100% PID Free, Multi-Crystalline PV Cells

We manufacture 100% PID Free and one of the highest efficiency cells in the world. The average efficiency of our cells is 18.30%.

Our Cells are made of Virgin Poly-Silicon Wafers and Silver bus bars. The CTM ratio of our cells is ≤ 1.0%

We offer both 3 BB and 4 BB Cells.
