PRiMELiNE Turnkey Solutions by Roth & Rau After mounting of busbars and application of edge sealant the processed substrate, the washed and cleaned back glass, and the encapsulant foil are mounted together to a stacked sandwich. This fully automated process tool is called "marriage". The marriage station is designed to process glass and encapsulant foil for module sizes up to 1200 x 1600 mm; encapsulant foil material may be EVA or PVB, which is fed to the machine from rolls and then cut to the appropriate size and precisely placed onto the substrate. Encapsulant foil size and positioning with respect to the edge sealant "frame" is essential for a good subsequent lamination process result. The Laminator forms a mechanical stable module from the glassfoil-glass stack created in the process before, that can withstand all environmental effects that a PV module is exposed to. This is accomplished by applying heat and pressure to the stack for a defined time. Temperatures are adjustable and precisely controllable, depending on the encapsulant foil material. Pressure is adjusted in order to obtain a bubble-free, homogenously polymerized encapsulant material. Included in the scope of delivery is the integrated cooling press to cool down the modules to temperatures that allow safe subsequent processing. After lamination the PV module is almost ready, only the specially adapted junction box needs to be connected to the busbar on the module backside. This process step can be executed either manually or fully automatic, with crimp or soldering connection to the busbar, with adhesive pads, hot melts or silicone adhesives, with metal or polymer junction boxes: Obviously, all customer requirements can be fully met by the flexible process station design. Final testing consists of a Flasher, a Wet Leakage Tester, and a Visual Inspection Station. Flashing simulates PV module output at sunlike illumination (STC, 1000 W/m 2 , AM 1.5 global) and therefore enables determination of module output parameters Pmax, Impp, Umpp, Isc, Uoc, and - finally - the module efficiency . Design of the Flasher may be either horizontally or vertically, depending on the individual requirements at customer's site. A Wet Leakage Test (= High Potential Test) ensures proper electrical insulation of the module. UL1703 and IEC61730 are the basic standards, covering requirements for safety and construction of photovoltaic modules to address prevention of electrical shock and fire hazards. These two base standards are to be used in conjunction with IEC61646. Only modules that pass this test are considered as "sellable modules" and will be labeled according to its output power. Label printer and software connection to Flasher and Wet Leakage tester is included in the Backend Cluster design. Metrology tools utilized within the Roth & Rau CTF Solar Back-End Cluster comprise of a back glass inspection (broken corners, chipping, and edge cracks) and a module inspection (lamination bubbles, lamination inclusions, glass breakage). All inspections are fully automatic, incorporating image recognition and analysis. Optionally, additional inspection methods (electro luminescence, photo luminescence) can be integrated in the Back-End Cluster layout. Key features: Cluster output > 60 substrates / h Integrated substrate transport system Short substrate edge leading Integrated inspection and metrology (adaptable) Flexible process design (adaptable to various encapsulant foil materials Junction box designs, process/throughput requirements at lamination Flasher mechanical design), Xenon lamp flashing Automatic module labeling Flexible and adaptable MES connection Integrated cooling press at the laminator All Back-End tools are designed to comply with the Roth & Rau CTF Solar principle of delivering only environmental friendly tools, as also realized in the entire PRiMELiNE CdTe Turnkey production line, which is designed to keep the "environmental footprint" as small as possible: All fab emissions are post-treated already at tool-level so that virtually no contaminated or hazardous substances can be released to the environment, and used processing fluids are recycled for minimal consumption values.
