  • Publication number: 20240348839
    Abstract: Disclosed are a method of encoding a division block in video encoding and a method of decoding a division block in video decoding. An input picture is divided into encoding unit blocks. The encoding unit blocks are divided into sub-blocks. The sub-blocks are encoded by selectively using at least one of intra prediction encoding and inter prediction encoding. A decoding process is performed through a reverse process of the encoding method. When pixel values of an encoding unit block are encoded in video encoding, the flexibility in selecting an encoding mode is increased and the efficiency of encoding is increased.

  • Publication number: 20240290551
    Abstract: Disclosed are a transparent electrode for a solar cell and a method of manufacturing the same. The transparent electrode for a solar cell has a low Young's modulus, excellent elasticity, self-healing properties, an average visible-light transmittance sufficient to implement bifacial properties, and excellent power conversion efficiency (PCE). In addition, the method of manufacturing the transparent electrode for a solar cell does not require an additional deposition process, so the electrode-manufacturing time can be reduced, and the electrode-manufacturing process can be performed separately from other solar-cell-manufacturing processes, which is advantageous for mass production and large-area application.
