Flexible, Lightweight, Low-Cost Organic Photovoltaics with Improved Efficiency, Phase I

Completed Technology Project

Project Description

Flexible, Lightweight, Low-Cost Organic Photovoltaics with Improved Efficiency, Phase I
Both manned and unmanned off-Earth missions of the future will require very lightweight, high efficiency, flexible and durable photovoltaic (PV) arrays to generate electric power. Current PV technology horizons do not meet the requirements for expanded mission capability. Although inorganic PVs hold the record for solar power conversion efficiency, they are inflexible, heavy, and expensive to produce. There is increasing interest in a new type of PV technology that is based on organic semiconducting materials. Much of this research has been limited by the availability of stable n-type organic semiconductors. TDA Research, Inc. proposes to use a new class of n-type conjugated polymers to produce more efficient organic PV devices. Two of our new n-type materials are available through Sigma-Aldrich, and the current technology readiness level (TRL) stands at 3 with proof-of-concept results and commercial sales. At the end of this Phase I project we will have produced prototype organic PVs in the laboratory (TRL 4) and a successful Phase II project would lead to several commercial n-type organic semiconductor products being used in the full scale production of lightweight flexible PVs (TRL 6).
