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.”
II. Process
Raw Water → Pretreatment → Two - stage RO → EDI → Polishing Mixed
Bed → Terminal Refinement
