Citranox Corrosion for Photovoltaic Application
Q. We use Citranox for cleaning glass coated with tin oxide. We use the cleaned glass to deposit thin film CdS/CdTe photovoltaic devices. We use your citranox detergent and use a stainless steel ultrasonic cleaner. Is there a concern that the citranox could corrode stainless and deposit metallic ions on the glass surface? Which can be detrimental to the semiconductor films of the photovoltaic devices? Should we use a PTFE ultrasonic cleaner?
Using a Miele Washer
Q. I was curious if Solujet and Liquinox are interchangeable? We are a medical device company that currently uses Liquinox to wash glassware by hand, but recently got a Miele glassware washer and want to use an Alconox product in it.
A. Solujet will give comparable cleaning performance in a Miele washer to manual cleaning with Liquinox.
Advantages of Properly Cleaned Glass Substrates
Q. I have previously worked on CdTe solar cells in academia and DSC in industry and currently work with industry on collaborative R&D projects across materials science. I would like further information on the advantages of properly cleaned/prepared glass substrates and it’s effects of module/cell performance.
Removing Latex from Optical Cuvette
Q: How do I remove latex particles from an optical cuvette.
A: We recommend you use a warm 1% Alconox detergent followed by a warm water rinse to clean the optical cuvettes.
Aqueous Cleaning Environmental and Safety Issues
Q. What are the environmental health and safety issues that need to be considered when developing an aqueous cleaning process? A. Aqueous cleaners, by definition, use water for cleaning and rinsing. This has both advantages and disadvantages.
