Investigation of Radiation Resistant Polymer Photodetectors for Space Applications
Abstract
Polymeric materials will play apivitol role in advancing next-generation ultra-miniature high bandwidth cost effective photonic optoelectronic and electrooptic systems for space applications. Polymer photodetectors (PPDs) may play a pivitol role for rapid development of robust efficient and radiation resistant space sensor systems. Several photovoltaic detector types composed of Ruthenium Complex and of poly (pohenylene vinylene)-sulfonated polystyrene were fabricated using electrostatic self-assembly processing. ThePPDs were characterized and studied for their resistance to gamma-ray-ionizing radiation. A comparison of the pre- and post- irradiation responses of the two classes of PPDs resulted in ionization-induced changes to quantum efficiencies response times material conductivities output photovoltages short circuit currents and short circuit voltages. The data and results of the preliminary investigation strongly indicated that the use of molecular self- assembly processing can be used to develop space-radiation resistant PPDs with improved quantum efficiencies at near-IR wavelengths.
