    Abstract: A PV panel uses an array of small silicon sphere diodes (10-300 microns in diameter) connected in parallel. The spheres are embedded in an uncured aluminum-containing layer, and the aluminum-containing layer is heated to anneal the aluminum-containing layer as well as p-dope the bottom surface of the spheres. A phosphorus-containing layer is deposited over the spheres to dope the top surface n-type, forming a pn junction. The phosphorus layer is then removed. A conductor is deposited to contact the top surface. Alternatively, the spheres are deposited with a p-type core and an n-type outer shell. After deposition, the top surface is etched to expose the core. A first conductor layer contacts the bottom surface, and a second conductor layer contacts the exposed core. A liquid lens material is deposited over the rounded top surface of the spheres and cured to provide conformal lenses designed to increase the PV panel efficiency.

  • Patent number: 9006563
    Abstract: A interconnected arrangement of photovoltaic cells is readily and efficiently achieved by using a unique interconnecting strap. The strap comprises electrically conductive fingers which contact the top light incident surface of a first cell and extend to an interconnect region of the strap. The interconnect region may include through holes which allow electrical communication between top and bottom surfaces of the interconnect region. In one embodiment, the electrically conductive surface of the fingers is in electrical communication with an electrically conductive surface formed on the opposite side of the strap through the through holes of the interconnect region. The interconnection strap may comprise a laminating film to facilitate manufacture and assembly of the interconnected arrangement.

  • Publication number: 20150068599
    Abstract: A metallic-dielectric photonic crystal is formed with a periodic structure defining a plurality of resonant cavities to selectively absorb incident radiation. A metal layer is deposited on the inner surfaces of the resonant cavities and a dielectric material fills inside the resonant cavities. This photonic crystal can be used to selectively absorb broadband solar radiation and then reemit absorbed radiation in a wavelength band that matches the absorption band of a photovoltaic cell. The photonic crystal can be fabricated by patterning a sacrificial layer with a plurality of holes, into which is deposited a supporting material. Removing the rest of the sacrificial layer creates a supporting structure, on which a layer of metal is deposited to define resonant cavities. A dielectric material then fills the cavities to form the photonic crystal.
