Solar inverters

SOLIVIA solar inverters produced for the North American market will be presented for the first time to the public at the Intersolar tradeshow in San Francisco. Four new models Ð SOLIVIA 2.5, 3.3, 4.4 and 5.0 NA G3 Ð with a nominal output power ranging from 2.5 to 5.0 kW complements our already available European solar inverter product line from Delta. Production will begin in the fourth quarter of 2010. The high-frequency grid-connected SOLIVIA solar inverters from Delta are suitable for all commonly used solar modules — also for thin-film and rear-side contact PV modules — due to the implemented galvanic isolation and the integrated DC wiring box that accommodates either positive or negative DC grounding. All models incorporate an integrated lockable DC disconnect which is mandatory for many local authorities, leading to reduced installation efforts and expenses as it eliminates the need for an external 600 Vdc disconnect switch. The high-frequency grid-connected solar inverters for the North American market operate within a wide temperature range, up to 50 degrees C with full power output (without derating). This ensures high yields even for installations in warmer climates. With its intelligent MPP tracking the inverters get maximum energy harvesting from the solar modules under all operating conditions. The SOLIVIA inverters feature a lightweight, compact design and simplified installation by using the unique mounting plate that is provided. In addition, the SOLIVIA inverters are NEMA4 / IP65 enclosure rated for dust-tight operation, completely safe to touch and protected against moisture, allowing the models to be installed indoors as well as in protected outdoor areas. All relevant status messages and stored data can be recalled either via the integrated display or via a PC connected to the RS485 communication interface.

GXS dry pump for solar crystal puller and laminator apps

Edwards, vacuum and abatement equipment and services provider, debuted the GXS dry pump, designed to support pumping requirements for silicon ingot manufacturing and laminator applications in the solar industry. The GXS optimizes thermal control and dust handling for challenging pumping processes. The high atmospheric pumping speed capability also enables faster chamber pump down. The dry pump suits the specific pumping process requirements for solar laminator and crystal pulling applications, said Allister Watson, Ph.D., solar and flat panel display dry pump product manager at Edwards. “Its closed-loop thermal management system ensures the pump remains at a temperature to prevent pump seize-ups, due to either glue condensation in laminator applications or overheating when pumping high concentrations of argon during crystal pulling applications. At the same time, its fast pump down time, low utility consumption and reduced maintenance all contribute to a low cost of ownership.” The GXS uses a tapered variable pitch screw profile (patent pending) that allows for tight clearances without the need for rotor coatings. It also enables compression variations along the rotor axis for improved thermal stability and better thermal control, making it an optimal pump to handle the high flows of argon gas used in crystal pulling applications, as well as the dust generated during the manufacturing process. The GXS dry pump can operate on as little as 3.9 kW of input power (depending on the pump version) and reportedly uses 57% less energy than competing piston pumps. The high-efficiency motors are inverter-driven and enable reduced energy by running in idle mode. Inert, non-oxidizing oil is used to lubricate the gears and bearings of the pump with no maintenance required between major services and no oil changes. The dry pump features a small footprint (approx. 0.4 × 1.1 × 0.8m) and low noise (<64 db[A]), which allow pumps to be located close to customers’ chambers, if required. The GXS pump is compatible with Edwards Fabworks data monitoring system so that pump parameters can be monitored and trended in real-time via a central computer.

