  • Publication number: 20180331349
    Abstract: In accordance with the present invention, deposition of LiCoO2 layers in a pulsed-dc physical vapor deposition process is presented. Such a deposition can provide a low-temperature, high deposition rate deposition of a crystalline layer of LiCoO2 with a desired <101> or <003> orientation. Some embodiments of the deposition address the need for high rate deposition of LiCoO2 films, which can be utilized as the cathode layer in a solid state rechargeable Li battery, Embodiments of the process according to the present invention can eliminate the high temperature (>700° C.) anneal step that is conventionally needed to crystallize the LiCoO2 layer.

  • Patent number: 10120130
    Abstract: A solar cell includes a waveguide core for receiving light, a first layer formed on the waveguide core, a second layer formed on the first layer, a third layer formed on the second layer, first metalization coupled to the first layer, and second metalization coupled to the third layer. The first layer comprises a first optical film which varies in an index of refraction in a lateral direction between a first input end where the light is received and a first output end where the light is emitted. In some embodiments, wherein one or more of the first, second, or third layers has a tapered lateral thickness. In some embodiments, the first, second, and third layers form a PIN device. In some embodiments, the waveguide core has a first index of refraction that is lower than respective indexes of refraction for the first, second, and third layers.

  • Publication number: 20140332371
    Abstract: A method of deposition of a transparent conductive film from a metallic target is presented. A method of forming a transparent conductive oxide film according to embodiments of the present invention include depositing the transparent conductive oxide film in a pulsed DC reactive ion process with substrate bias, and controlling at least one process parameter to affect at least one characteristic of the conductive oxide film. The resulting transparent oxide film, which in some embodiments can be an indium-tin oxide film, can exhibit a wide range of material properties depending on variations in process parameters. For example, varying the process parameters can result in a film with a wide range of resistive properties and surface smoothness of the film.

  • Patent number: 8173482
    Abstract: Methods for protecting a cadmium sulfide layer on a substrate are provided. The method can include sputtering a cadmium sulfide layer onto a substrate from a cadmium sulfide target at a sputtering pressure (e.g., about 10 mTorr to about 150 mTorr), and sputtering a cap layer directly on the cadmium sulfide layer. The cap layer can be sputtered directly onto the cadmium sulfide layer without breaking vacuum of the sputtering pressure. Methods are also provided for manufacturing a cadmium telluride based thin film photovoltaic device through depositing a cadmium sulfide layer on a substrate, depositing a cap layer directly on the cadmium sulfide layer, heating the substrate to sublimate at least a portion of the cap layer from the cadmium sulfide layer, and then depositing a cadmium telluride layer on the cadmium sulfide layer. An intermediate substrate for forming a cadmium telluride based thin-film photovoltaic device is also provided.
