    摘要: Methods and devices are provided for forming thin-films from solid group IIIA-based particles. In one embodiment, a process for forming solid particles is provided. The method includes providing a first suspension of solid and/or liquid particles containing at least one group IIIA element. A material may be added to substantially increase the melting point of at least one set of group IIIA-containing particles in the suspension into higher-melting solid particles comprising an alloy of the group IIIA element and at least a part of the added material. The suspension may be deposited onto a substrate to form a precursor layer on the substrate and the precursor layer is reacted in a suitable atmosphere to form a film.

    摘要: Methods and devices are provided for forming thin-films from solid group IIIA-based particles. In one embodiment, a method is provided for bandgap grading in a thin-film device using such particles. The method may be comprised of providing a bandgap grading material comprising of an alloy having: a) a IIIA material and b) a group IA-based material, wherein the alloy has a higher melting temperature than a melting temperature of the IIIA material in elemental form. A precursor material may be deposited on a substrate to form a precursor layer. The precursor material comprising group IB, IIIA, and/or VIA based particles. The bandgap grading material of the alloy may be deposited after depositing the precursor material. The alloy in the grading material may react after the precursor layer has begun to sinter and thus maintains a higher concentration of IIIA material in a portion of the compound film that forms above a portion that sinters first.

    摘要: Methods and devices are provided for high-throughput printing of semiconductor precursor layer from microflake particles. In one embodiment, the method comprises of transforming non-planar or planar precursor materials in an appropriate vehicle under the appropriate conditions to create dispersions of planar particles with stoichiometric ratios of elements equal to that of the feedstock or precursor materials, even after settling. In particular, planar particles disperse more easily, form much denser coatings (or form coatings with more interparticle contact area), and anneal into fused, dense films at a lower temperature and/or time than their counterparts made from spherical nanoparticles. These planar particles may be microflakes that have a high aspect ratio. The resulting dense film formed from microflakes are particularly useful in forming photovoltaic devices. In one embodiment, at least one set of the particles in the ink may be inter-metallic flake particles (microflake or nanoflake) containing at least one group IB-IIIA inter-metallic alloy phase.
