Abstract: There is disclosed ultrahigh-efficiency single- and multi-junction thin-film solar cells. This disclosure is also directed to a substrate-damage-free epitaxial lift-off (“ELO”) process that employs adhesive-free, reliable and lightweight cold-weld bonding to a substrate, such as bonding to plastic or metal foils shaped into compound parabolic metal foil concentrators. By combining low-cost solar cell production and ultrahigh-efficiency of solar intensity-concentrated thin-film solar cells on foil substrates shaped into an integrated collector, as described herein, both lower cost of the module as well as significant cost reductions in the infrastructure is achieved.

Abstract: A bipolar solar cell includes a backside junction formed by a silicon substrate and a first doped layer of a first dopant type on the backside of the solar cell. A second doped layer of a second dopant type makes an electrical connection to the substrate from the front side of the solar cell. A first metal contact of a first electrical polarity electrically connects to the first doped layer on the backside of the solar cell, and a second metal contact of a second electrical polarity electrically connects to the second doped layer on the front side of the solar cell. An external electrical circuit may be electrically connected to the first and second metal contacts to be powered by the solar cell.

Abstract: Disclosed are imprinting ink compositions for use in imprinting techniques such as SCIL. The imprinting ink compositions comprise TMO nanoparticles stabilized by selected polymerization inhibitors that allow for the formation of a stable imprinting ink composition in which polymerization of the TMO nanoparticles is effectively suppressed and from which high refractive index patterned layers can be formed. Imprinting methods using such imprinting ink compositions, optical devices including patterned layers formed from such imprinting ink compositions and lighting devices, optical sensors and photovoltaic devices including such optical elements are also disclosed.

Abstract: A system and method are provided for forming electromagnetic energy transmissive layers, which are particularly configured to selectively scatter specific and selectable wavelengths of electromagnetic energy, while allowing remaining wavelengths to pass therethrough. Processes are provided by which to form, or otherwise incorporate, one or more energy scattering layers, including uniquely implementing optical light scattering techniques in such energy scattering layers, and to objects, object portions, wall plates, lenses, filters, screens and the like that are formed of, or that otherwise incorporate, such transmissive energy-scattering layers. Refractive indices of particles fixed in a matrix are tunable in order that the finished layers provide an opaque appearance when viewed from an energy-incident excited by light in the visible spectrum. A color, pattern, texture or image of the scattering layer may be rendered according to an individual user's desires, the layers being substantially-transparent to light passing through layers.

Abstract: A wireless optical power transmission system comprising a transmitter and receiver, the transmitter comprising a laser emitting a beam, a scanning mirror for steering the beam towards said receiver and a control unit receiving signals from a detection unit on the receiver and controlling the beam power and the scanning mirror. The receiver has a photovoltaic cell having a bandgap energy of 0.75-1.2 e V, with a plurality of conductors on abeam receiving surface. A cover layer of material blocking illumination of wavelengths outside that of the laser, is disposed on the photovoltaic cell. The cover layer may have anti-reflective coatings on its top and bottom surfaces. The detection unit thus generates a signal representing the power of the laser beam impinging upon the receiver, independent of illuminations other than that of said laser beam. The control unit thus can maintain the laser power impinging on the receiver.