Continuous horizontal tube furnace

Koyo Thermo Systems, a leading manufacturer of furnaces and ovens for the semiconductor, solar and LCD industry, announces the sales launch of a new continuous horizontal tube furnace for POCl3 doping of silicon wafers and crystalline solar cells. Until now phosphorous doping of solar cells had to be done in a non-continuous process in a horizontal tube furnace or in a special conveyor furnace. The horizontal furnaces need a large footprint and much time for loading and unloading is used. On the other hand, the conveyor furnaces cannot work with doping gas. Additional process steps like printing a doping paste on the wafers and removing it after thermal treatment are necessary. As the first furnace manufacturer, now Koyo Thermo Systems merged the benefits of both systems and developed a continuous tube furnace which can use POCl3 doping, has a low foot print, high throughput, low energy consumption and reasonable price. Today Koyo Thermo Systems presented this brand new furnace at the solar exhibition PVJapan 2010 in Yokohama. Koyo expects, that this new model will be a break through in doping technology. This furnace can help to reduce production costs of crystalline solar cells further and this is a key issue in the development of alternative energies and it can be used also for doping of semiconductor wafers in IC manufacturing. Koyo had done pioneering work for doping solar cells before already. A modified conveyor furnace with wire transportation system had been developed, which could offer an improved temperature uniformity during doping and same time reduce energy consumption, compared to the conventional mesh belt transportation furnace. Koyo Thermo Systems is a subsidiary for JTEKT, Intersolar North America 2010, Moscone Center, West Hall.

High purity, Kimura elastomers

Perlast Ltd, a unit of IDEX Corp., is further lowering the cost-of-ownership of Etch and chemical vapor deposition (CVD) process equipment with the launch of new Kimura K23X and K2CD elastomers. Kimura K13X, and now K23X and K2CD elastomers, feature a proprietary, self-reinforcing polymer structure that avoids the need for traditional and organic fillers. As such the elastomer addresses the particulation and thermal expansion issues that can arise with fluoroelastomer (FKM) and high purity perfluoroelastomers (FFKM) seals in Etch and CVD processes. Kimura’s absence of a filler, even an organic one, reduces the speed with which the elastomer is degraded by aggressive process plasmas, enabling Kimura seals to last up to 40% longer than FKM and FFKM seals in both hot and cold processes. The Kimura elastomer’s low thermal expansion enables the Kimura seals to be retro-fit into existing O-ring glands designed for FKM and FFKM materials in older etching chambers. Moreover, the new technology elastomer exhibits low ‘stiction’ in dynamic applications such as L-motion gates, door seals and throttle valves, as compared with FFKMs. At the sub 45nm feature level, high purity perfluoroelastomers are reaching their operational limit. It is here that Kimura’s extremely low levels of particulates give manufacturers a clear productivity edge. Designed specifically for sub 45nm features semiconductor architectures, the Kimura K23X and K2CD materials enable engineers to significantly increase CVD and Etch equipment productivity. “Kimura K23X and K2CD continue to drive the ‘purity with performance’ agenda in semiconductor equipment sealing,” says David Holt, sales director, Perlast Ltd. “The new elastomer grades build on the success of Kimura K13X in Etch processes where it has provided unprecedented levels of service; and broaden the scope for Kimura to reduce equipment cost-of-ownership in CVD processes as well.” Perlast Ltd, Intersolar North America 2010, Moscone Center, West Hall, Level 2, 8217.

Flexible thin film inspection

Xiris Automation Inc., a 20 year veteran in the machine vision industry, has developed TFI-FLEX, an inspection system used for detecting defects in Flexible Thin Film Photovoltaic Cells. Designed for in-line quality control use by manufacturers of Flexible Thin Film Cells, TFI-FLEX is capable of detecting defects in surface quality and chemical deposition of cells at multiple points along a production line. The TFI-FLEX Inspection System performs visual checks on the activated side of a flexible thin film cell, looking for defects that are specific to quality issues arising from the handling and manufacture of thin film cells, including topological defects such as scratches, bumps and dents; and print/deposition defects such as chemical deposition flaws, stains, spots, watermarks, fingerprints, and color variations. The system uses a proprietary method of acquiring images with very low optical distortion in color and/or monochrome mode, detecting defects that are much smaller than 1 mm in size. TFI-FLEX is an important new tool for inspecting cells after deposition, after laser etching, after printing, and after final environmental coating of the cells. The system can easily be retrofitted into existing lines and can be configured to include multiple inspection modules (each with a solution-optimized design).
