    Abstract: Improved building-integrated photovoltaic systems according to certain example embodiments may include concentrated photovoltaic skylights or other windows having a cylindrical lens array. The skylight may include an insulated glass unit, which may improve the Solar Heat Gain Coefficient (SHGC). The photovoltaic skylight and lens arrays may be used in combination with strip solar cells. Arrangements that involve lateral displacement tracking systems, or static systems (e.g., that are fixed at one, two, or more predefined positions) are contemplated herein. Such techniques may advantageously help to reduce cost per watt related, in part, to the potentially reduced amount of semiconductor material to be used for such example embodiments. A photovoltaic skylight may permit diffuse daylight to pass through into an interior of a building so as to provide lighting inside the building, while the strip solar cells absorb the direct sunlight and convert it to electricity, providing for SHGC tuning.

  • Patent number: 8629423
    Abstract: In the present invention, one or more inventive designs and techniques allow formation of high speed complementary metal oxide semiconductor (CMOS) process compatible tunneling devices that are formed on low dielectric loss sheet-substrates (such as silicon or germanium for infrared or quartz and sapphire for visible or near infrared) having the first and the second smooth planar surfaces and an intermediate surface in the form of a hole, or slit, or a side edge, which extends between and connects the first and second surfaces, so that deposited from opposite sides of the sheet-substrate the first metal layer followed by its oxidation or nanometer thickness tunneling dielectric coating and the second metal layer have an overlapped coupled area within the intermediate surface, thus forming a non-planar metal-insulator-metal (MIM) tunneling junction of low capacitance and high cut-off frequency, which is capable to operate at room temperature at terahertz, infrared, and even optical frequencies.
