SUBSTRATE PREPARATION FOR ENHANCED THIN FILM FABRICATION FROM GROUP IV SEMICONDUCTOR NANOPARTICLES

摘要

A method for producing a thin film promoter layer is disclosed. The method includes depositing a Group IV semiconductor ink on a substrate, the Group IV semiconductor ink including a set of Group IV semiconductor nanoparticles and a set of metal nanoparticles to form a porous compact. The method also includes heating the substrate to a first temperature between about 350°C to about 765°C and for a first time period between 5 min to about 3 hours.
