| 20120115312 | THIN FILMS FOR PHOTOVOLTAIC CELLS - In one aspect, a method for forming CIGSSe-based thin films includes depositing at least two layers of particles on a substrate. At least one layer includes a CIGSSe particle having a chemical composition denoted by Cu(InI-xGax)(S1-ySey)2 where 0≦x ≦1 and 0≦y≦1. The particle layers are annealed individually or in combination to form a CIGSSe thin film having a composition profile along the depth of the film In addition, one or more of the particle layers may be also deposited on a pre-existing absorber and annealed to form a film having a composition profile along the depth of the film After depositing thin film precursor layers containing CIGSSe nanoparticles (and/or any other particles) on a suitable substrate in accordance with a desired concentration profile, a subsequent treatment under an Se and/or S containing atmosphere at elevated temperature may be used to convert the precursor layers into a CIGSSe absorber film In a further aspect, a method for forming multinary metal chalcogenide semiconductor layers directly on a substrate from a solution of precursors, includes depositing a plurality of metal chalcogenide particles onto a substrate to form a precursor film A species containing a metal, chalcogen, or combination thereof is dissolved in a solution containing one or more solvents to form a liquid chalcogen medium. The precursor film is contacted with the liquid chalcogen medium at a temperature of at least 50 C to form a multinary metal chalcogenide thin film | 05-10-2012 |
| 20120122268 | SELENIZATION OF PRECURSOR LAYER CONTAINING CULNS2 NANOPARTICLES - A method of fabrication of thin films for photovoltaic or electronic applications is provided. The method includes fabricating a nanocrystal precursor layer and selenizing the nanocrystal precursor layer in a selenium containing atmosphere.

| 20120138866 | SYNTHESIS OF MULTINARY CHALCOGENIDE NANOPARTICLES COMPRISING Cu, Zn, Sn, S, AND Se - Nanoparticle compositions and methods for synthesizing multinary chalcogenide CZTSSe nanoparticles containing Cu, Zn, and Sn in combination with S, Se or both are described. The nanoparticles may be incorporated into one or more ink solutions alone or in combination with other chalcogenide-based particles to make thin films useful for photovoltaic applications, including thin films from multilayer particle films having a composition profile. The composition and stoichiometry of the thin films may be further modified by subjecting the particle films to gas or liquid phase chalcogen exchange reactions. | 06-07-2012 |
| 20150119612 | Multicomponent Dividing Wall Columns - For an n-component mixture (n≧3), an array of new distillation columns is disclosed with vertical partitions that allow independent control of the vapor flowrates in each partitioned zone, while operating the columns to produce constituent product streams. Specifically, all such more operable columns with vertical partitions for ternary and quaternary feed mixtures are illustrated. For a ternary feed, through extensive computation, the minimum heat duty for each of the new columns is same as for the FTC configuration. The new columns with vertical partitions become even more attractive when the vapor split between column sections must be controlled within a narrow range. Finally, it is disclosed how a new column with vertical partition(s) drawn for an n-component mixture can be adapted to distil feed mixtures that contain more than n-components. | 04-30-2015 |
| 20150137039 | Homogeneous Mixtures for Nanoparticle Synthesis - Presented herein is a method for obtaining a dissolved selenium liquid mixture from solid selenium. The method involves mixing an amine solvent and a thiol solvent with the solid selenium to produce a liquid intermediate solution and removing a sulfur containing compound from the liquid intermediate solution to produce a dissolved selenium liquid mixture. A method for obtaining dissolved sulfur liquid mixture by mixing an amine with a thiol to produce a liquid solution that dissolves sulfur to produce a dissolved sulfur liquid mixture is also presented. In addition, a method for obtaining a dissolved sulfur and selenium liquid mixture from solid selenium and solid sulfur by mixing an amine solvent with a thiol solvent is presented. | 05-21-2015 |
