Abstract: High performance photovoltaic devices are provided. Certain embodiments relate to the use of Boron-Nitride (BN) thin films as anti-reflection coating (ARC) material on Si and GaAs solar cells. A low and wide reflectance window covering a large energy range of the solar spectrum is available. For a large part of the useful solar spectrum, the index of refraction of the grown BN thin films remains constant at about 2.8. In another embodiment, a BN ARC is applied directly on ordinary window glass providing the device's mechanical strength.

Abstract: A method for storing energy in a capacitor includes connecting a first conductor to a first electrode and a second conductor to a second electrode. The second electrode is separated from the first electrode by a dielectric layer. The dielectric layer includes a layer of boron oxynitride, BON. The conductivity of the dielectric layer is lower than the conductivity of the first electrode or the second electrode. A voltage of at least 5 volts is applied between the first electrode and the second electrode by means of the first and second conductors.
