As the need for carbon-free power becomes more and more important, solar energy is our best alternative. Perskiovite solar cells have the potential reach high efficiency, supplying 3X the energy that a common solar cell could. A textile-based solar cell with this high of an efficiency would have numerous impacts. From solar window films that could supply power for entire skyscrapers to washable solar powered electronic clothing that would required no battery.

Designed research project and laboratory methods
Secured grant funding for research
Tested a series of polymer precursor solutions with three different polymers: Polyurethane (PU), Polyethylene Oxide (PEO), Polyacrylate Nitrile (PAN)
Each Precursor solution was tested with two methods of seeding: a ZnO nanoparticle dispersion, a Zn Acetate/Ni Acetate with a Oxidation Step
AFM Imaging was used to examine the structure of seeding
Garment prototype was developed with an electrical system that could support solar textile system
Wrote project repots and research paper to present findings

Results:
There were significant barriers with both hydrophilic and hydrophobic Zinc precursor solutions and obtaining even dispersion in the fibers. PAN was found to be a promising fiber that was strong enough to support oxidation process for seeding but development is still a long ways from a working solar cell system.

A prototype was constructed using a simple circuitry system in a waterproof garment to display how an solar powered electrical system could be incorporated into a functional design.
