Automatic assembly method of a photovoltaic panel with back-contact cells of crystalline silicon, comprising the following operating phases: • horizontal positioning on a panel-holding tray of a conductive backsheet (307-308, 310, 300a) provided with a layer of encapsulating material with dielectric material and with the holes for the contacting of the cells facing upwards, which is also called BCBS; • laying of conductive material between the cell and the holes, such as an ECA conductive adhesive; • loading of the cells on said BCBS positioning them with the sensitive face facing upwards and with the contacts of both polarities in correspondence of the holes; • pre-fixing of the cells to the lower encapsulating material; • superimposition of the upper encapsulating material; • laying of the front glass; • overturning of the layered components and sending to the rolling furnace; said method, wherein said laying of conductive material occurs directly on the cell, in correspondence of the back contacts, by means of printing; said method, wherein said pre-fixing occurs by means of localised heat and in combination with said loading phase, simultaneously and in a reciprocally coordinated way; said method being characterised in that said laying of conductive material is in a macro-phase of printing on the cell with loading and pre-fixing of the printed cells, wherein one provides the simultaneous and reciprocally coordinated execution of the following operating sub-phases (11a-11f): a first sub-phase of oriented loading of the cells with the contacts upwards on a mobile cell-holding tray, a second sub-phase of silk-screen printing of conductive adhesive on said contacts obtaining printed cells, a third sub-phase of control of the laying of said conductive adhesive on each cell and optional re-positioning of the screen or stencil for an automatic correction of the following print, a fourth sub-phase of overturning of said printed cells by taking them from said cell-holding tray, a fifth sub-phase of oriented transport of the printed cells until they are positioned on the surface of said BCBS, a sixth sub-phase of pre-fixing to the underlying encapsulating material in the final position applying localized heat from above to increase the adhesion between the solar cells and the top-most layer of the BCBS; said macro-phase (11, 11a-11f) being carried out in one single combined compact and automated workstation of the multi-function type; said macro-phase (11, 11a-11f) being carried out immediately after said phase of positioning of the BCBS and immediately before said phase of superimposition of the upper encapsulating layer. • horizontal positioning on a panel-holding tray of a conductive backsheet (307-308, 310, 300a) provided with a layer of encapsulating material with dielectric material and with the holes for the contacting of the cells facing upwards, which is also called BCBS; • laying of conductive material between the cell and the holes, such as an ECA conductive adhesive; • loading of the cells on said BCBS positioning them with the sensitive face facing upwards and with the contacts of both polarities in correspondence of the holes; • pre-fixing of the cells to the lower encapsulating material; • superimposition of the upper encapsulating material; • laying of the front glass; • overturning of the layered components and sending to the rolling furnace;
