Patent number: 11404594Abstract: A positive-intrinsic-negative (PIN) photosensitive device is provided. A p-type semiconductor layer composed of molybdenum oxide and having valence band energy between valence band energy of an intrinsic semiconductor layer and an upper electrode is used to replace a p-type semiconductor layer used in a conventional PIN photodiode, so that the PIN photodiode may be prepared without using borane gas. More, a difference between valence band energy of the p-type semiconductor layer and the intrinsic semiconductor layer is used to transport holes located in a valence band, so that it is unnecessary to use an active layer of a thin film transistor, so that the PIN photosensitive device may be stacked on the thin film transistor to reduce aperture ratio loss of a display panel.Type: GrantFiled: June 24, 2020Date of Patent: August 2, 2022Assignee: Wuhan China Star Optoelectronies Technology Co., Ltd.Inventors: Jianfeng Yuan, Fei Ai, Jiyue Song
