Özet

We investigated blends of poly hexylthiophene (P3HT) with copper indium diselenide nanocrystals for photovoltaic applications. Depending on the synthesis, the particles were shielded by different organic surfactants. Different concentrations of these nanoparticles were suspended in the polymer solutions and spin cast onto ITO glass. Morphological studies have been performed by atomic force microscopy and transmission electron microscopy. Films consisting of tri-n-octylphosphine oxide-capped CISe:P3HT show photovoltaic response. The best performance we obtained is an open-circuit voltage of about 1 V and a photocurrent of 0.3 mA/cm(2) using a white light illumination intensity of 80 mW/cm(2).
