  • Publication number: 20240186435
    Abstract: A photodiode includes a substrate, a device structure, a barrier ring region, a photosensitive region, an oxide ring, and an oxide layer. The substrate has a first surface and a second surface opposite to the first surface. The device structure includes an N-type doped region, a non-doped intrinsic layer, and a P-type doped region. The barrier ring region is disposed in the substrate at a periphery of an upper portion of the substrate and is spaced apart from the P-type doped region. The photosensitive region is located above the P-type doped region. The oxide ring is disposed on the substrate and surrounds the photosensitive region. The oxide layer is disposed between the oxide ring and the second surface. The P-type doped region includes a deep doped region and a shallow doped region that are adjacent to each other. A method for manufacturing the photodiode is also provided.

  • Publication number: 20230215963
    Abstract: A solar cell device includes a supporting substrate, and an epitaxial active structure that is disposed on the supporting substrate. The epitaxial active structure has a bottom surface adjacent to the supporting substrate and a top surface opposite to the bottom surface, and is formed with an isolation section that extends from the top surface to the bottom surface. A method for producing the solar cell device is also disclosed.
