Situation
In modern solar cell production, wet-chemical baths are used for a broad range of process steps. Detailed processes knowledge and precise knowledge of wet chemical solutions’ chemical composition form the basis for reliable process control. The GP PROCESS-LAB precisely and automatically analyzes almost all chemical compositions in wet chemical baths used in acid texturing processes for solar cell production.
Principle
- Automatic sample preparation and analysis
- Acid-base titration
- Select measuring method using a barcode on sample bottle
Advantages
- Chemical composition knowledge increases line performance and bath life spans
- Better understanding of processes
- Automatic offline measurement
- One measuring device can analyze various baths (various chemicals)
- No calibration necessary
- Advanced version for edge isolation bath analyses and analyses of advanced acid texture baths with H2SO4
