High purity silicon feedstock for solar-grade polysilicon, ingots, wafers and PV cells.
Solar energy begins with silicon. Silicon metal is refined into solar-grade polysilicon, which is then cast into ingots, sliced into wafers and processed into photovoltaic cells and modules.
Purity is decisive for solar performance: even trace impurities reduce cell efficiency. We supply low-impurity silicon metal and high purity silicon powder (3N–5N) to support consistent, high-yield solar material production.
