ABSTRACT: The objective of this STTR proposal is to develop and demonstrate a radiation hardened organic-based solar array adaptable to nanosatellites which exhibits flexibility, variable topology, high specific power, and low cost. Organic photovoltaics (OPVs) represent a transformative technology with great potential for extremely high-throughput manufacturing at very low cost. They have the potential to serve as lightweight, flexible, conformal, and low-cost solid-state power sources for space applications. Prof. Alex Jen at the University of Washington will team up with Soluxra, LLC to develop a large-area flexible OPV module that is suitable for nanosatellite application with adequate radiation hardness and power/weight efficiency. There are three specific objectives in this program: 1) Develop novel interface materials and device structures to reduce interfacial charge recombination loss in order to circumvent the radiation-induced interfacial degradation in OPVs; 2) Develop a large-area fabrication process for ITO-free, flexible OPV module with over 7.5% module efficiency and demonstrate superior mechanical flexibility that is required for integrating with the nanosatellite system; 3) Design a deployment scheme for the OPV-based integrated nanostallite system taking into account of different parameters such as stow volume, module weight, and power/weight efficiency. BENEFIT: Soluxra is a technology innovation company that develops tailored functional materials and new device platforms for large-scale photonic integration and energy-related electronic applications to improve their performance and energy efficiency. The company designs and supplies leading edge and application-tailored electronic and photonic materials to the semiconductor, telecommunications, and clean energy industries. Soluxra's OPV technology is on track to serve as lightweight, flexible, conformal, and low-cost solid-state power sources for various types of applications. In addition to developing novel geometries, we expect to reduce solar electricity cost to a level that is competitive with the current fossil fuel based energy. The ultimate cost of electricity generated by organic photovoltaic technology is dependent on three critical parameters: 1) efficiency; 2) production cost and; 3) lifetime. The success achieved in this proposal will help advance all three parameters, which will strengthen Soluxra's patent-protected organic photovoltaic technology and give Soluxra a strong competitive edge over current technology. The availability of light-weight, flexible, low-cost and deployable solar cells will significantly benefit not only the space and military applications, but also the commercial sector, providing portable power for use in a wide variety of situations.
