Heraeus Photovoltaics has launched a new PERC (Passivated Emitter Rear Contact) metallization paste. The SOL9631 front-side paste has a new and unique glass chemistry combined with a new organic vehicle system. Due to a denser microstructure it is tailored for ultra-fine line printability for screen printing.
PV Nano Cell has commercially developed ‘Sicrys’, a single-crystal, nanometric silver conductive ink delivering enhanced performance for digital conductive printing in mass production applications. The inks are also available in copper-based form, delivering all of the product’s properties and advantages with improved cost efficiency.
SENTECH Instruments has designed the SENperc PV for the measurement of Al2O3/SiNx layer stacks and single films for the passivation of PERC (Passivated Emitter Rear Cell) solar cells. The stability of the deposition process is monitored over the long-term thereby the maintenance intervals of the deposition tools can be optimized.
INDEOtec’s Octopus II PECVD system has proven capabilities in the formation of heterojunction solar cells that enables top and bottom side thin film substrate deposition without the need of substrate flipping and vacuum breakage. The proprietary reactor design and a unique electrode arrangement allow low plasma ignition levels and low ion bombardments, which result in superior film thickness uniformity and excellent passivation levels.
DuPont Photovoltaic Solutions developed and launched a new advanced ‘DuPont’ ‘Solamet’ PV19B photovoltaic metallization front side paste that has a highly conductive silver composition and part of the PV19x family of pastes, with innovative material science which enables finer line design and excellent printability.
LayTec has introduced the first commercially available system for simulation and monitoring of LID (Light Induced Degredation). ‘LID Scope’ is a table-top system that helps to quantify the expected performance loss of any solar cell directly at the production line or in the lab. The tool performs accelerated or real-life degradation tests fully automatically. It is claimed to deliver highly reproducible results and a permanent monitoring of Voc changes by integrated metrology.
Shanghai HIUV New Materials Co has introduced a newly developed ‘pre-crosslinking’ EVA. The G401W EVA, part of a new G Series range is designed specifically for double glass PV modules with the aim of eliminating a series of issues encountered with conventional EVA materials in the lamination process.
SiTec, a subsidiary of centrotherm photovoltaics said it was developing a highly efficient technology called ‘Genesis’ that when perfected would reduce monosilane fluid-bed reactor (FBR) polysilicon production capital and operating costs by approximately 45% each, compared to legacy FBR decomposition processes.
PV Nano Cell announced its plans to enter the US solar market with its ‘Sicrys’ silver and copper inks. The inks are expected to accelerate the adoption of solar photovoltaics (PV) by reducing the cost of silicon solar cell production, using an efficient process that produces sustainable inks without the use of hazardous wastes, and by increasing solar cell efficiencies at a mass production scale.
centrotherm is launching the ‘c.REG’ conveyor belt furnace for monocrystalline p-type solar cell regeneration, which is claimed to achieve a reduction in light induced degradation (LID) from 6% to 1%, within less than a one minute processing cycle time. The company is showcasing the regeneration technology at SNEC 2015, being held in Shanghai, China.
