In embodiments of the present invention an undoped amorphous, nanocrystalline or microcrystalline semiconductor layer and a heavily doped amorphous, nanocrystalline, or microcrystalline semiconductor layer are formed on a monocrystalline silicon lamina. The lamina is the base region of a photovoltaic cell, while the amorphous, nanocrystalline or monocrystalline layers serve to passivate the surface of the lamina, reducing recombination at this surface. In embodiments, the heavily doped layer additionally serves as either the emitter of the cell or to provide electrical contact to the base layer. The undoped and heavily doped layers are deposited at low temperature, for example about 150 degrees C. or less with hydrogen dilution. This low temperature allows use of low-temperature materials and methods, while increased hydrogen dilution improves film quality and/or conductivity.

A hinge assembly includes a shaft, a rotary member, and a tube. The rotary member includes a friction body and is fixed to the shaft. The tube rotatably engages with the friction body of the rotary member. When the tube rotates to a predetermined position relative to the rotary member, the friction body deforms, thereby generating friction between the friction body and the tube.

A near infrared phosphorescent organometallic complex includes a cyclometalating ligand and a transition metal. The cyclometalating ligand includes a fused aromatic ring structure with carbon atoms, and a heteronuclear aromatic ring with a nitrogen atom. The transition metal is bonded to the nitrogen atom in the heteronuclear aromatic ring and one of the carbon atoms in the fused aromatic ring structure. The heteronuclear ring can be part of the fused aromatic ring. The organometallic complex is capable of phosphorescent emission with maximum emission intensity occurring at a wavelength in a range from about 650 nm to about 2000 nm.

An exemplary support stand (102) for a flat-panel display body includes an elevating support (30), a monitor bracket (50), and a support member (20). The elevating support includes a first chassis (321), a second chassis (322), a plurality of supporting blocks (3231) for connecting end portions of the first chassis and the second chassis, an elastic member (391), a first pivot subassembly (305), and a second pivot subassembly (306). The monitor bracket is rotatably connected to the first pivot subassembly. The support member is rotatably connected to the second pivot subassembly. The elastic member is capable of exerting a rebound force on two of the first chassis, the second chassis, and the supporting blocks. The first and second pivot subassemblies are fixed to the supporting blocks. The monitor bracket and the support member are rotatably connected to the first and second pivot subassembly correspondingly.
