Abstract
Official abstract text for this publication.
Dopant ink compositions and methods of fabricating solar cells there from are described. A dopant ink composition may include a cross-linkable matrix precursor, a bound dopant species, and a solvent. A method of fabricating a solar cell may include delivering a dopant ink composition to a region above a substrate. The dopant ink composition includes a cross-linkable matrix precursor, a bound dopant species, and a solvent. The method also includes baking the dopant ink composition to remove a substantial portion of the solvent of the dopant ink composition, curing the baked dopant ink composition to cross-link a substantial portion of the cross-linkable matrix precursor of the dopant ink composition, and driving dopants from the cured dopant ink composition toward the substrate.
First claim
Opening claim text (preview).
What is claimed is: 1. A dopant ink composition, comprising: a solvent; a cross-linkable matrix precursor comprising siloxane monomers dispersed in the solvent, one or more of the siloxane monomers bound to a dopant species through a chemical bond; and silicon nanoparticles or silicon oxide nanoparticles. 2. The dopant ink composition of claim 1 , wherein the dopant species is an n-type dopant precursor. 3. The dopant ink composition…
