Abstract
This invention includes processes for making a photovoltaic absorber layer having a predetermined stoichiometry on a substrate by depositing a precursor having the predetermined stoichiometry onto the substrate and converting the deposited precursor into a photovoltaic absorber material. This invention further includes processes for making a photovoltaic absorber layer having a predetermined stoichiometry on a substrate by (a) providing a polymeric precursor having the predetermined stoichiometry; (b) providing a substrate; (c) depositing the precursor onto the substrate; and (d) heating the substrate.
