Single-wall Carbon Nanotube-Polymer Solar Cells

摘要

Investigation of single-watt 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-octylthiopheme)-(P30T) and purified, >95 percent w/w, laser-generated SWNTs. The P3OT composites were deposited on ITO-coated polyethylene terapthalate (PET) and I-V characterization was performed under simulated AMD illumination. Fabricated devices for the 1 -0 percent w/w SWNT-P3OT composites showed a photore-spomse with an open-circuit voltage V_(oc) of 0-98 Vand a short-circuit current density (Isc) of Q-12mA/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.
