Problems solved by technology

More generally, there are no competitively priced BCs on the market, and none that would enable the industrial assembly of back contact cells with high quality standards and high throughput in a convenient and profitable manner in terms of processing time and cost. Systems with Conductive Backplanes
[0022] Fourth, it has also been found that the practice of applying an insulating dielectric mask directly on the metal conductive layer of the BC by screen printing in the known art is a limitation in building panels with a conductive backplane

Embodiment Construction

[0037] The present invention describes a composite station and method for centralizing and optimizing the production cycle of conductive backsheets with integrated encapsulation and dielectric layers, intended for assembling back-contact photovoltaic panels. More specifically, there is provided a station (10) of complex type, which is automated and integrates a plurality of operations performed in cycle sequence for the purpose of simultaneous manufacturing, which has high repeatability and low cost, provides There is a specific type of conductive backplane (300) with integrated encapsulation and dielectric layers, which is commonly referred to as BCBS, see table of prior art (Fig. 1a); Intended for use in the construction of photovoltaic panels (330) with a back contact structure, see table of prior art (Fig. 1b). It was found that the conductive backplane is of the type described in ITTV2012A000211 (Baccini et al.) and in turn comprises a semi-finished element called stack (...

Abstract

The invention provides a composite operating station and a method of drilling and fixing (10) for the continuous production of conductive backsheets (300) with an integrated encapsulating and dielectric layer, for photovoltaic panels of the back- contact type. Said 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 (100) which by rotating lays out the film of integrated encapsulating and dielectric material, (308), heats it and presses it on the conductive layer (302) of the supporting backsheet for the purpose of the fixing in a correct position, said roller being provided with openings (101) to enable drilling from outside with a laser device (120) and also to enable the forced suction from inside of the fumes and of the residues by means of an exhaust fan (130).

Description

[0001] The present invention relates to a combined perforating and fixing station and method for the continuous production of conductive backsheets with integrated encapsulation and dielectric layers for photovoltaic panels made with back-contact crystalline silicon cells. technical field [0002] The invention finds particular application in the industrial sector producing photovoltaic panels, in particular modern photovoltaic panels with back-contact crystalline silicon cells, which are also called second-generation photovoltaic panels, to distinguish them from cells with front-contact and back-contact cells separate from the regular panels. Said panels with back contact cells have on the back a multilayer support part which also integrates the electrical contacts and is commonly referred to as a conductive backsheet. The invention allows to produce in an advantageous manner a specific type of conductive backplane with integrated encapsulation and dielectric layer. [0003]...
