Abstract: 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.

Abstract: A method of manufacturing a microelectromechanical device includes forming at least two conductive layers on a substrate. An isolation layer is formed between the two conductive layers. The conductive layers are electrically coupled together and then the isolation layer is removed to form a gap between the conductive layers. The electrical coupling of the layers mitigates or eliminates the effects of electrostatic charge build up on the device during the removal process.

Abstract: A light guide device includes a light guide body and two or more pluralities of spaced-apart slits. The slits are formed by undercuts in the light guide body. Sidewalls of the slits form facets that redirect light impinging on the facets. In some embodiments, the light guide body is attached to a light source. The light source emits light that is injected into the light guide body and the slits redirect the light out of the light guide body and towards a desired target. 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.

Abstract: A microelectromechanical system (MEMS) device includes a first electrode, a second electrode electrically insulated from the first electrode, and a third electrode electrically insulated from the first electrode and the second electrode. The MEMS device also includes a support structure which separates the first electrode from the second electrode and a reflective element located and movable between a first position and a second position. The reflective element is in contact with a portion of the device when in the first position and is not in contact with the portion of the device when in the second position. An adhesive force is generated between the reflective element and the portion when the reflective element is in the first position. Voltages applied to the first electrode, the second electrode, and the third electrode at least partially reduce or counteract the adhesive force.

Abstract: Embodiments of an exemplary MEMS interferometric modulator comprise a movable layer and a fixed layer separated by an air gap. A driving scheme employs row/column actuation protocols which maintain voltages to the MEMS interferometric modulator that are above or below the voltage range necessary to place the MEMS interferometric modulator within a “hysteresis window” or “stability window.” Stable operation of the MEMS interferometric modulator is achieved by selecting mechanical design features that optimize the actuation and release times of the interferometric modulator. Some of the features affecting the release and actuation times include altering post spacing, altering internal stress or tension of the movable layer, altering the thickness or composition of the movable layer, altering the bulkiness of the tethers, perforating the movable layer and providing vias in the fixed layer.
