Investigation of single-wall carbon nanotube (SWNT)-polymer solar cells has been conducted towards developing alternative lightweight, flexible devices for space power applications. Photovoltaic devices were constructed with regioregular poly(3-octylthiophene)-(P3OT) and purified, >95% w/w, laser-generated SWNTs. The P3OT composites were deposited on ITO-coated polyethylene terapthalate (PET) and I-V characterization was performed under simulated AMO illumination. Fabricated devices for the 1.0% w/w SWNT-P3OT composites showed a photoresponse with an open-circuit voltage Voc of 0.98 V and a short-circuit current density (Isc) of 0.12 mA/cm2. Future optimization of carrier transport and exciton dissociation within these novel photovoltaic systems is proposed to derive from incorporation of nanostructure-SWNT complexes into the polymer.
