ABSTRACT
In this research we
investigated the effect of composition on the fabrication and morphological
characteristics of a hybrid polymeric solar cell which consists of an electron
donating conjugated polymer, namely is poly(3-hexylthiophene) (P3HT) combined
with an electron-accepting component, which is a type of inorganic compound of
TiO2 nanocrystals. The composition
of TiO2 in the blends is varied and
the optimum performance of the devices are studied. The optical and
morphological characterizations are carried out via UV-Visible absorption
spectroscopy, X-ray diffraction (XRD), atomic force microscopy (AFM)
and scanning electron microscopy (SEM). The electrical characteristics of the
devices are measured by using Keithley 2400 SMU and
solar simulator with light intensity of 100 mW/cm2.
