Patent number: 11177687Abstract: This disclosure describes systems, methods, and apparatus for a combined LED driver and emergency backup battery system. The LED driver can include current regulation circuitry as well as a bus enabling charging and discharging of an energy storage device from and to the bus. A master controller can control charging and discharging of the energy storage device via a controller of an energy storage management system, and also communicate with the current regulation circuitry to control a balance of power between an AC mains, the energy storage device, and driving of an LED light source. Accessories may be coupled to the bus and receive low voltage power from the bus and optionally receive commands from the master controller and provide sensed data back to the controller. A wireless network interface to the master controller can enable system states based on electrical power company indications and instructions.Type: GrantFiled: May 8, 2019Date of Patent: November 16, 2021Assignee: LEDVANCE LLCInventors: Anthony Catalano, Steven S.

Patent number: 8987115Abstract: Methods of preparing a thin crystalline silicon film for transfer and devices utilizing a transferred crystalline silicon film are disclosed. The methods include preparing a silicon growth substrate which has an interface defining substance associated with an exterior surface. The methods further include depositing an epitaxial layer of silicon on the silicon growth substrate at the surface and separating the epitaxial layer from the substrate substantially along the plane or other surface defined by the interface defining substance. The epitaxial layer may be utilized as a thin film of crystalline silicon in any type of semiconductor device which requires a crystalline silicon layer. In use, the epitaxial transfer layer may be associated with a secondary substrate.Type: GrantFiled: August 21, 2008Date of Patent: March 24, 2015Assignee: Alliance for Sustainable Energy, LLCInventors: Charles Teplin, Howard M.

Patent number: 8466447Abstract: A crystal oriented metal back contact for solar cells is disclosed herein. In one embodiment, a photovoltaic device and methods for making the photovoltaic device are disclosed. The photovoltaic device includes a metal substrate with a crystalline orientation and a heteroepitaxial crystal silicon layer having the same crystal orientation of the metal substrate. A heteroepitaxial buffer layer having the crystal orientation of the metal substrate is positioned between the substrate and the crystal silicon layer to reduce diffusion of metal from the metal foil into the crystal silicon layer and provide chemical compatibility with the heteroepitaxial crystal silicon layer. Additionally, the buffer layer includes one or more electrically conductive pathways to electrically couple the crystal silicon layer and the metal substrate.Type: GrantFiled: August 6, 2009Date of Patent: June 18, 2013Assignee: Alliance for Sustainable Energy, LLCInventors: Howard M.

Publication number: 20060208257Abstract: A crystalline, highly textured or biaxially textured, foreign (non-silicon) material, which is closely lattice-matched to silicon, is deposited on a glass or other amorphous or multi-crystalline substrate to provide a template for hetero-epitaxial growth of highly ordered crystalline silicon semiconductor layers on such substrates. This process enables crystalline silicon semiconductor devices, such as photovoltaic devices, transistors, and the like, on such inexpensive substrates, or to enable reduced temperature processing for some kinds of semiconductor devices, such as bottom gate transistors, on crystalline silicon substrates.Type: ApplicationFiled: March 15, 2005Publication date: September 21, 2006Inventors: Howard Branz, David Ginley, Charles Teplin
