Abstract: A system for converting and attaching material strips to a substrate includes a dispenser configured to advance an 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.

Abstract: An automated photovoltaic (PV) subassembly manufacturing method involves in-line cutting of material strips. A tape is cut longitudinally into multiple strips. The strips are separated and guided into spaced apart positions relative to a surface of the PV cell subassembly comprising one or more PV cells. The multiple strips remain attached to the tape while the strips are guided to the spaced apart positions. The multiple strips are positioned at attachment locations on the surface of a PV cell subassembly.

Abstract: A light redirecting film defining a longitudinal axis, and including a base layer, an ordered arrangement of a plurality of microstructures, and a reflective layer. The microstructures project from the base layer, and each extends across the base layer to define a corresponding primary axis. The primary axis of at least one of the microstructures is oblique with respect to the longitudinal axis. The reflective layer is disposed over the microstructures opposite the base layer. When employed, for example, to cover portions of a PV module tabbing ribbon, or areas free of PV cells, the films of the present disclosure uniquely reflect incident light.

Abstract: The present invention provides a solar cell module, which comprises: a back panel, a rear package layer, a plurality of mutually spaced solar cells, a front package layer, and a light-transmissive element, which are successively disposed along a thickness direction of the solar cell module. The solar cell module further comprises at least one light redirecting film, each light redirecting film comprising an optical structure layer. The light redirecting film is disposed on a surface, opposite to the side where the solar cells are located, of the rear package layer; the position of the light redirecting film corresponds to a region between the solar cells. The optical structure layer faces the rear package layer, such that the optical structure layer reflects the light towards an interface between the light-transmissive element and the air; and the light is then totally internally reflected to light-facing surfaces of the solar cells.
