Abstract: Designs of extremely high efficiency solar cells are described. A novel alternating bias scheme enhances the photovoltaic power extraction capability above the cell band-gap by enabling the extraction of hot carriers. When applied in conventional solar cells, this alternating bias scheme has the potential of more than doubling their yielded net efficiency. When applied in conjunction with solar cells incorporating quantum wells (QWs) or quantum dots (QDs) based solar cells, the described alternating bias scheme has the potential of extending such solar cell power extraction coverage, possibly across the entire solar spectrum, thus enabling unprecedented solar power extraction efficiency. Within such cells, a novel alternating bias scheme extends the cell energy conversion capability above the cell material band-gap while the quantum confinement structures are used to extend the cell energy conversion capability below the cell band-gap.

Abstract: A video display system based on constructing images through displaying orthogonal basis function components of the image is disclosed. The system is comprised of two display components aligned and driven concurrently. The first display component is a coarse pixel array. The second display component is a spatial light modulator whose geometric details are finer than the first pixel array. The overall system reconstructs the intended video to be displayed at the finer geometric details of the second display component at a minimal image quality loss through the use of time-domain display of orthogonal image basis function components. The resultant system has a considerably reduced interconnection complexity and number of active circuit elements, and also requires a considerably smaller video data rate if a lossy image reconstruction scheme is used. An embodiment with a LED based display and an LCD based spatial light modulator utilizing the concepts, and methods to drive the displays are described herein.

Abstract: A video display system is described which is formed by an array of pixels comprised of fast responding light elements, row select and column select switches and pixel data drivers, and a computation subsystem which generates the control signals for the select lines and the video data. The overall system reconstructs the intended image or video to be displayed through successively displaying subframes of images corresponding to orthogonal image basis function components of the original image acting on a grouping of pixels selected using multiple row and column lines. The resultant system is an architecture which enables one to implement certain video decompression techniques directly on the light elements, as opposed to implementing these techniques in digital processing, and can have a considerably reduced raw video data requirement than a system in which pixels are addressed individually, and enables higher dynamic range to be achieved with similar digital-analog-converter specifications.
