  • Patent number: 11796474
    Abstract: The present invention relates to a test sample receiving block and a microbial detection apparatus using the same. The test sample receiving block may include a sample receiving block having a sample groove portion formed therein, the sample groove portion containing the sample so that a light emission module emits light to the sample and a sensor module can detect a speckle generated when the emitted light is scattered by motion of bacteria or microbes contained in the sample, wherein the sample receiving block is surface-treated to increase an optical path of light reaching the sensor module when the emitted light is reflected or scattered by the sample accommodated in the sample groove portion, so that a pattern is formed on a surface of the sample groove portion.

  • Patent number: 11757049
    Abstract: A bifacial solar cell module includes solar cells that are protected by front side packaging components and backside packaging components. The front side packaging components include a transparent top cover on a front portion of the solar cell module. The backside packaging components have a transparent portion that allows light coming from a back portion of the solar cell module to reach the solar cells, and a reflective portion that reflects light coming from the front portion of the solar cell module. The transparent and reflective portions may be integrated with a backsheet, e.g., by printing colored pigments on the backsheet. The reflective portion may also be on a reflective component that is separate from the backsheet. In that case, the reflective component may be placed over a clear backsheet before or after packaging.

  • Publication number: 20230070805
    Abstract: Approaches for the foil-based metallization of solar cells and the resulting solar cells are described. For example, a method of fabricating a solar cell involves forming a plurality of alternating N-type and P-type semiconductor regions in or above a substrate. The method also involves forming a paste between adjacent ones of the alternating N-type and P-type semiconductor regions. The method also involves curing the paste to form non-conductive material regions in alignment with locations between the alternating N-type and P-type semiconductor regions. The method also involves adhering a metal foil to the alternating N-type and P-type semiconductor regions. The method also involves laser ablating through the metal foil in alignment with the locations between the alternating N-type and P-type semiconductor regions to isolate regions of remaining metal foil in alignment with the alternating N-type and P-type semiconductor regions.
