  • Publication number: 20130075666
    Abstract: Disclosed is a polymer electrolyte composition, a gel-type polymer electrolyte obtained by mixing the same at normal temperature, and a dye-sensitized solar cell containing the electrolyte. Since the poly(alkylene carbonate)-based polymer is included, a crosslinking process by radiation of heat or UV is not required when the polymer electrolyte is manufactured, such that a manufacturing process is simple. Accordingly, the polymer electrolyte is useful for mass production of a solar cell and maintained in a uniform state without a phase separation between two components due to excellent affinity between the polymer and the organic solvent included in the electrolyte, and has excellent electrode-electrolyte interface property in the solar cell due to an adhesive property of the gelled polymer electrolyte.

  • Publication number: 20130059410
    Abstract: An ink for forming CIGS photovoltaic cell active layers is disclosed along with methods for making the ink, methods for making the active layers and a solar cell made with the active layer. The ink contains a mixture of nanoparticles of elements of groups IB, IIIA and (optionally) VIA. The particles are in a desired particle size range of between about 1 nm and about 500 nm in diameter, where a majority of the mass of the particles comprises particles ranging in size from no more than about 40% above or below an average particle size or, if the average particle size is less than about 5 nanometers, from no more than about 2 nanometers above or below the average particle size. The use of such ink avoids the need to expose the material to an H2Se gas during the construction of a photovoltaic cell and allows more uniform melting during film annealing, more uniform intermixing of nanoparticles, and allows higher quality absorber films to be formed.

  • Publication number: 20130037755
    Abstract: Apparatus and method for plasma deposition of thin film photovoltaic materials at microwave frequencies. The apparatus avoids deposition on windows that couple microwave energy to deposition species. The apparatus includes a microwave applicator with one or more conduits that carry deposition species. The applicator transfers microwave energy to the deposition species to energize them to a reactive state. The conduits physically isolate deposition species that would react or otherwise combine to form a thin film material at the point of microwave power transfer and deliver the microwave-excited species to a deposition chamber. Supplemental material streams may be delivered to the deposition chamber without passing through the microwave applicator and may combine with deposition species exiting the conduits to form a thin film material. Precursors for the microwave-excited deposition species include fluorinated forms of silicon.

    Abstract: Organic photovoltaic (OPV) devices are disclosed. An exemplary device has first and second electrodes and an organic, photovoltaically active zone located between the first and second electrodes. The photovoltaically active zone includes an organic electron-donor material and an organic electron-acceptor material. The electron-donor material includes one or more trivalent- or tetravalent-metal phthalocyanines with alkylchalcogenide ring substituents, and is soluble in at least one organic solvent. This solubility facilitates liquid-processability of the donor material, including formation of thin-films, on an unlimited scale to form planar and bulk heterojunctions in organic OPVs. These donor materials are photovoltaically active in both visible and near-IR wavelengths of light, enabling more of the solar spectrum, for example, to be applied to producing electricity. Also disclosed are methods for producing the metalated phthalocyanines and actual devices.

  • Publication number: 20120104324
    Abstract: A precursor material for forming a film of a group IB-IIIA-chalcogenide compound and a method of making this film are disclosed. The film contains group IB-chalcogenide nanoparticles and/or group IIIA-chalcogenide nanoparticles and/or nanoglobules and/or nanodroplets and a source of extra chalcogen. Alternatively, the film may contain core-shell nanoparticles having core nanoparticles include group IB and/or IIIA elements, which are coated with a shell of elemental chalcogen material. The method of making a film of group IB-IIIA- chalcogenide compound includes mixing the nanoparticles and/or nanoglobules and/or nanodroplets to form an ink, depositing the ink on a substrate, heating to melt the extra chalcogen and to react the chalcogen with the group IB and group IIIA elements and/or chalcogenides to form a dense film.

  • Publication number: 20120089180
    Abstract: A polymerizable composition includes at least one monomer, a photoinitiator capable of initiating polymerization of the monomer when exposed to light, and a phosphor capable of producing light when exposed to radiation (typically X-rays). The material is particularly suitable for bonding components at ambient temperature in situations where the bond joint is not accessible to an external light source. An associated method includes: placing a polymerizable adhesive composition, including a photoinitiator and energy converting material, such as a down-converting phosphor, in contact with at least two components to be bonded to form an assembly; and, irradiating the assembly with radiation at a first wavelength, capable of conversion (down-conversion by the phosphor) to a second wavelength capable of activating the photoinitiator, to prepare items such as inkjet cartridges, wafer-to-wafer assemblies, semiconductors, integrated circuits, and the like.

    Abstract: Techniques for increasing conductivity of graphene films by chemical doping are provided. In one aspect, a method for increasing conductivity of a graphene film includes the following steps. The graphene film is formed from one or more graphene sheets. The graphene sheets are exposed to a solution having a one-electron oxidant configured to dope the graphene sheets to increase a conductivity thereof, thereby increasing the overall conductivity of the film. The graphene film can be formed prior to the graphene sheets being exposed to the one-electron oxidant solution. Alternatively, the graphene sheets can be exposed to the one-electron oxidant solution prior to the graphene film being formed. A method of fabricating a transparent electrode on a photovoltaic device from a graphene film is also provided.

  • Publication number: 20120040513
    Abstract: Apparatus and method for plasma deposition of thin film photovoltaic materials at microwave frequencies. The apparatus avoids unintended deposition on windows or other microwave transmission elements that couple microwave energy to deposition species. The apparatus includes a microwave applicator with one or more conduits passing therethrough that carry deposition species. The applicator transfers microwave energy to the deposition species to activate or energize them to a reactive state. The conduits physically isolate deposition species that would react or otherwise combine to form a thin film material at the point of microwave power transfer and deliver the microwave-excited species to a deposition chamber. One or more supplemental material streams may be delivered directly to the deposition chamber without passing through the microwave applicator and may combine with deposition species exiting the one or more conduits to form a thin film material.
