GP Solar of Constance is expanding its product portfolio with inspection systems for thin film solar modules, and thus introduces one of the first fully integrated quality measuring systems to the market. The product line, which is specially adapted to thin film technology, is highly flexible and seamlessly integrates into existing product infrastructures with clearly defined system interfaces. The inspection systems can be installed at any point along the production line.
During production itself, the most minute defects can be detected, thus reducing rejection rates. Measured data is evaluated in near real time through the use of next-generation image processing technology, and each individual module can be inspected if necessary. This GP Solar development can even accommodate the trend toward ever larger modules. High-resolution defect analysis systematically examines large areas down to a resolution of 25 microns (equates to three gigapixels) - even the smallest defects are visible.
"Our long years of competence in crystalline photovoltaics measuring technology stood us in good stead as we developed our thin film inspection product line," explains GP Solar managing director Dr. Eric Rüland. "To reduce costs, targeted defect analysis and classification is a must in the field of thin film. We help our customers in the middle term to make their modules a real alternative in a market previously dominated by crystalline cells."
GP Solar shows its in-house development competence in its successful combination of optical and sensor-based processes. For instance, the thin film measuring technology employs a special X-ray fluorescence (XRF) measuring head for precise material analysis.
This thin film measuring technology extends the GP Solar Inspect product line and consists of three different types of products.
The GP TF-EYE is an optical inspection process for large surfaces based on cutting-edge image processing technology. GP TF-SENSE and GP TF-SENSE SCAN permit the use of contactless point sensors for analyzing electrical and optical characteristics, as well as material composition following individual production steps. This is where X-ray fluorescence measurement comes in.
The GP Solar Inspect product line for thin film inspection will be presented at the 25th European Photovoltaic Solar Energy Conference and Exhibition in Valencia, Spain. The GP TF-EYE system will be demonstrated at the exhibition booth and is available immediately. Delivery time ranges from six to eight months, depending on the system configuration.
