Fraunhofer Center for Silicon Photovoltaics CSP- Laser-induced plasma spectroscopy can be used to examine samples (including those of non-uniform shape) up to a size of 30 cm x 40 cm. 2D mappings over the entire surface can be created, and element contents in materials can be quantitatively determined using appropriate calibration standards.
- The tool is inline capable, so that analyses directly on a conveyor belt are also possible.
- We offer standardized order analyses as well as complex root cause analyses, from single orders to extensive research and development projects.
Laser-Induced Breakdown Spectroscopy
2D Mapping
LIBS analysis as a 2D mapping is used to visualize the lateral element distribution.
- Display of element distributions over large sample areas (up to 30x40 cm)
- From smooth samples to uneven surfaces
- Measuring spot 100 µm
Quantitative Analyses
Laser Induced Breakdown Spectroscopy (LIBS) enables in-line analysis of element contents.
- Quantitative analyses from the % range to the ppm range
- Reference materials required for calibration of the analysis
- After extensive method development, sample analysis is possible in seconds
PV Recycling
Inline-capable LIBS analysis is used to determine the composition of recycled materials.
- Identification of fluorine-containing backsheets for process optimization
- Determination of precious metal contents in primary recyclate
- Composition of solder pastes and contact fingers
