Abstract

A novel method for the fabrication of polypyrrole nanotubes (PPyNTs) possessing quantum dots (QDs) was developed for optoelectronic devices. PbSe QDs were effectively attached to the thiolated PPyNT-SH without affecting the dispersion stability of QDs and hence ensuring their homogeneous distribution in the polymer. Transmission electron microscopic images showed a large number of PbSe QDs absorbed in PPyNT-SH. The polymer nanotube composites were also investigated for the application of photovoltaic cells. An open circuit voltage (V oc) of 0.45 V and short-circuit photocur-rent density (1 sc) of 2.4 μ A cm -2 were found in P3HT/PPyNT-PbSe polymeric solar cells. Further optimization will be provided by changing various parameters and conditions.
