  • Patent number: 8987756
    Abstract: An LED luminaire has a dye-sensitized solar cell for converting light emitted from a light source to electric energy and uses the converted electric energy. Since the dye-sensitized solar cell plays a role of a diffusion plate, the LED luminaire may diffuse light and convert wasted light into power. Further, since energy consumption and green-house gas generation decrease, it is possible to provide an environment-friendly LED luminaire. Moreover, if the power generated by the dye-sensitized solar cell is used for cooling the LED luminaire, it is possible to enhance heat dissipation efficiency of the LED luminaire.

  • Patent number: 8987863
    Abstract: Electrical components for microelectronic devices and methods for forming electrical components. One particular embodiment of such a method comprises depositing an underlying layer onto a workpiece, and forming a conductive layer on the underlying layer. The method can continue by disposing a dielectric layer on the conductive layer. The underlying layer is a material that causes the dielectric layer to have a higher dielectric constant than without the underlying layer being present under the conductive layer. For example, the underlying layer can impart a structure or another property to the film stack that causes an otherwise amorphous dielectric layer to crystallize without having to undergo a separate high temperature annealing process after disposing the dielectric layer onto the conductive layer. Several examples of this method are expected to be very useful for forming dielectric layers with high dielectric constants because they avoid using a separate high temperature annealing process.
