceable at any time

●Perfectly connected with the automated production process of the production line

●Provide good electrical contact while ensuring fragmentation

●The number of measurement points can be customized according to customer needs

Highly efficient data collection—visualizing measurement results

The Smart FPP operating software used by Built-in Four-Point Probe Tester has an intuitive and friendly PC program that allows users to quickly characterize materials without writing any code. The software combines data collection with powerful analysis functions and has an intuitive visual interface. This function can be used on the equipment itself or independently of the production line.

Performance data measured by Millennial Built-in Four-Point Probe Tester can be displayed in 2D or 3D format, allowing for quick visualization of critical film uniformity data. Millennial Smart FPP software allows you to easily switch between individual measurement parameter distribution plots and rotatable 3D plots to provide an optimal view of customized process parameters. Ultimate product advantages and reliable after-sales service are key means to win the trust of users. Built-in Four-Point Probe Tester produced by Millennial Solar can rely on reliable detection functions, scientific detection technology, perfect connection with production line production and many other products. Help solar cell manufacturers to conveniently conduct large-scale solar cell performance testing. In the future, Millennial Solar will continue to adhere to the principles of quality and service, science and efficiency, and work together with many photovoltaic companies and their users to outline a photovoltaic blueprint!
