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.
PSE AG has developed a new test stand, Degratest Labtool, designed for the testing of the light-induced degradation (LID) effect on silicon solar cells. The testing technology monitors and records degradation effects, and offers manufacturers and research institutions a fast and reliable tool for testing and developing solar cells. The LID test system was developed at ISC Konstance.
Datapaq has launched a tailored version of its SolarPaq temperature profiling system for contact paste drying processes.
Scanlab has broadened its offering with ‘SCANalign,’ a vision system tailored specifically to the demands of laser processing steps used in solar cell fabrication steps.
Meyer Burger’s patented ‘SmartWire Connection Technology’ (SWCT) is designed to replace conventional silver-based busbars on solar cells using thin copper wires on both sides of the cell. Typically, 30 very fine copper wires are used for cell connection generating up to 2,000 contact points per cell that provide 5% higher power output compared to best-in-class 3BB (three busbar) technology, while reducing production costs.
SoLayTec has introduced its InPassion ALD (Atomic Layer Deposition) tool for depositing Al2O3 in mass production. Al2O3 is well known in the PV community for highly effective surface passivation properties and negative fixed charge density, which is required for thinner wafer usage. InPassion ALD tool is capable of processing up to 4,500 wph.
With the SamBa series of low-light cameras, Sensovation is able to offer sensitivity in the near-IR range at high speed that enables industrial testing applications such as electroluminescence imaging of solar sells and modules. SamBa Ci is a 2 MPixel, high sensitivity camera optimised for high-throughput EL-based inspection.
The ‘Safire’ firing furnace, together with the ‘DriTech’ dryer, were designed by Despatch Industries to provide PV manufacturers with the ability to properly segment, control and adjust key process parameters. The Safire design features dual, independent chambers with no lane-to-lane influences that are claimed to provide the greatest degree of firing repeatability and capability for cell efficiency optimisation.
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).
