Baumer Improves Solar Cell Production With High-Sensitivity Near Infra-red Cameras

Baumer: The new TXG14NIR camera is one of a diverse selection of TX industrial cameras that solve several critical measurement tasks in the production of solar cells. With enhanced sensi-tivity in the near infrared (NIR), the TXG14NIR is especially qualified for automatic inspection of wafers for solar cells. Measuring electrolumi-nescence (EL) using NIR imaging cameras permits the detection of fractures as well as failures in the crystal structure. These images give information on the integrity and effective-ness of each wafer prior to the next processing step. The TXG14NIR camera provides a significantly higher sensitivity at the required wavelengths and, si-multaneously, provides high resolution images with 1392 x 1040 pixels. Structural defects within the wafer can be detected easily. Baumer’s innovative TXG14NIR cameras enable better inline process and quality control, helping optimize solar cell wafer fabrication.
