GT Solar Polysilicon Reactors

Polysilicon reactors convert purified TCS (trichlorosilane) feedstock into high quality solar grade polysilicon through a process of chemical vapor deposition on a heated filament. The SDR-100 is GT Solar's base model for high volume production. It delivers a low maintenance, high availability repeatable process platform intended for high volume manufacturing environments. The SDR-200 leverages key design improvements to increase yield by 33% compared with the SDR-100 (200MT/year vs. 150 MT/year.)

GT Solar STC Hydrogenation Unit

This unit converts STC (silicon tetrachloride) from the exhaust stream of the polysilicon reactor back to TCS using carbon reduction technology. The converted TCS is then recycled back to the polysilicon reactor for decomposition, allowing the plant to operate in an environmentally friendly closed loop and maximizing the productivity of the TCS feedstock.

Kayex Solar Crystal Growing Furnaces (mono-crystalline)

Kayex furnaces convert polysilicon feedstock into mono-crystalline silicon ingots for production of high efficiency solar cells. Kayex is the leading producer of Czochralski (or CZ) crystal growth proces furnaces given their high productivity and value; several product options are available depending on the client's desired output ingot diameter (up to 200mm and 150kg). The 100% automated control system delivers high repeatability, reliability, and flexibility.

GT Solar Directional Solidification System (DSS) Furnace (multi-crystalline)

The DSS furnace converts polysilicon feedstock into multi-crystalline silicon ingots for production of high efficiency solar cells. The market leader in multi-crystalline growth technology, this furnace allows ingots to be grown faster and at lower cost than ever before. Key design features ensure quick setup, operating convenience, and a fully automated process. Typical output ingot size is 84cm x 84cm and 400-450kg.

HCT Precision Wafering Systems (Applied Materials)

Applied HCT Precision Wafering Systems are designed to reduce solar cell costs by offering high throughput with minimum operating requirements. They can be used to produce either mono- or multi-crystalline silicon wafers in square, round or pseudo-square shapes; thickness of 100 to 350 microns; and throughput of 2 to 15 megawatts-equivalent per wire saw per year.

The full line includes the following components:

1. Cropper. Slices the tops and tails of mono- and multi-crystalline silicon ingots with minimal kerf (i.e., silicon) loss using a 250 μm-structured wire.
2. Squarer. Slices (a) cast multi-crystalline silicon ingots into bricks, or (b) pulled mono-crystalline silicon ingots into pseudo-square bricks, both with superior surface quality (no further grinding required) and kerf loss near zero.
3. Wire Saw. The E500SD-B5 Wire Saw slices mono and polycrystalline bricks into wafers, including thin and ultra thin wafers, with high mechanical accuracy and high throughput and load capacity.

Despatch Infrared Furnaces for PV Cell Manufacturing

Despatch infrared furnaces help photovoltaic cell manufacturers increase output while lowering the cost of production. Every Despatch furnace is designed for high cell efficiency and delivers maximum production up-time, high throughput and yields, and minimum maintenance cycles.

1. Diffusion Systems
   1. Integrated, In-line Diffusion System. The DCF Series In-line Diffusion Systems represent an important advance in solar cell manufacturing by integrating into one piece of equipment.
      1. A patent-pending, in-line phosphorus doping module
      2. An infrared diffusion furnace featuring a patent-pending thermal processing chamber
      3. Critical process technology required to produce highly uniform emitters.
      DCF Series Infrared Systems are designed to create highly homogeneous, shallow emitters that are critical to manufacturing high efficiency solar cells. The drive toward thinner wafers and higher yield make these systems ideal for maximizing your future investments.
   2. In-Line Diffusion Infrared Furnace. Despatch DF Series infrared furnaces are designed for in-line phosphorus diffusion of multi- or mono-crystalline silicon wafers. These highly efficient in-line diffusion furnaces are available in laboratory or full production scale systems and are designed to meet today's requirements for high efficiency, shallow emitters.
2. Drying and Firing Systems
   1. Firing and Drying/Firing Furnaces. Despatch CF and CDF Series infrared furnaces are designed for very rapid ramp rates, which optimizes contact formation on silicon wafers with shallow emitters and silicon nitride coating. Rapid heating and cooling allows firing the contact through the silicon nitrate while rapid cooling prevents damage to the junction. This requires faster belt speeds which enhances throughput as a secondary benefit. CF series infrared firing furnaces perform the complex thermal profiles needed for effective contact formation, while CDF series dryer/firing furnaces are designed to integrate the metallization paste drying step with the critical firing step, reducing material handling breakage and redundant component costs.
   2. Dryers. Despatch DR Series infrared drying ovens are designed for fast, efficient drying of screen printed metallization paste materials used to form the front and rear side contacts, as well as the full back side field, on multi- or mono-crystalline silicon solar cells. In-line dryers eliminate material handling resulting in reduced breakage rates and downtime.
