Targray products

Raw Polycrystalline Silicon Materials for PV Manufacturing; Raw polycrystalline silicon, commonly referred to as polysilicon, is a high-purity form of silicon which serves as an essential material component in the solar photovoltaic (PV) manufacturing industry. It is the primary feedstock material used for the production of conventional solar cell today. Polysilicon feedstock generally consists of large rods which are broken into chunks or chips of various size, then cast into multicrystalline ingots. The ingot materials are subsequently sliced into silicon wafers suitable for solar cell production.

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.

Targray offers a full range of monocrystalline and multicrystalline solar cells for commercial-scale solar module manufacturing. Through our extensive global partner network, we have a reliable supply of high quality mono & multi solar cells to support both short term and long term production requirements. Our high-efficiency PV cells are suitable for a broad range of module applications including private rooftop installations, commercial and industrial rooftop installations, remote power generators and large-scale power plants on the ground and on the water. Targray is committed to helping our customers reduce their overall cost per watt (Cost/Wt) and create new business efficiencies. This commitment is reflected in the quality of our solar cells, which have been designed and manufactured to the highest standards of performance and durability. Our cells are tested under the toughest PID-free testing conditions and certified by institutions such as UL and ITRI.

Targray monocrystalline solar cells are ideally suited to the evolving needs of today’s photovoltaics industry. Trusted by solar PV manufacturers around the world, our mono c-Si cells are manufactured using best-in-class raw materials and subject to strict quality control.

Mono PERC solar cells have paved the way for significantly increased efficiency over standard monocrystalline cells. Central to PERC (Passivated Emitter Rear Contact) technology is the combination of rear wafer surface passivation and local rear contacts, a process which delivers significant efficiency-enhancing benefits, particularly at the PV system level.

Targray offers a full range of solar silicon wafers for solar cell production. Through our extensive global partner network, we have access to a reliable supply of high quality solar wafers to support both your short and long term product requirements. Our high quality solar silicon wafers can be manufactured to your exact specifications, with custom options for thickness, geometry, bevel edge and more. Working with our suppliers and trade associations like SEIA we help PV manufacturers increase their product efficiency while also minimizing soft costs. Our solar wafers are supported by a range of supply chain finance and inventory management programs designed to optimize material procurement.

Solar ribbon, also known as PV tabbing ribbon, is a copper conductor installed in photovoltaic solar panels. The ribbon is soldered directly onto silicon crystals to interconnect solar cells in a solar module. It plays an important role in determining cell efficiency, carrying the current generated in the solar cell to the PV bus bar. Targray’s solar ribbon materials portfolio meets the stringent requirements of commercial PV manufacturers today. Characterized by their excellent uniformity, solderability, and elongation, our solar tabbing ribbons can deliver a yield rate upwards of 98.5%, enabling manufacturers to increase productivity while keeping manufacturing costs low.
