    摘要: Color photovoltaic (PV) devices formed using interferometric stacks tuned to reflect color covering the front side or back side of a PV cell, device, panel, or array are disclosed. Interferometric stacks covering PV devices include interferometric modulators (IMODs), or dichroic pair stacks. Such devices can be configured to reflect enough light of select wavelengths so as to impart a color, while transmitting enough light to the PV active material so as to generate useful electricity.

The light guide panel is edge illuminated by a light source positioned behind the array display elements. The light from such a light source is coupled to a second light guide disposed behind the array of display elements and positioned laterally with respect to the light source. The light in the second light guide is coupled into the first light guide using a small optical coupling element such as a turning mirror. In some embodiments the second light guide may comprise the backplate of the display device.

    摘要: A method of modeling phase characteristics of thermodynamic systems utilizing pseudo-properties strategy and a reduced number of variables is disclosed herein. The method describes a means of determining the probability of phase splitting of mixtures of materials at a given temperature, pressure, and composition by characterizing the functions that describe the system via pseudo-properties, and also by describing the system in n−1 or fewer variables, where n represents the number of components in the system of interest. In an embodiment, a multi-component system is characterized in one variable, thereby providing simplified thermodynamic models in a time-efficient manner. In addition, the information generated by this reduced-variable calculation can further be used as a starting point for calculations of equations of state.

    摘要: Certain embodiments include interferometrically tuned photovoltaic cells wherein reflection from interfaces of layered photovoltaic devices coherently sum to produce an increased field in an active region of the photovoltaic cell where optical energy is converted into electrical energy. Such interferometrically tuned or interferometric photovoltaic devices (iPV) increase the absorption of optical energy in the active region of the interferometric photovoltaic cell and thereby increase the efficiency of the device. In various embodiments, one or more optical resonant cavities and/or optical resonant layers is included in the photovoltaic device to increase the electric field concentration and the absorption in the active region.

In some embodiments, the target is a display and a first plurality of slits directs light from the light source across the light guide body and over the face of the display. A second plurality of slits then directs light out of the light guide body and towards the display.
