SCHMID has launched a cost-effective process for the texturing of diamond-wire cut multi-c-Si wafers that can be easily integrated into existing production lines. DW PreTex is being made available in two versions: as a separate single unit that roughens the surface of the wafers and then uses the available texture capacity, or as a combined line for complete texturing. Based on an in-line wet process, the process is suitable for both wafer and cell manufacturers.
Fraunhofer ISE has developed a new software tool that determines the cell-to-module (CTM) effects that occur when solar cells are integrated into a module. The SmartCalc.CTM software enables manufacturers of PV modules and materials to optimize the assembly and material combination in a PV module before fabricating a prototype.
MBJ Solutions has introduced a new integrated ‘backend’ module testing system to provide greater production line operability for PV manufacturers. The MBJ backend solution combines the most important inspection tasks in one compact system: an A+A+A LED sun simulator, a hipot and grounding test and our proven EL inspection technology. All the inspection steps are performed sunny side down, which makes the integration into a production much easier than before.
Meco Equipment Engineers, a subsidiary of BE Semiconductor Industries provides its Cell Plating Line (CPL) for a wide variety of next-generation solar cell architectures migrating from silver to copper contacts, which drastically reduces the high metallization costs associated with Interdigitated Back Contact (IBC) and heterojunction cells.
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.
