    摘要： The disclosed technology relates generally to photovoltaic cells, and more particularly to photovoltaic cells with plated metal contacts. In one aspect, a method of fabricating a photovoltaic cell with a metal contact pattern on a surface of a semiconductor substrate includes locally smoothening portions of the surface of the semiconductor substrate by using a first laser, at predetermined locations. The method additionally includes doping the surface of the semiconductor substrate to form an emitter region. The method additionally includes forming a dielectric layer on the surface of the semiconductor substrate, and subsequently forming openings through the dielectric layer by using a second laser, thereby locally exposing the underlying surface of the semiconductor substrate at the predetermined locations. The method further includes forming metal contacts at exposed regions of the surface of the semiconductor substrate by plating.

    摘要： Methods of passivating light-receiving surfaces of solar cells with crystalline silicon, and the resulting solar cells, are described. In an example, a solar cell includes a silicon substrate having a light-receiving surface. An intrinsic silicon layer is disposed above the light-receiving surface of the silicon substrate. An N-type silicon layer is disposed on the intrinsic silicon layer. One or both of the intrinsic silicon layer and the N-type silicon layer is a micro- or poly-crystalline silicon layer. In another example, a solar cell includes a silicon substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the silicon substrate. An N-type micro- or poly-crystalline silicon layer disposed on the passivating dielectric layer.

    摘要： Methods of passivating light-receiving surfaces of solar cells with high energy gap (Eg) materials, and the resulting solar cells, are described. In an example, a solar cell includes a substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the substrate. A Group III-nitride material layer is disposed above the passivating dielectric layer. In another example, a solar cell includes a substrate having a light-receiving surface. A passivating dielectric layer is disposed on the light-receiving surface of the substrate. A large direct band gap material layer is disposed above the passivating dielectric layer, the large direct band gap material layer having an energy gap (Eg) of at least approximately 3.3. An anti-reflective coating (ARC) layer disposed on the large direct band gap material layer, the ARC layer comprising a material different from the large direct band gap material layer.

The support structure (11) includes at least one tank (17) for said conductive fluid, the bottom wall (19) of which is to be arranged opposite said substrate (3) during the deposition, and said bottom wall (19) has perforations for enabling the flow (18) of said conductive fluid (13) onto the substrate (3) when said fluid (13) is subjected to the radiation (15) from said light source (5), wherein the perforations are formed according to a pattern of the fluid to be deposited onto the substrate (3). The die (7) further comprises an optical plate (9) having a pattern (30) pervious to the radiation from said light source (5), the optical plate (9) being impervious to the radiation from said light source (5) outside said pattern (30), while the pattern (30) pervious to the radiation from said light source on said optical plate (9) corresponds to a pattern covering the pattern (22) of the perforations of said support structure.
