  • Publication number: 20120276725
    Abstract: Methods of selectively forming a metal-doped chalcogenide material comprise exposing a chalcogenide material to a transition metal solution, and incorporating transition metal of the transition solution into the chalcogenide material without substantially incorporating the transition metal into an adjacent material. The chalcogenide material is not silver selenide. Another method comprises forming a chalcogenide material adjacent to and in contact with an insulative material, exposing the chalcogenide material and the insulative material to a transition metal solution, and diffusing transition metal of the transition metal solution into the chalcogenide material while substantially no transition metal diffuses into the insulative material.

  • Publication number: 20120276683
    Abstract: A new, more economical method for preparing titania pastes for use in more efficient dye-sensitized solar cells is disclosed. The titania pastes are prepared by mixing titania nanoparticles with a titania sol including a titanium precursor. The disclosed method enables the control of titania nanoparticle concentration and morphology in the titania paste and is economical due to the relatively low reaction temperatures. The performances of dye-sensitized solar cells prepared using the disclosed titania pastes are also disclosed.

  • Patent number: 8293142
    Abstract: A composition containing fine silver particles which have a uniform particle size, can form a fine drawing pattern, and have a small environmental impact, a method for producing that composition, a method for producing fine silver particles, and a paste having fine silver particles are provided. The fine silver particles are produced by carrying out a fluid preparation step of preparing a reduction fluid, a silver reaction step, and a filtration/washing step. The reaction step is carried out by adding an aqueous silver nitrate fluid to a reduction fluid whose temperature has been increased to a range between 40 and 80° C. The aqueous silver nitrate fluid is added at a stretch. The composition containing fine silver particles is produced by dispersing the composition containing the fine silver particles in a polar fluid.
