|20130095579||METHOD AND APPARATUS FOR THE FORMATION OF SOLAR CELLS WITH SELECTIVE EMITTERS - Methods and apparatus for forming solar cells with selective emitters are provided. A method includes positioning a substrate on a substrate receiving surface. The substrate has a surface comprising a first patterned heavily doped region having a first dopant concentration that defines the selective emitters, and a second doped emitter region having a second dopant concentration that is less than the first dopant concentration, wherein the second doped emitter region surrounds the first patterned heavily doped region. The method further comprises determining a position of the first patterned heavily doped region by using a Fourier transform to process a filtered optical image, aligning one or more distinctive elements in a screen printing mask with the first patterned heavily doped region by using information received from the determined position of the first patterned heavily doped region, and depositing a layer of material on a portion of the first patterned heavily doped region.||04-18-2013|

|20130021054||METHOD AND APPARATUS FOR TESTING PHOTOVOLTAIC DEVICES - The present invention generally relates to an apparatus used for simulating spectrum of solar radiation and testing a photovoltaic device using the simulated spectrum of solar radiation. In one embodiment, the apparatus includes a light-source device configured to reproducing spectrum of solar radiation, the light-source device comprising a radiation plate divided into a plurality of cells, and each of the cells comprises a plurality of light-emitting diodes emitting at least two different wavelengths, and a substrate support disposed opposite to the light-source device. In one example, the plurality of light-emitting diodes emit a wavelength that is selected from the group consisting of colors blue, green, yellow, red, a first and a second color in infrared having different wavelengths with respect to each other.||01-24-2013|
|20120301602||METHOD FOR THE PRODUCTION AND CONTROL OF PLATES FOR ELECTRONICS AND RELATED APPARATUS - A method for the production and control of plates for electronics comprising a first step in which a plate is positioned, by positioning means, in a loading station; a second step in which the plate is disposed in a deposition station associated with a unit for depositing metal or other material; a third step in which the plate is disposed in an exit station and a detection means is activated to detect the presence of defects in the plate; and a fourth step in which the plate is discharged from the exit station. In the first step, the detection means is activated to identify defects in the plate disposed in the loading station. In the second step, the deposition unit is activated in order to deposit the metal on the plate when in the first step the detection means has not detected any defect in the plate.||11-29-2012|
|20120244702||METHOD FOR PRINTING A SUBSTRATE - Embodiments of the present invention generally relate to methods of printing MWT solar cells. The methods include positioning the non-light-receiving side of a solar cell substrate on a support. The solar cell substrate has a plurality of holes formed therethrough. The plurality of holes are then metalized. Metalizing the holes includes applying a first silver-containing paste within the holes, or depositing the first silver-containing paste on the interior surface of the holes. The first silver-containing paste is in electrical communication with the front surface and the back surface of the substrate. Then, a plurality of collection fingers are formed on the front surface of the substrate using a second silver-containing paste. The substrate may then be flipped, and one or more printing processes may be performed on the non-light-receiving side of the substrate.||09-27-2012|
|20120100666||PHOTOLUMINESCENCE IMAGE FOR ALIGNMENT OF SELECTIVE-EMITTER DIFFUSIONS - Embodiments of the invention generally provide a solar cell formation process that includes the formation of metal contacts over heavily doped regions that are formed in a desired pattern on a surface of a substrate. Embodiments of the invention also provide an inspection system and supporting hardware that is used to reliably position a similarly shaped, or patterned, metal contact structure on the patterned heavily doped regions to allow an Ohmic contact to be made. The metal contact structure, such as fingers and busbars, are formed on the heavily doped regions so that a high quality electrical connection can be formed between these two regions.||04-26-2012|
