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.

Embodiments relate to an enhanced method for installing solar roofs by primarily reducing the installation time. The design is for a roofing shingle with an embedded solar module that installs intuitively like normal roofing shingles without special tools, fasteners or alignment. The shingle structure is molded out of low thermal expansion plastic composite and is compatible with commercial photovoltaic modules as well as solar infrared radiation absorbing devices.
