Abstract: A method is provided that integrates an autonomous energy harvesting capacity in vehicles in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the vehicle to provide electrical power to the vehicle, and/or to electrically-powered devices in the vehicle. Color-matched, image-matched and/or texture-matched optical layers are formed over energy harvesting components, including photovoltaic energy collecting components. Optical layers are tuned to scatter selectable wavelengths of electromagnetic energy back in an incident direction while allowing remaining wavelengths of electromagnetic energy to pass through the layers to the energy collecting components below. The layers uniquely implement optical light scattering techniques to make the layers appear opaque when observed from a light incident side, while allowing at least 50%, and as much as 80+%, of the energy impinging on the energy or incident side to pass through the layer.

Abstract: Lateral and vertical microstructure enhanced photodetectors and avalanche photodetectors are monolithically integrated with CMOS/BiCMOS ASICs and can also be integrated with laser devices using fluidic assembly techniques. Photodetectors can be configured in a vertical PIN arrangement or lateral metal-semiconductor-metal arrangement where electrodes are in an inter-digitated pattern. Microstructures, such as holes and protrusions, can improve quantum efficiency in silicon, germanium and III-V materials and can also reduce avalanche voltages for avalanche photodiodes. Applications include optical communications within and between datacenters, telecommunications, LIDAR, and free space data communication.

Abstract: A photovoltaic cell includes a junction, formed from an n-type semiconductor material and a p-type semiconductor material, a trench, opening toward the light-incident side of the junction, for trapping reflected light, and two photon conversion layers. A first photon conversion layer, arranged at the light-incident side of the junction, converts photons from a higher energy to a lower energy suitable for absorption by the semiconductor material, and a second photon conversion layer, arranged at the opposite side of the junction, converts photons from a lower energy to a higher energy suitable for absorption by the semiconductor material.

Abstract: A p− type semiconductor substrate 20 has a first principal surface 20a and a second principal surface 20b opposed to each other and includes a photosensitive region 21. The photosensitive region 21 is composed of an n+ type impurity region 23, a p+ type impurity region 25, and a region to be depleted with application of a bias voltage in the p− type semiconductor substrate 20. An irregular asperity 10 is formed in the second principal surface 20b of the p− type semiconductor substrate 20. An accumulation layer 37 is formed on the second principal surface 20b side of the p− type semiconductor substrate 20 and a region in the accumulation layer 37 opposed to the photosensitive region 21 is optically exposed.

Abstract: Devices, systems and techniques are described for producing and implementing articles and materials having nano-scale and microscale structures that exhibit superhydrophobic, superoleophobic or omniphobic surface properties and other enhanced properties. In one aspect, a surface nanostructure can be formed by adding a silicon-containing buffer layer such as silicon, silicon oxide or silicon nitride layer, followed by metal film deposition and heating to convert the metal film into balled-up, discrete islands to form an etch mask. The buffer layer can be etched using the etch mask to create an array of pillar structures underneath the etch mask, in which the pillar structures have a shape that includes cylinders, negatively tapered rods, or cones and are vertically aligned. In another aspect, a method of fabricating microscale or nanoscale polymer or metal structures on a substrate is made by photolithography and/or nano imprinting lithography.

Abstract: An energy conversion device comprises at least two thin film photovoltaic cells fabricated separately and joined by wafer bonding. The cells are arranged in a hierarchical stack of decreasing order of their energy bandgap from top to bottom. Each of the thin film cells has a thickness in the range from about 0.5 μm to about 10 μm. The photovoltaic cell stack is mounted upon a thick substrate composed of a material selected from silicon, glass, quartz, silica, alumina, ceramic, metal, graphite, and plastic. Each of the interfaces between the cells comprises a structure selected from a tunnel junction, a heterojunction, a transparent conducting oxide, and an alloying metal grid; and the top surface and/or the lower surface of the energy conversion device may contain light-trapping means.
