Virtual Industries, a supplier of manual vacuum handling solutions, has made available its new general-purpose wafer vacuum handling tool, ‘WAFER-VAC’ system with 8” molded wafer tip (WV-9000-MW8).
Start-up Sol Voltaics has unveiled ‘SolInk’, which is claimed to be an economical nanomaterial that promises to increase the efficiency of crystalline silicon or thin-film solar modules by up to 25% or more. Gallium arsenide nanowires are fabricated via a high-throughput process called ‘Aerotaxy’ invented by company founder and Lund University professor Lars Samuelson.
PPG Industries flat glass business unit has said that it can now manufacture heat-strengthened glass in thicknesses of less than 3mm, which makes it among the first major glass manufacturers in North America to offer this capability. PPG offers the SOLARPHIRE glass in heat-strengthened configuration with thicknesses of 2, 2.5 and 2.7mm.
The Dow Chemical Company has developed a diamond wire ingot squaring coolant that improves PV wafer manufacturing efficiency while also improving the sustainability of the production process. ENLIGHT DC-8300 is water-based and provides better cutting precision and efficiency.
Vesuvius, which provides an extended range of refractory products used in the manufacturing of thin film and polycrystalline solar panels has introduced the ‘SOLAR Crucible MLC,’ a crucible used for the fusion and the crystallization of polysilicon in the manufacturing of mono-like silicon ingots. The system has been specially engineered to match mono-like special requirements.
A thermoplastic encapsulant from Wacker, ‘TECTOSIL’ has proved to offer protection against potential-induced degradation (PID), according to tests carried-out by Photovoltaik-Institut Berlin. The testers confirmed that such modules do not display leakage currents due to PID when using the thermoplastic silicone elastomer sheet in the encapsulation of PV modules.
The RENA RS 690-DW was developed to achieve diamond wire sawing with highest wafer quality at the lowest Cost of Ownership (CoO). Depending on process parameters a claimed throughput greater than 15 MW/a can be realised. Features such as optimised wire guide axis distance, high wire speed and reduced cutting time are designed to support improved wafer quality and throughput.
ISRA SOLAR VISION, a business unit of ISRA VISION AG, is featuring a new generation of contactless photoluminescence (PL) inspection systems, including the high-accuracy, high-speed inspection of solar cells and wafers. The new SOLARSCAN-YIELDMASTER PL is claimed to provide the industry’s fastest contactless photoluminescence inspection with the lowest false detection rates and the most accurate defect classification for the mass production of solar cells.
DuPont Microcircuit Materials (MCM) has introduced its next-generation frontside metallization pastes for crystalline silicon solar cells. ‘DuPont Solamet PV18x’ series photovoltaic metallization pastes are claimed to offer PV manufacturers improved productivity beyond that provided by the ‘Solamet PV17x’ series. ‘Solamet PV18A’ is claimed to be the first metallization paste tailored for optimal performance on mono-crystalline wafers with enhanced Lightly Doped Emitters (LDEs).
DUNMORE Corporation has developed a new version of its DUN-SOLAR TPE solar module backsheet. TPE provides the proven performance of DuPont ‘Tedlar’ polyvinyl fluoride film in a construction that exceeds current market requirements for longevity and total cost of ownership.
