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 AM0 illumination. Fabricated devices for the 1.0% w/w SWNT–P3OT composites showed a photoresponse with an open‐circuit voltage V oc of 0.98 V and a short‐circuit current density (I sc ) of 0.12 mA/cm 2 . 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.
