high performance 80tons/h ultra pure water equipment for the Production of Photovoltaic Cells

I. Overview
Ultra-pure water is an indispensable core element in the production of photovoltaic solar cells, with its purity directly impacting the photovoltaic conversion efficiency, yield rate, and long-term reliability of the cells. Ultra-pure water serves as the cornerstone of photovoltaic cell production quality (the purity of silicon wafer cleaning and texturing directly determines cell efficiency, with a 1% water quality defect resulting in efficiency loss ≥0.5%), cost optimization (advanced RO-EDI-polishing processes reduce unit water production costs by 40% and boost yield rates to >99%), and technological innovation (ultrafiltration membrane precision breakthrough (0.02 μm), nuclear-grade resin polishing, and nitrogen-sealed circulation becoming standard features of next-generation processes).
Industry consensus: Ultra-pure water equipment accounts for less than 2% of photovoltaic production line costs, but water quality defects can result in scrap losses reaching the tens of millions—“Water quality is the invisible lifeline of photovoltaic manufacturing.”
