A system for converting and attaching material strips to a substrate includes a dispenser configured to advance an en elongated tape having length l1 and width w1 with l1>w1 relative to a surface of a substrate. A cutting tool cuts the elongated tape transversely along the width w1 of the tape to produce a strip having length l2 and width w2. During the cutting, a portion of the cutting Stool pushes a first surface of the strip against a gripper while cutting the tape. The gripper holds the first surface of the strip against the gripper while moving to position an opposing, second surface of the strip over the surface of the substrate. The gripper releases the strip after positioning the strip.

A method is disclosed for applying an electrical conductor to a solar cell, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. The composition is, or may be made, electrically conductive. Once the membrane is loaded, the grooved first surface of the membrane is brought into contact with a front or/and back of a solar cell. A pressure is then applied between the solar cell and the membrane(s) so that the composition loaded to the grooves adheres to the solar cell. The membrane(s) and the solar cell are separated and the composition in the groove is left on the solar cell surface. The electrically conductive particles in the composition are then sintered or otherwise fused to form a pattern of electrical conductor on the solar cell, the pattern corresponding to the pattern formed in the membrane(s).

A method is disclosed for applying an electrical conductor to an electrically insulating substrate, which comprises providing a flexible membrane with a pattern of groove formed on a first surface thereof, and loading the grooves with a composition comprising conductive particles. The composition is, or may be made, electrically conductive. Once the membrane is loaded, the grooved first surface of the membrane is brought into contact with a front or/and back of the substrate. A pressure is then applied between the substrate and the membrane(s) so that the composition loaded to the grooves adheres to the substrate. The membrane(s) and the substrate are separated and the composition in the groove is left on the surface of the electrically insulating substrate. The electrically conductive particles in the composition are then sintered to form a pattern of electrical conductors on the substrate, the pattern corresponding to the pattern formed in the membrane(s).

An apparatus is disclosed for transferring a pattern of a composition containing particles of an electrically conductive material and a thermally activated adhesive from a surface of a flexible web to a surface of a substrate. The apparatus comprises: respective drive mechanisms for advancing the web and the substrate to a nip through which the web and the substrate pass at the same time and where a pressure roller acts to press the surfaces of the web and the substrate against one another, a heating station for heating at least one of the web and the substrate prior to, or during, passage through the nip, to a temperature at which the adhesive in the composition is activated, a cooling station for cooling the web after passage through the nip, and a separating device for peeling the web away from the substrate after passage through the cooling station, to leave the pattern of composition adhered to the surface of the substrate.
