Polymer Based Photovoltaic for Space Applications Primary Sponsor: Department of Defense Deadline: 4/11/2001 KEYWORDS TECHNOLOGY AREAS: Materials / Processes OBJECTIVE: This STTR topic will seek to research flexible Polymer Based Photovoltaics that will provide lightweight power generation for Air Force space and terrestrial applications. DESCRIPTION: Lightweight power generation is required for both advanced space systems and terrestial mobile airbase units for the United States Air Force. Polymer-based photovoltaics offer the potential for light-weight power generation from conformable films. The lightweight feature will be critically important in decreasing the cost of transport and deployment. The flexible feature will be important for efficient stowing prior to deployment as well as for efficient surface area utilization in advanced space concepts such as microsatellites and/or Tech Sat 21 and terrestrial shelters (i.e. mobile hangars and tents). Future durability and reliability in the harsh space and operational environment is an important parameter to consider for these applications. The goal of this research is to achieve flexible photovoltaic structures with an electrical power generation to weight ratio of over 200 Wop/kg at AM0 illumination (space applications) or a power efficiency of over 10% at AM1.5 illumination (terrestrial applications) by utilizing innovative broad spectrum capture concepts and/or improved quantum efficiency light conversion approaches. PHASE I: Propose and demonstrate innovative material design approaches and concepts for generating efficienct polymer based photovoltaic cells on flexible substrates that would provide a substantial improvement in power generating capability on per weight basis. PHASE II: Develop the proposed material technology and conduct appropriate testings to validate the appropriateness of the proposed material approaches and/or concepts to provide lightweight polymer based photovoltaic cells on flexible substrate for space power applications. PHASE III DUAL USE APPLICATIONS: Lightweight flexible photovoltaic for terrestial applications. REFERENCES: 1. Polymer/Organic Based PV M.
