The invention concerns a method of manufacturing a photovoltaic module comprising at least two electrically connected photovoltaic cells, each photovoltaic cell () being multi-layered structure disposed on a substrate () having down-web direction (X) and a cross-web direction (Y). The method comprises providing a plurality of spaced-apart first electrode strips () over the substrate (), each first electrode strip extending along the cross-web direction (Y), and providing, over the first electrode strips layer, at least one insulating strip () of an insulator material extending along the down-web direction (X), each insulating strip defining a connecting area and an active area. A functional stack () comprising a full web coated layer of photoactive semiconductor material is formed over the first layer and within the active area. A plurality of spaced-apart second electrode strips () are provided within the active area, each second electrode strip extending along the cross-web direction (Y), so as to form photovoltaic cells and a photovoltaic module is formed by electrically connecting at least two adjacent photovoltaic cells, by extending over the insulating strips () electrical connection patterns to electrically connect, within the connecting area(s), the second electrode strip of an photovoltaic cell to the first electrode strip of an adjacent photovoltaic cell.

Method of manufacturing printed photovoltaic modules

A method for manufacturing a photovoltaic module, comprising at least two electrically connected photovoltaic cells, the module comprising an insulating substrate covered with a layer of a first conductive material. The method comprises: a) forming a groove defining a first and second lower electrode; and b) forming, on each lower electrode, a stack comprising an upper electrode and a photo-active layer. The method further comprises, between steps a) and b), forming: a first insulating step on the groove; then a conductive strip partially covering the first insulating strip; then a second insulating strip partially covering the conductive strip.

Method for manufacturing a photovoltaic module and photovoltaic module thus obtained

The present invention relates to a method for manufacturing a photovoltaic module (), comprising the following steps: forming, on an electrically conducting material, a furrow (A) defining a first (A) and second (B) lower electrode; then forming, on each lower electrode, a stack () comprising at least one upper electrode () and an intermediate photo-active layer (), to form a first (A) and second (B) photovoltaic cell, respectively; then forming an electrical connection (A) between said cells (A,B). Before the stacks, the following are formed: a first insulating strip (A) in the furrow (A); and a second electrically insulating strip (B) on the second lower electrode, delimiting an inactive area (B) on said second electrode. The stack () next formed on the second cell is positioned outside the inactive area.
