Methods for producing complex films, and films produced thereby

摘要

A method for producing a film, the method comprising melting a layer of precursor particles on a substrate until at least a portion of the melted particles are planarized and merged to produce the film. The invention is also directed to a method for producing a photovoltaic film, the method comprising depositing particles having a photovoltaic or other property onto a substrate, and affixing the particles to the substrate, wherein the particles may or may not be subsequently melted. Also described herein are films produced by these methods, methods for producing a patterned film on a substrate, and methods for producing a multilayer structure.

1. A method for producing a film, the method comprising:
(i) producing precursor particles from microbes, wherein said precursor particles have a size of up to 100 microns and a composition comprising at least one element selected from S, Se, and Te and at least two elements selected from Cu, Fe, Zn, Sn, Cd, In, Ga, and Al; (ii) disposing said precursor particles on a substrate to form a layer of said precursor particles on said substrate; and (iii) melting said layer of precursor particles on said substrate until at least a portion of the melted particles are planarized and merged in said film.
