Solar Grade Chunk Polysilicon

Solar Grade Chunk Polysilicon-Solar Grade Chunk Polysilicon

Sipariş No : Solar Grade Chunk Polysilicon

Medium to extra large solar-grade polysilicon chunks made from dedicated Siemens reactor runs. Breaking into chunks and packaging are performed in clean room environment and care is taken to minimize introduction of surface contamination during the breaking/packaging processes. Small amount of pop-corn surface is allowed. No carbon ends (graphite electrodes) are included.

Solar Grade Chunk Polysilicon


We utilize a closed-loop modified Siemens process to produce high quality polysilicon. We have implemented a quality management system to ensure the quality of our products. We are currently applied for successfully combined the strong industry know-how with our in-house expertise, and several patents based on our innovation.

Medium to large blocks of solar-grade polysilicon are produced using our chemical vapor deposition process reactors. To avoid surface contamination we fragment and package our Polysilicon crystals in our clean room.
