Abstract:
A method includes forming a release layer over a donor substrate. A plurality of devices made of a first semiconductor material are formed over the release layer. A first dielectric layer is formed over the plurality of devices such that all exposed surfaces of the plurality of devices are covered by the first dielectric layer. The plurality of devices are chemically attached to a receiving device made of a second semiconductor material different than the first semiconductor material, the receiving device having a receiving substrate attached to a surface of the receiving device opposite the plurality of devices. The release layer is etched to release the donor substrate from the plurality of devices. A second dielectric layer is applied over the plurality of devices and the receiving device to mechanically attach the plurality of devices to the receiving device.
Abstract:
Photovoltaic cells and photovoltaic modules, as well as methods of making and using such photovoltaic cells and photovoltaic modules, are disclosed. More particularly, embodiments of the photovoltaic cells selectively reflect visible light to provide the photovoltaic cells with a colorized appearance. Photovoltaic modules combining colorized photovoltaic cells may be used to harvest solar energy while providing a customized appearance, e.g., an image or pattern.

Abstract:
A photovoltaic (PV) system composed of sub-arrays, each having a group of PV cells that are electrically connected to each other, A power management circuit for each sub-array has a communications interlace and serves to connect or disconnect the sub-array to a programmable power grid. The power grid has bus rows and bus columns. A bus management circuit is positioned at a respective junction of a bus column and a bus row and is programmabie through its communication interface to connect or disconnect a power path in the grid. As a result, selected sub-arrays are connected by selected power paths to be in parallel so as to produce a low system voltage, and, alternately in series so as to produce a high system voltage that is greater than the low voltage by at least a factor often.
Abstract:
Described herein are various technologies pertaining to provision of energy to a rechargeable battery of a mobile electronic device. The mobile electronic device has an array of photovoltaic cells embedded therein or affixed thereto. The array of photovoltaic cells is electrically connected to the rechargeable battery of the mobile electronic device. A charging pad includes an array of optical emitters, which are configured to emit light when the mobile electronic device rests on or adjacent to the charging pad. A remotely situated light source acts as a luminaire and emits a directed beam of light towards the mobile electronic device to provide energy to the rechargeable battery.
