摘要:
Compositions for solution-based deposition of CIGS films are described. The compositions include ternary, quaternary or quinary chalcogenide nanoparticles (i.e., CIGS nanoparticles) and one or more inorganic salts dissolved or dispersed in a solvent to form an ink. The ink can be deposited on a substrate by conventional coating techniques and then annealed to form a crystalline layer. Further processing can be employed to fabricate a PV device. The inorganic salts are included to (i) tune the stoichiometry of the CIGS precursor ink to a desirable ratio, thus tuning the semiconductor band gap, to (ii) dope the CIGS layer with additives, such as Sb and/or Na, to promote grain growth, and/or to (iii) modify and improve the coating properties of the CIGS precursor ink.
摘要:
A process for depositing a metal on a substrate involves the use of two reduction reactions in a bottom-up based tandem manner starting from a substrate surface and working upward. A first reduction reaction starts on the substrate surface at ambient temperature, and a second reduction reaction, which is initiated by the reaction heat of the first reduction reaction, occurs in a reactive ink solution film coated on top, which becomes solid after the reaction. Gas and other small molecules generated from the reduction reactions, and the solvent, can readily escape through the upper surface of the film before the solid metal layer is formed or during post-treatment, with no or few voids left in the metal film. Thus, the process can be used to form highly conductive films and features at ambient temperature on various substrates.
