Abstract
Firefly, in collaboration with Rochester Institute of Technology, proposes an STTR program for the development of a wide-bandgap GaP-based space solar cell capable of efficient operation at temperatures above 300oC. Efficiency enhancement will be achieved by the introduction of InGaP quantum wells within the active region of the wide-gap base material. The introduction of these nanoscale features will enable harvesting of low-energy photons that are normally lost by transmission through the wide bandgap material. Successful completion of the proposed work will combine the high-temperature, radiation-tolerant wide-bandgap material with current-enhancing nanostructures to produce a high efficiency space solar cell capable of operating at higher temperatures suitable for near-sun missions. This achievement can result in significant cost savings as active cooling of PV systems would be unnecessary with this technology.
