New for Chinese PV industry: Camera-based quality inspection systems for retrofitting cell testers/sorters with inline color classification

German machine vision expert VITRONIC presents quality inspection systems at SNEC in Shanghai

(PresseBox) (Wiesbaden, )
The demand for high quality solar cells is increasing worldwide. This imposes pressure upon cell producers to sort cells reliably and fully automatically. Camera-based quality inspection and cell classification can be integrated into existing cell testers/sorters. At SNEC 2013 VITRONIC presents to the Chinese PV industry its VINSPECsolar VCOFLC1 camera system that enables exact and reliable front print and color inspection, better than human eyes can do.

Tier One customers require high quality solar cells. Especially sorting into different color classes is a main scope at Asian factories. Therefore many Asian solar cell producers consider how to retrofitting their existing production plants. The new VINSPECsolar VCOFLC1 camera system combines front print and color inspec-tion, and performs exact and reliable quality inspection and cell classification. VINSPECsolar VCOFLC1 enables easy operation, calibration and reliable and robust performance at competitive pricing. VITRONIC provides a standard calibration tool to define the color classes and borderlines. Even if several cell testers have to be operated and tool matching is required: the set up process needs to be done only once and the classification rules can be copied to all other testers.

The inspection system can be used for both mono and multicrystalline silicon cells. Its throughput achieves more than 2,400/h, and the sorting pureness is higher than 99.8 percent. The sensor box consists of a color line scan camera with four 4,096 (4k) pixels lines, a white LED illumination module, a backlight and a computing subsystem. The software – developed by VITRONIC - provides automated, fast tool calibration and tool matching, a graphical user interface comprising yield control tools for rapid intervention and process adjustments, statistics and visualization of all quality relevant features of current and recently tested cells.

VINSPECsolar - Inspection of solar wafers, cells and modules

VITRONIC Dr.-Ing. Stein Bildverarbeitungssysteme GmbH

As one of the largest independent suppliers of optical inspection systems for the photovoltaic industry, VITRONIC has been active in Asia for many years. Many renowned solar cell and module manufacturers use inspection systems for inspecting wafers, solar cells and modules. Camera systems are used along the entire process chain, from wafer production to cell production, all the way to module production. VITRONIC offers a customized solution for all relevant production steps.

Several hundred camera-based inspection systems from VITRONIC are already installed in Asia; in fact, there are over 120 camera systems in one major production plant alone. Worldwide, some 1,000 inspection systems are installed at about 70 customers. In 2012 VITRONIC established a subsidiary VITRONIC Machine Vision (Shanghai) Co. Ltd - to provide the same high level of customer support for our growing customer base in China, as the many renowned customers worldwide rely on since years.
