摘要： Provided are a backlight unit and a display device having the same. The backlight unit includes a light source configured to generate light and a plurality of light guide members stacked so that individual surfaces of each light guide member contact a surface of another one of the light guide members, the plurality of light guide members configured to guide the light. Each of the light guide members includes a light incident for receiving incident light from the light source, an opposite surface facing an adjacent one of the light guide members, and a plurality of light path change patterns disposed on the opposite surface.

摘要： Laser foil trim approaches for foil-based metallization of solar cells, and the resulting solar cells, are described. For example, a method of fabricating a solar cell includes attaching a metal foil sheet to a surface of a wafer to provide a unified pairing of the metal foil sheet and the wafer, wherein the wafer has a perimeter and the metal foil sheet has a portion overhanging the perimeter. The method also includes laser scribing the metal foil sheet along the perimeter of the wafer using a laser beam that overlaps the metal foil sheet outside of the perimeter of the wafer and at the same time overlaps a portion of the unified pairing of the metal foil sheet and the wafer inside the perimeter of the wafer to remove the portion of the metal foil sheet overhanging the perimeter and to provide a metal foil piece coupled to the surface of the wafer.

摘要： A method for fabricating a solar cell is disclosed. The method can include forming a dielectric region on a surface of a solar cell structure and forming a first metal layer on the dielectric region. The method can also include forming a second metal layer on the first metal layer and locally heating a particular region of the second metal layer, where heating includes forming a metal bond between the first and second metal layer and forming a contact between the first metal layer and the solar cell structure. The method can include forming an adhesive layer on the first metal layer and forming a second metal layer on the adhesive layer, where the adhesive layer mechanically couples the second metal layer to the first metal layer and allows for an electrical connection between the second metal layer to the first metal layer.

摘要： Methods of fabricating solar cell emitter regions using silicon nano-particles and the resulting solar cells are described. In an example, a method of fabricating an emitter region of a solar cell includes forming a region of doped silicon nano-particles above a dielectric layer disposed above a surface of a substrate of the solar cell. A layer of silicon is formed on the region of doped silicon nano-particles. At least a portion of the layer of silicon is mixed with at least a portion of the region of doped silicon nano-particles to form a doped polycrystalline silicon layer disposed on the dielectric layer.

摘要： A solar cell can include a silicon layer formed over a silicon substrate. The silicon layer can have a P-type doped region and an N-type doped region. Portions of the silicon layer can have a grain size larger than other portions of the silicon layer. For example, larger grains of the silicon layer formed within a depletion region between P-type and N-type doped regions can minimize recombination loss at the P-type and N-type doped region boundaries and improve solar cell efficiency.
