List of Equipment:
1x IMA “Wrap Around” Packing Line: it’s the end of production line. A lifting system send the PV cells boxes to the storage unit. N°10 boxes are picked from storage belt and are packed in carton box. Each box is tag with “bar code” through a labelling system and it is sent to the palletize system. A XYZ manipulator picks 24 boxes and place them on pallets. Full pallets are moved to exit position where they are handled by fork-lift.

2x Baccini Wafer Stacker: it automatically load wafers from the 100 slot cassettes into stacks for ARC deposition.
2x Baccini Screen Printer Line: L-R walking beam line with rotary printers. It consists of: ICOS wafer integrity check + automatic rejection; front printer and dryer; spare printer + dryer for MWT concept; flipper; back pad printer and dryer; Al printer and dryer; optional flipper for firing face up; printers has automatic paste dispensing systems. ICOS visual inspection system before every dryer for visual inspection; cassettes buffer after every printing stage; balance for weight check after Al printer;
2x Stangl Isotexturing Wet Bench: automatic acidic isotexturing machine for mc-Si wafers. The machine is loaded manually with wafers in 100 slot cassettes. Texturing is performed as 200 wafers / batch process with possibility to optimize time, temperature and bath composition. Cassettes are unloaded manually.
2x PSG Removal Wet Bench: the machine is loaded manually with wafers in 100 slot cassettes, the processing is done as a 200 wafers batch HF process with possibility to optimize time and bath composition.
