Patent number: 8841549Abstract: An organic spintronic photovoltaic device (100) having an organic electron active layer (102) functionally associated with a pair of electrodes (104, 106). The organic electron active layer (102) can include a spin active molecular radical distributed in the active layer (102) which increases spin-lattice relaxation rates within the active layer (102). The increased spin lattice relaxation rate can also influence the efficiency of OLED and charge mobility in FET devices.Type: GrantFiled: September 28, 2009Date of Patent: September 23, 2014Assignee: University of Utah Research FoundationInventors: Zee valentine Vardeny, Alex Ndobe

Patent number: 8841550Abstract: A photoelectric element provided with an electron transport layer having excellent electron transport property and sufficiently wide reaction interface, and that has excellent conversion efficiency. The photoelectric element has an electron transport layer 3 and a hole transport layer 4 sandwiched between a pair of electrodes 2 and 5. The electron transport layer 3 is formed of an organic compound having a redox moiety capable of being oxidized and reduced repeatedly. The organic compound contains an electrolyte solution which stabilizes the reduced state of the redox moiety, and forms a gel layer 6 containing a sensitizing dye.Type: GrantFiled: June 16, 2010Date of Patent: September 23, 2014Assignees: Panasonic Corporation, Waseda UniversityInventors: Takashi Sekiguchi, Mitsuo Yaguchi, Takeyuki Yamaki, Hiroyuki Nishide, Kenichi Oyaizu, Fumiaki Kato, Michio Suzuka, Satoko Kambe

Publication number: 20140261692Abstract: Photoactive compositions of matter, methods for their design and synthesis, and various applications of such compositions of matter are disclosed. Such photoactive compositions may, for example, include any one or more of the following: a core moiety; a primary electron donor moiety; an electron-withdrawing moiety; and an alkyl tail. Some photoactive compositions may further include multiple additional electron donor moieties, electron-withdrawing moieties, and alkyl tails. Applications of such photoactive compositions of matter may include use in photovoltaic cells (e.g., as a p- or n-type material of the active layer of some photovoltaic cells, or as a dye to be employed in other photovoltaic cells); batteries, field-effect transistors; and light-emitting diodes.Type: ApplicationFiled: April 24, 2013Publication date: September 18, 2014Inventors: Michael D.

Patent number: 8835973Abstract: Light-emitting elements in which an increase of driving voltage can be suppressed are provided. Light-emitting devices whose power consumption is reduced by including such light-emitting elements are also provided. In a light-emitting element having an EL layer between an anode and a cathode, a first layer in which carriers can be produced is formed between the cathode and the EL layer and in contact with the cathode, a second layer which transfers electrons produced in the first layer is formed in contact with the first layer, and a third layer which injects the electrons received from the second layer into the EL layer is formed in contact with the second layer.Type: GrantFiled: March 8, 2012Date of Patent: September 16, 2014Assignee: Semiconductor Energy Laboratory Co., Ltd.Inventors: Hiromi Nowatari, Satoshi Seo, Nobuharu Ohsawa, Tetsuo Tsutsui
