Solar Silicon Ingot CrystalsMonocrystalline and multicrystalline silicon ingot & bricks for PV Manufacturing
Targray Silicon Ingot for PV Manufacturing
Targray is an industry-leading supplier of monocrystalline and multicrystalline solar-grade silicon ingot crystals & bricks for PV manufacturers. Committed to meeting the unique needs of each customer, we also develop custom silicon ingot solutions for photovoltaics production facilities 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 polysilicon feedstock used to produce our silicon ingots is of the highest achievable purity and consistency.
