Abstract:
1. A method of making a thin-film device, the method comprising: providing a substrate having a major surface area, the substrate having a first layer on a first surface area of the substrate's major surface area; depositing a second layer onto the first layer, wherein the first and second layers form part of a battery, wherein the depositing of the second layer further includes supplying an amount of ion-assist energy to the second layer to aid in crystalline layer formation while controlling a stoichiometry of the crystalline layer without substantially heating the substrate, and wherein the battery is a thin-film lithium battery; depositing one or more other layers to form a photovoltaic cell connected to the battery; attaching an integrated circuit to the substrate; and operatively coupling the integrated circuit to charge the battery using current from the photovoltaic cell, wherein either the first or the second layer forms a cathode layer of the battery, wherein the battery includes the cathode layer, an anode layer, and an electrolyte layer located between and electrically isolating the anode layer from the cathode layer.
