At this year’s 26th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC: 5. – 8. September 2011 in Hamburg) GP Solar GmbH presents its latest product line for inline measuring technology with numerous hardware and software improvements. A proprietary development in the field of camera optics enables optimized defect detection by spectral analysis of wafers, cells, and modules, providing the highest degree of measurement accuracy for innovative processes, such as those used for manufacturing selective emitters and back-side contacts. The new software development simplifies the set-up of new recipes, allows individual fine tuning of the print set-up and enables defect analysis of up to 600 samples, making minute process problems visible. Now, the software is also available with a Chinese user interface.
GP TOPO-D .Scan is a global first. It is an inline inspection device for full-surface 3D topographic measuring of wafers and solar cells. Measurement is performed within a second without stopping the production process. The height resolution of the measurement is 4 µm at a lateral resolution of 160 µm on standard belt conveyor systems. The system detects saw marks on wafers as well as three-dimensional print defects on solar cell rear sides.
The GP TF-SENSE .Scan is a high-quality inspection system for 100 percent inspection of thin film modules. Due to advanced sampling automation each individual substrate can be measured without affecting the production cycle.
The integrated Fischerscope® XRF sensor is optimized for continuous material analysation and ensures a customized detection of CIGS layers.
The ability to detect the smallest defects immediately is an attribute common to all of these innovations. “Due to falling prizes solar manufacturers are pressured to reduce costs and introduce new and more efficient solar cell processes. The new GP Solar inspection systems optimize process control in production and improve the cost structure significantly,”
explains GP Solar’s Managing Director Dr. Eric Rüland.
The inspection systems are all capable of flexible deployment into production lines, as well as being easy to integrate and up and running quickly.
