Solargiga

Top player in Monocrystalline silicon solar ingot

The Group was principally engaged in manufacturing and processing of monocrystalline and multicrystalline silicon solar ingots and wafers as well as upgrading and trading of Multicrystalline. During the year, the Group has explored opportunities in the downstream business of solar cells production, including its module production and system installation.

By understanding the needs of downstream customers, the Group can also promptly develop new silicon solar ingots and wafers products needed by the customers, thus bringing synergy effect to the existing business of manufacturing ingots and wafers. Expanding both laterally and vertically, the Group has further strengthened its position to become a global solar energy enterprise.

As at 31 December 2010, the Group was equipped with 397 monocrystalline ingot pullers, 83 wiresaws and 4 multicrystalline casting furnaces, while the production capacity of ingots, wafers and solar energy photovoltaic module components have increased significantly, reaching 800MW, 600MW and 50MW respectively.

Crystalline silicon – the powerhouse of a solar cell

Monocrystalline silicon

Monocrystalline silicon or single-crystal Si, or mono-Si is the base material of the electronic industry. It consists of silicon in which the crystal lattice of the entire solid is continuous, unbroken (with no grain boundaries) to its edges. It can be prepared intrinsic. Most silicon monocrystals are in the shape of cylinders up to 2 m long and 30 cm in diameter, which, cut in thin slices, give the wafers onto which the microcircuits will be fabricated.

Monocrystalline silicon is used in the manufacturing of high performance solar cells beside many of its applications. Despite its availability at an affordable cost, it is still more expensive when compared to multicrystalline silicon.

Multicrystalline silicon

Multicrystalline silicon, also called polysilicon, is a material consisting...
