Solar Wafer Cleaning
Solar Wafer Cleaning Systems | Higher Purity, Cleaner Wafers= Improved Yields
Remove contaminants and saw contamination to improve yields
Purity of wafers and cells is critical in the PV manufacturing process. High purity levels are required in raw materials. In research and in production, contamination is an issue. Oxide growths (especially during drying), metal impurities, handling contaminants and saw contamination can impact yields. In wafer production, slurry removal and deglue has a significant impact on yields and costs. High performance solar wafer cleaning is critical. MEI is your partner in maintaining purity with high throughput, automated solar cleaning, whether you’re doing research or in high volume production.
