Embodiments of the present invention generally relate to the fabrication of solar cells and more specifically to a buffer layer for improving the performance and stability of surface passivation of Si solar cells. Generally, a passivation layer stack containing a buffer layer (interlayer) is formed on a surface of the silicon-based substrate. In one embodiment, the passivation layer stack may be formed on the back surface of the substrate. In another embodiment, the passivation layer stack is formed on the back surface of the substrate and a front emitter region (light receiving surface) of the substrate.

A method for identifying a person using their finger-joint print including the outer skin around the proximal interphalangeal joint of a finger, the method comprising: capturing (10) an image of the finger-joint print of the person; extracting (12) a region of interest (ROI) based on a local convexity property of the finger-joint print; extracting (13) features representing the orientation of the lines in a finger-joint print image from the ROI using an extended Gabor phase coding scheme and the extracted features are represented in competitive code maps; wherein angular distance between the competitive code maps is compared (14) with a reference set in a database to identify the person.
摘要:
A deposition/etching/deposition process is provided for filling a gap in a surface of a substrate. A liner is formed over the substrate so that distinctive reaction products are formed when it is exposed to a chemical etchant. The detection of such reaction products thus indicates that the portion of the film deposited during the first etching has been removed to an extent that further exposure to the etchant may remove the liner and expose underlying structures. Accordingly, the etching is stopped upon detection of distinctive reaction products and the next deposition in the deposition/etching/deposition process is begun.
