Manz showcased its new equipment for wet-chemical processing of crystalline silicon solar cells at SNEC 2012 in Shanghai this May. The IPSG CEI 4800 is designed for chemical edge isolation (CEI) and phosphor silicate glass (PSG) post process removal. The tool is capable of handing 4800 wafers per hour and sold as a bundle with the Manz SpeedPicker for loading and unloading.
centrotherm photovoltaics is offering an upgrade package for its centaurus technology, which combines a selective emitter with a dielectric passivated backside. The technology implementation is said to already be combined with fine line printing, reducing paste consumption of the front side silver paste by more than 20%. The achieved conversion efficiencies on 156x156mm² monocrystalline (cz) wafers have already reached the 20% level. Currently, centrotherm said it has more than 50MW of centaurus technology being ramped into volume production.
SoLayTec has introduced its Process Development Tool for ultrafast ALD (Atomic Layer Deposition) for depositing (aluminium oxide) Al2O3. The tool is said to be capable of a highly effective surface passivation of the cell (front and rear) with a throughput of 100 wph (wafers per hour).
Vitronic’s VINSPECsolar electroluminescence inspection system is designed to detect defects within solar cells that could influence electrical performance of the solar module. By using electroluminescence inspection, all defect areas are automatically detected, displayed and classified by relevant software before lamination, so that reworking can increase the module’s efficiency. Archived electroluminescence images of the finished module also serve as proof of the delivered quality.
Stäubli Robotics has launched the TP80 fast Picker, an ultrafast four-axis new technology of high-speed pickers for standard pick & place applications, delivering speeds of more than 200 picks per minute and more flexibility at a lower cost, according to the company.
Tanaka Precious Metals has introduced what it claims is the world’s first conductive silver ink capable of forming electronic circuits using only hardening by ultraviolet (UV) light without the need for hardening by heating. A total of three silver inks using different types of resin and reaction initiator will be available and users can select the materials according to their manufacturing equipment and application.
BTU International’s ‘Tritan’ HV90 dual-lane metallization firing system features increased throughput at 3600 wafers per hour, and includes an edge belt, volatile organic compound (VOC) abatement and a single zone spike with less than 3 seconds spike time. BTU claims that by switching to the dual-lane system, cell manufacturers can expect a 35% increase in capital efficiency coupled to unparalleled performance in lane to lane matching.
centrotherm has introduced a new fast firing furnace tool, c.FIRE for metallization of front and rear contacts of solar cells. It is suited for all common sorts of metallization paste and comes with an integrated and versatile dryer. Emphasis in the design was also placed on a compact footprint and maintenance systems in order to reduce the operating costs for solar cell producers.
Isra Solar Vision has introduced a unique defect inspection system for compound spots on cell edges, which can cause short-circuits when the cells enter the flashing process. Inspection at this stage is seen to ensure level ‘A’ quality for at least the first 400 cells per batch. The new ‘SOLARSCAN-Bevel’ system is designed to prevent wafer/cell scrap and provides the possibility to react immediately with protective or maintenance actions.
Singulus Technologies had launched the ‘SINGULAR ICP-PECVD’ platform for the development and production of high efficiency silicon solar cells, requiring passivation layers for R&D and production applications. The platform has been applied at research centers and institutes in Europe, America and Asia.
