Multiband Solar Concentrator using Transmissive Dichroic Beamsplitting

Significant efficiency increases in photovoltaic power conversion are due to improved absorption over the broad spectrum of the sun. Semiconductors have an efficiency peak at a specific wavelength associated with the material band gap. The current trend towards high-efficiency photovoltaics involves multi-junction cells where several semiconductors are grown on top of one another creating a lay...

22.2: Photoaligned Transmissive Bistable TN-LCD

Decorative power generating panels creating angle insensitive transmissive colors

We present ultra-thin (6 to 31 nm) undoped amorphous silicon/organic hybrid solar cell structure, which can transmit desired color of light. The transmitted colors show great angular tolerance due to the negligible optical phase associated with light propagating in ultra-thin amorphous silicon (a-Si) layers. We achieved the power conversion efficiency of the hybrid cells up to 2 %; and demonstr...

Multilayered Social Networks

A social network (SN) 1 is defined as a tuple , where: V – is a not-empty set of actors representing social entities: humans, organizations, departments etc., called also vertices, nodes, vertexes, members, cases, agents, instances or points; E – is a set of directed edges (relations between actors called also arcs, connections, or ties) where a single edge is represented by a tuple ,...

Transmissive quasi-optical Ronchi phase grating for terahertz frequencies.

A transmissive, square-wave Ronchi phase grating has been fabricated from the dielectric polytetrafluoroethylene to diffract an ~0.7 THz beam quasi-optically. When illuminated by a coherent, cw terahertz (THz) source, the spot separation of the ±1 diffractive orders and the diffraction efficiency were measured as a function of THz frequency and rotation angle. The grating performance depends se...
