Targray Silicon Ingot for PV Manufacturing
Targray is an market leading supplier of monocrystalline & multicrystalline solar silicon ingot crystals and bricks for photovoltaics manufacturers. Committed to meeting the unique needs of each customer, we also develop custom silicon ingot solutions for photovoltaics manufacturers and technology developers with highly specific project requirements.
Monocrystalline wafers generally have a higher efficiency conversion rate of sunlight to electricity. However, in both monocrystalline & multicrystalline crystallization processes, feedstock quality is a critically important issue. Focused on minimizing investments and operational costs for PV manufacturers, we work closely with partners to ensure the highest consistency & purity polysilicon feedstock is used to produce our line of solar silicon ingots.
