Abstract:

Methods for manufacturing a cadmium telluride based thin film photovoltaic device are generally disclosed. A resistive transparent layer can be sputtered on a transparent conductive oxide layer from a metal alloy target in a sputtering atmosphere of argon and oxygen that includes argon from about 5% to about 40%. A cadmium sulfide layer can then be formed on the resistive transparent layer. A cadmium telluride layer can be formed on the cadmium sulfide layer; and a back contact layer can be formed on the cadmium telluride layer. The sputtering can be accomplished within a sputtering chamber.

US Classification:

20419212, 20419225, 20419226, 20429809, 20429812

Abstract:

A sputtering cathode is generally provided. The sputtering cathode can include a semiconducting target (e. g. , a cadmium sulfide target, a cadmium tin oxide target, etc. ) defining a sputtering surface and a back surface opposite to the sputtering surface. A backing plate can be positioned facing the back surface of the target and non-bonded to the back surface of the target. A non-bonding attachment mechanism can removably hold the target within the sputtering cathode such that the back surface is facing the backing plate during sputtering.

International Classification:

C23C 14/34

US Classification:

20419221

Abstract:

Methods for depositing a resistive transparent buffer thin film layer on a substrate are provided. The methods can include cold sputtering a resistive transparent buffer layer on a substrate (e.g., at a sputtering temperature of about 10 C. to about 100 C.) in a sputtering atmosphere comprising about 0.01% to about 5% by volume water vapor (e.g., about 0.05% to about 1% by volume water vapor). The resistive transparent buffer layer can then be annealed at an anneal temperature of about 450 C. to about 700 C. The methods of depositing a resistive transparent buffer thin film layer on a substrate can be used in a method of manufacturing a cadmium thin film photovoltaic device by forming cadmium sulfide layer on the resistive transparent buffer layer, and forming a cadmium telluride layer on the cadmium sulfide layer.

International Classification:

G02B 27/01
G06F 3/01
G06T 17/20
G06T 19/00

Abstract:

In one implementation, a method includes: obtaining locality data characterizing objects and relative spatial information of a volumetric region around a user; synthesizing a mesh map of the volumetric region based on the locality data; selecting synthesized reality (SR) content based on the mesh map, wherein the SR content satisfies a dimensional variance threshold relative to one or more portions of the mesh map; compositing at least a portion of the SR content with the mesh map in order to generate composite SR content; and presenting the composite SR content to the user in order to occlude at least a portion of a visual presentation of the volumetric region. In some implementations, the SR content is adapted to fit the one or more portions of the mesh map. In some implementations, the SR content is updated as the user location changes or the user interacts with the SR content.

International Classification:

G06T 19/00
G06F 3/0481
G06T 7/70

Abstract:

A computer system displays a representation of a camera field of view and receives one or more inputs corresponding to a request to display the representation of the field of view based on a physical object at a first pose, a virtual object at a simulated second pose, and the one or more cameras at a third pose in a physical environment. In response, if a first portion of the virtual object corresponds to physical space that is occluded by the physical object, the system: displays the representation of the physical object; forgoes displaying the first portion of the virtual object; and, if a second portion of the virtual object corresponds to physical space that is not occluded, displays the second portion, including visually deemphasizing a displayed first region of the second portion relative to a displayed second region of the second portion of the virtual object.
