Embodiments of the present invention are in the field of materials, apparatus, process, methods, and designs for manufacture of a thin film energy storage devices with a capacity greater then 1 mA-hr-cmincluding thin film Lithium metal and Li+ ion batteries and capacitors having high energy density and high cycle life due to the incorporation of at least one vacuum thin film with respect to protection and electrical conductivity of the electrodes, and at least one vacuum thin film electrolyte for electrical insulation of the electrodes and ion conduction after assembly for low self discharge and high cycle life battery cells.

Energy storage device with a first metal layer formed from a precursor layer upon charge and diffused into a cathode during discharge

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.

Adiabatic planar waveguide coupler transformer

Methods of depositing materials to provide for efficient coupling of light from a first device to a second device are disclosed. In general, these methods include mounting one or more wafers on a rotating table that is continuously rotated under one or more source targets. A process gas can be provided and one or more of the source targets powered while the wafers are biased to deposit optical dielectric films on the one or more wafers. In some embodiments, a shadow mask can be laterally translated across the one or more wafers during deposition. In some embodiments, deposited films can have lateral and/or horizontal variation in index of refraction and/or lateral variation in thickness.

In accordance with the present invention, deposition of LiCoOlayers 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 LiCoOwith a desired &#x3c;101&#x3e; or &#x3c;003&#x3e; orientation. Some embodiments of the deposition address the need for high rate deposition of LiCoOfilms, 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 (&#x3e;700&#xb0; C.) anneal step that is conventionally needed to crystallize the LiCoOlayer.
