Different from the traditional four-point probe tester, Millennial Built-in Four-Point Probe Tester provides a perfect connection with the automated production process of the production line, allowing it to smoothly perform the thin film deposition process on solar cells. Connect this production process and conduct scientific and effective testing of this production process to evaluate whether the process and the quality of the solar cells after the process have reached industrial production standards. The unique function of this device is that it uses four-probe technology that enables photovoltaic enterprise users to optimize electrical characteristics. It also monitors the stability of the manufacturing process in real time, and allows the solar cells to be scientifically inspected after completing the automated deposition process with the production line, and provides good electrical contact while ensuring zero fragmentation rate, achieving true non-destructive testing!

The sheet resistance/resistivity of solar cells has always been a parameter that photovoltaic cell manufacturers attach great importance to when putting cells into applications. The reason why solar cell has an ultra-high photoelectric conversion rate is often due to the deposition of ITO films or Various types of thin film materials are used. Built-in Four-Point Probe Tester produced by Millennial Solar can detect the sheet resistance/resistivity of the solar cell after depositing the thin film. Thus helping photovoltaic enterprise users carry out efficient production with scientific basis!
