NASA Research Area of Interest: Identification, development, and validation of exploration systems and technologies
Key, central objectives of the proposal:
a. Fabrication of nanostructured photovoltaic devices made from ZnO and decorated with nanoparticles. We believe that with the nanoengineering, we can increase the efficiency to as high as 4-6% while maintaining the low cost per watt for these systems.
b. Further development and characterization of nanobattery systems tuned for photovoltaic interfacing. We have already made substantial increases in battery performance. Our metrics for this work include batteries that have charge/discharge rates as high as 200 C with capacities that are able to exceed theoretical values. Nanostructuring will allow us to reach these values.
c. Computational modeling of the proposed system to maximize energy production, storage and system durability.
d. Integration of the PV and nanobatteries into a highly efficient light-harvesting system.
