  • Publication number: 20230361230
    Abstract: The present inventive concept relates to a thin film type solar cell including a plurality of unit cells serially connected to one another on a substrate; and a light transmission part provided in the plurality of unit cells, wherein the light transmission part is provided in a discontinuous rectilinear structure including at least one disconnection part. According to the present inventive concept, since the light transmission part is discontinuously formed, the repetition characteristic of the light transmission part including a plurality of dot patterns may be reduced, thereby effectively solving a problem where a wave pattern such as a moire phenomenon occurs when light is passing through the light transmission part.

  • Publication number: 20230235455
    Abstract: The present disclosure relates to an apparatus for processing a substrate, and more particularly, to an apparatus for processing a substrate, which deposits a thin-film on a substrate. The apparatus for processing a substrate in accordance with an exemplary embodiment includes a plurality of source gas supply units configured to respectively supply a plurality of source gases among which at least one contains (3-Dimethylaminopropyl)Dimethylindium (DADI), a gas mixing unit connected to each of the plurality of source gas supply units and having an inner space in which each of the plurality of source gases moves at a passing speed less than a supply speed of each of the plurality of source gases, and a chamber connected with the gas mixing unit and having a reaction space to which the source gases mixed in the inner space are supplied.
