Flexible Photovoltaics Based on Organic Matrix Nano-Composites

Triton Systems, Inc. and Clemson University propose to develop a flexible polymeric photovoltaic assembly using a highly efficient innovative photovoltaic polymer coupled with flexible polymeric support and protective layers that can withstand the spaceenvironment. The Phase I program will verify recent data from Clemson showing that a new polymer combination has the capability to meet power generation to weight ratio of 200 W/kg at space-based illumination levels, together with a power efficiency ofmore than 10% at terrestrial illumination levels. To meet durability requirements for spacecraft applications, Triton will show in Phase I that it's novel polymer coatings and films can protect the photovoltaic layer from the environment, including atomicoxygen, ultraviolet radiation, and other space-based operational conditions. The Triton and Clemson teams will successfully complete the development work using direct experience in novel space-based flexible polymers and the photovoltaic materials. Theflexible polymeric photovoltaic system will allow folding and compact storage, along with greatly reduced weight, not possible with current inorganic photovoltaic systems. Flexible polymeric photovoltaic systems will provide space and weight benefits,along with the attendant cost savings, to future power generation equipment for satellites and space missions. Flexible photovoltaic power systems will find many terrestrial applications including mobile field operations for military service, and domesticand recreational power supplies for commercial applications.
