With the development of photovoltaic technology, cell manufacturers have higher and higher requirements for the quality of photovoltaic cell parts and the accuracy of measuring instruments. In order to adapt to the pace of development of the times, "Millennial Solar" according to customer needs, developed a fast, two-dimensional, high-precision measuring instrument——Automatic Image Measuring Instrument, which is used to measure photovoltaic cells such as TOPCon, HJT, perovskite and PERC, so as to help photovoltaic enterprise users improve the screen printing process in the cell production process!

High-quality Cells Are Not Far Away From Us

Millennial Automatic Image Measuring Instrument is equipped with a measurement system based on high resolution, which can be used to detect the pattern, 2D plane, and grid line width, spacing, printing effect and so on of solar cells so as to produce high-quality grid line electrodes to achieve the purpose of reducing the shading area, improving the battery JSC, and improving the efficiency of solar cells.

Excellent Optical Technology

Millennial Automatic Image Measuring Instrument uses an advanced optical system with 2 million high-definition pixels, equipped with automatic zoom lens and auxiliary lens, which can reflect 25-345 times video magnification on the computer display.

Millennial Automatic Image Measuring Instrument has the feature of automatically identifying the edge of the solar cell. The LED light source used can automatically adjust to the appropriate light source according to the lens magnification to improve the use efficiency. Thereby reducing errors between operators and consistency errors between instruments.

Accurate and Fast Focusing Function

Fast and accurate focusing is the key step to ensure the clarity of the measured image. Millennial Automatic Image Measuring Instrument can focus on the grid lines of photovoltaic cells in the fastest 1S, and the focusing repeatability can reach 0.002mm~0.003mm, and Introduced sub Pixel measurement function.

Subpixel is the smallest unit of the imaging surface of an area array camera, and the distance between pixel centers ranges from several to tens of microns. It can maximize the use of image information to improve resolution, and the sub-pixel measurement function can help beginners better observe the entire sample in real time, realize rapid product positioning, accurate measurement, and improve measurement efficiency.

Exclusive Metal Coverage Measurement

VMM PRO metal coverage refers to the area ratio of grid lines covering the entire photovoltaic cell.

Millennial Automatic Image Measuring Instrument can calculate a large amount of measurement data by moving the photovoltaic cell once, so as to complete high-precision cover scanning, and automatically identify the grid line area in the system software according to the scanning information, finally, the identified gridline area is calculated and divided by the total substrate area to obtain the metal coverage.
