摘要: A system is provided that integrates an autonomous energy harvesting capacity in buildings in an aesthetically neutral manner. A unique set of structural features combine to implement a hidden energy harvesting system on a surface of the building to provide electrical power to the building, and/or to electrically-powered devices in the building. 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.

摘要: Provided is an adduct represented by Formula 1: A.PbY2.Q (1) wherein A is an organic or inorganic halide, Y is F−, Cl−, Br− or I− as a halogen ion, and Q is a Lewis base including a functional group containing a nitrogen (N), oxygen (O) or sulfur (S) atom with an unshared pair of electrons as an electron pair donor. The Lewis base is maintained more stable in the lead halide adduct. Therefore, the use of the adduct enables the fabrication of a perovskite solar cell with high conversion efficiency.

摘要: A holographic antenna integrated with photovoltaic cells and method for use of the same are described. In one embodiment, the method for using an antenna comprises receiving position data indicative of an antenna aperture of an antenna after the antenna has been placed in a position to increase capture of solar energy by one or more photovoltaic (PV) structures integrated into a surface of the antenna aperture; and in response to the position data, electronically steering an array of antenna elements of the antenna to redirect a beam toward a satellite based on the position of the antenna while maintaining the position of the antenna for increased capture of the solar energy.

摘要: A method of manufacturing a thin-film solar cell includes forming a first electrode on a substrate; forming a first petition groove for dividing the first electrode; forming a semiconductor layer on the first electrode and in the first partition groove; forming a second partition groove for dividing the semiconductor layer; forming a second electrode on the semiconductor layer and in the second partition groove; and forming a third partition groove for dividing the second electrode and the semiconductor layer. At least one of the steps of forming the first partition groove, the second partition groove, and the third partition groove includes forming an opening in a partition groove forming layer to expose a lower layer surface below the partition groove forming layer, bringing a needle into contact with the lower layer surface, and forming the partition groove by moving the needle in a predetermined direction.
