Synthesis and application of the solar cell of poly(3-hexylthiophene)/Fe N/titanium dioxide nanocomposite material Original Research Article

A series of nanocomposites of poly(3-hexylthiophene) with Fe N-doped TiO2 (P3HT/Fe N/TiO2) were synthesized by the chemical method in situ. The structure of the prepared composites was characterized using X-ray diffraction patterns (XRD), infrared spectroscopy (IR), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Optical and electrochemical properties were determined using UV–vis spectroscopy, fluorescence spectroscopy, and cyclic voltammetry. These tests indicated that P3HT/Fe N/TiO2 is a new p–n semiconductor. Two solar cells based on P3HT/Fe N/TiO2 were manufactured and studied.
