    摘要： An absorber layer may be formed on a substrate using atomic layer deposition reactions. An absorber layer containing elements of groups IB, IIIA and VIB may be formed by placing a substrate in a treatment chamber and performing atomic layer deposition of a group IB element and/or one or more group IIIA elements from separate sources onto a substrate to form a film. A group VIA element is then incorporated into the film and annealed to form the absorber layer. The absorber layer may be greater than about 25 nm thick. The substrate may be coiled into one or more coils in such a way that adjacent turns of the coils do not touch one another. The coiled substrate may be placed in a treatment chamber where substantially an entire surface of the one or more coiled substrates may be treated by an atomic layer deposition process. One or more group IB elements and/or one or more group IIIA elements may be deposited onto the substrate in a stoichiometrically controlled ratio by atomic layer deposition using one or more self limiting reactions.

    摘要： 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.

    摘要： Methods for passivating crystalline grains in an active layer for an optoelectronic device and optoelectronic devices having active layers with passivated crystalline grains are disclosed. Crystalline grains of an active layer material and/or window layer material are formed within the nanotubes of an insulating nanotube template. The dimensions of the nanotubes correspond to the dimensions of a crystalline grain formed by the deposition technique used to form the grains. A majority of the surface area of these grains is in contact with the wall of the nanotube template rather than with other grains.

    摘要： Methods and devices for increase power output from solar devices. In one embodiment, the technique enables the front hot solar panel surface to be cooled by attachment of a thermoelectric multilayer stack to the back solar panel surface. The thermoelectric stack cools the solar panel front surface by drawing heat from the front to the back of the panel. That heat is transformed into mechanical vibrations using an inverse Peltier effect and that mechanical energy then transformed into electrical energy using a piezoelectric effect. Power output is first increased by lower operating temperature on front, resulting in a higher power conversion efficiency for the photovoltaic effect taking place in the CIGS/CdS active layers or other thin films, then from an additional power output from secondary electrical energy created from mechanical arising from the temperature-gradient driven occurrence of the thermoelectric effect.
