Assistance Developing Photovoltaic Cleaning Process
Q: We are looking to hire someone to design and implement a turnkey cleaning process for our Photovoltaic manufacturing application. Do you provide this service?
A: Yes. We do this type of work often. With increased governmental commitments to support renewable energy initiatives, winners and losers in solar module fabrication will be determined more quickly and by a variety of factors. One factor will be the elimination of defects to increase yields in the manufacturing process. Critical cleaning of substrates and superstrates is an essential component in achieving an optimal solar module fabrication process which reduces the cost per watt.
Cleaning Stainless Substrates in Photovoltaic Manufacturing
Q: We need to clean stainless steel substrates prior to PV film deposition. What detergent should we use and in what amount and by what process?
A: If the process is batch ultrasonic cleaning, use a 2% CITRANOX® solution at 60°C for 5 minutes of dwell time in the tank. This approach can also be used when cleaning copper substrates.
If using a conveyorized horizontal washer where oily residues are a particular concern, use a 1% SOLUJET® solution at 60°C at line rates of 1.5 meters per minute, for a total contact time of roughly 30 seconds prior to the rinse station.
