COMPOSITE STATION AND METHOD OF DRILLING AND FIXING FOR THE CONTINUOUS PRODUCTION OF A CONDUCTIVE BACKSHEET WITH AN INTEGRATED ENCAPSULATING AND DIELECTRIC LAYER, FOR PHOTOVOLTAIC PANELS OF THE BACK-CONTACT TYPE

摘要

Composite operating station and method of drilling and fixing for the continuous production of conductive backsheets with an integrated encapsulating and dielectric layer, for photovoltaic panels of the back-contact type. The composite operating station is automated and integrates a plurality of working processes carried out simultaneously in a cyclic sequence. In particular, it is based on a multifunction cylindrical roller which by rotating lays out the film of integrated encapsulating and dielectric material, heats it and presses it on the conductive layer of the supporting backsheet for the purpose of the fixing in a correct position, the roller being provided with openings to enable drilling from outside with a laser device and also to enable the forced suction from inside of the fumes and of the residues by means of an exhaust fan.
