Solar Cell Production: Wet Chemical Monitoring of Texturing Processes
Jan 20 2010
ProcessLab is a robust, easy-to-use analyser that is installed directly at the process line. All that is required is taking a sample and selecting the parameters to be determined. Crucial parameters of texturing baths such as content of the various acids as well as alkaline components are determined fully autonomously. This means efficient and direct process control right on site, day and night and over all process stages.
Texturing and rinsing processes are the core of solar cell production. Analytical control of these steps is essential. ProcessLab enables precise monitoring of relevant bath components, allowing the production process to be run with maximum efficiency: consumption of chemicals is reduced while throughput is increased, resulting in higher yields and lower running costs. ProcessLab is customised to the specific requirements and is the optimum solution for:
• Analysis of acid mixtures like HF, HNO3 and H2SO4 • Control of treatment baths containing e.g. H2O2 and KOH
• Full analysis of alkaline and acidic texturing baths • pH and conductivity measurements in all process baths
• Determination of complexing agents as e.g. NTA or EDTA
