摘要： A vertical multi-junction photovoltaic device includes a structured substrate including a plurality of substantially vertical elongated structures protruding from a planar surface of the structured substrate. An areal density of the elongated structures at a first sliced plane parallel to the planer surface is different than an areal density of the elongated structures at a second sliced plane parallel to the planar surface. The device further includes least a first sub-cell and a second sub-cell, each having a corresponding vertical p-n or p-i-n junction formed of conformal layers, the first sub-cell being formed in a first region incorporating the first sliced plane and the second sub-cell being formed above the first sub-cell in a second region incorporating the second sliced plane.

摘要： A non-close-packed vertical junction photovoltaic device includes a substrate, a two-dimensional array of elongate nanostructures extending substantially perpendicularly from a surface of the substrate, and a thin film solar cell disposed over the nanostructures such that the thin film solar cell substantially conforms to the topography of the nanostructures. An average separation of nearest neighbor solar cell coated nanostructures is greater than zero and less than a vacuum wavelength of light corresponding to a band gap of absorption. The thin film solar cell may include an active region that conforms to the elongate nanostructures, a first electrode that conforms to a surface of the active region, and a second electrode. A separation of opposing outer surfaces of the first electrode extending along adjacent elongate nanostructures is greater than zero and less than the vacuum wavelength of the light corresponding to the band gap of the active region.

摘要： A method of fabricating a device structure, comprises: forming an insulating layer (3b) over a first set of devices disposed over a substrate (3); forming one or more vias in the insulating layer; disposing a second set of devices (6) over the insulating layer, wherein devices of the second set comprise respective electrical contacts (6a) and are disposed over the insulating layer (3b) such that a side on which a contact (6a) can be accessed faces the substrate (3); and forming one or more electrical contacts between the first set of devices and the second set of devices (6) through the via(s). The second set of devices and at least one via are positioned such that one or more of the vias lies at least partially within the footprint of two devices, each belonging to a different device layer.
