Abstract: The present disclosure describes a portable solar module including a plurality of strips, each strip including at least one bus bar formed on a top surface thereof. The solar module further includes electrically conductive adhesive electrically connecting each strip when applied to the strip where the strips are arranged to overlap one another to connect the strips in series, and at least one string of overlapped strips, wherein the portable solar module has an output of less than about 130 W and less than about 30V.

Abstract: The present disclosure describes methods of forming a colored conductive ribbon for a solar module which includes combining a conductive ribbon with a channeled ribbon holder, applying a color coating to at least the conductive ribbon within the channel, curing the color coating on the conductive ribbon, and separating the conductive ribbon from the channeled holder.

Abstract: The present disclosure describes methods of forming solar modules including a shingled array of strips of solar cells and methods of bonding the strips of shingled solar cells.

Abstract: A solar cell is provided including a substrate having a front and back side, a metallization pattern deposited on the front side, the metallization pattern including a plurality of front side bus bars each including fingers extending therefrom, and a plurality of back side bus bars deposited on the back side. On the front side, one front side bus bar is formed along an edge of the front side of the substrate, and a remainder of the front side bus bars are unequally spaced across the substrate. On the back side of the substrate, only one back side bus bar is formed along an edge of the back side of the substrate, and a remainder of the back side bus bars are unequally spaced across the substrate.

Abstract: A solar module for incorporation in a motor vehicle including a front sheet having a curvature in at least two directions, at least one set of strings, wherein each string is formed of a plurality strips of a solar cell, and each of the strips is arranged in an overlapping manner with an adjacent strip, and electrically connected to an adjacent strip with an electrically conductive adhesive. The module further includes a first encapsulation layer disposed between the front sheet and a first side of the at least one set of strings, a second encapsulation layer formed on a second side of the ate least one set of strings, and a back sheet formed on the second encapsulation layer.

Abstract: The present disclosure describes a method of forming a solar sub-assembly including etching a solar cell, singulating the solar cell to form a plurality of strips, each strip including at least a bus bar, screen printing electrically conductive adhesive (ECA) onto at least one edge of the singulated strips of the solar cell, and shingling the singulated strips such that the ECA bonds one of the plurality of strips to another to form a string.

Abstract: Bifacial solar modules with enhanced power output are described herein including a first and second transparent support layer, a first and second encapsulating layer, a plurality of electrically interconnected bifacial solar cells with gaps between the interconnected bifacial solar cells, and one or more highly reflective films or coatings attached to the solar module at the gaps between the bifacial solar cells or an edge gap at a peripheral edge of the solar module beyond the bifacial solar cells, wherein the films or coatings redirect light impacting them such that the light is directed towards at least one of the bifacial solar cells.
