product news ♦ Equipments and materials
many of these companies have grown to become some of the region’s largest solar manufacturers in China, Korea, and Taiwan, and are using GT Solar products and technologies to improve productivity and lower their cost of manufacturing.
In September of 2009, the company opened its facility in Shanghai, China to provide greater service and support to its growing customer base in the region. The Shanghai facility will continue to provide installation resources, demonstration capabilities for customers wishing to test new process recipes, product training and spare parts inventory. PV equipment product development, engineering and R&D will remain in the company’s corporate headquarters in Merrimack, New Hampshire, and product development, engineering and R&D for its polysilicon equipment will remain in Missoula, Montana.
GT Solar also announced today that its next DSS crystalline growth furnace, the DSS650(TM), has begun beta production evaluation with customers. The new system provides an upgrade path for current customers using DSS 240(TM), DSS450(TM) and DSS450HP(TM) systems in their production environments. The DSS650 is capable of producing ingots larger than 600 kilograms and is compatible with the chamber configuration of current DSS systems. Commercial availability of the new system is expected for early calendar year 2011.
“The DSS650 continues our commitment to customers to lower their manufacturing costs by leveraging their investment in our crystalline growth furnaces to take advantage of new technology,” continued Gutierrez. “We designed the new DSS650 system so current customers can easily upgrade to the new system, which underscores our commitment to protecting our customers’ investment in GT Solar DSS equipment.”
With over 1,700 systems in the field, GT Solar’s DSS ingot growth furnaces are widely used in PV wafering operations. GT Solar’s innovation and expertise in mechanical design, vacuum and high- pressure chambers, control system design, and crystal growth modeling, provide customers with a technologically advanced directional solidification furnace that consistently produces high quality ingots with optimized mass ingot yield.

Hiden Analytical launch real-time multi-species gas
analyser Hiden Analytical introduce the new QGA compact benchtop mass spectrometer configured for continuous real-time multi-species analysis of both gases and vapours in the pressure range from 2 bar to 100mbar absolute
Applications include thermal analysis, fermentation processes, catalysis and general gas reaction studies.
With mass range to 300amu and detection levels to 100ppb the system features the QGA operating program for quantitative analysis of up to 16 gases and vapours, together with an internal 10-peak spectral library and automated spectral overlap correction. Data is readily integrated in real time with external monitors including temperature, pressure and weight and with external gas monitors for applications such as CO monitoring in the presence of N2. The innovative APSI mode reduces molecular fragmentation by soft ionisation to refine analysis of complex organic molecules and enables selective ionisation of many gas species by selection of specific ionisation energies – helium and deuterium at mass 4 for example.
The flexible 2M long sample interface operates to 200C and is configured to balance sample consumption to the process requirements with sample consumption rates controllable from 1 to 16 mL/min. Options include high-pressure adaptors for sample pressures to 30 bar, gas stream selectors for selection from up to 80 gas streams and hot- zone extensions for direct sampling from processes to 1000C.
