【 摘 要 】

The derivatives of polyaniline have obtained remarkable attention due to their electronic applications in the field of nanomaterials. This work considers the electronic, structural, and photovoltaic properties of nanocomposites (POT/WO3NPs) synthesized with three different ratios of poly(o-toluidine) and WO3 nanoparticles [a-c (molWO3/molmonomer) 100 = 60, 65, 70%] using a template-free method and a basic mechanochemical reaction in solid-state. The nanocomposites are analyzed and characterized by various spectroscopy methods. The prepared nanocomposites have core-shell morphology. The results of the band gap assessed via cyclic voltammetry and UV-vis specified that the forbidden band gap for (POT/WO3NPs) nanocomposite b [(molWO3/molmonomer) 100 = 65%] are about 1.03 and 1.5–1.9 eV, respectively. The J–V analysis and power conversion efficiency of the fabricated devices FTO|TiO2NPs|POT|Al and FTO|TiO2NPs|POT/WO3NPs (a-c) |Al single-layer solar cells are performed and discussed. The photovoltaic energy conversion efficiency (PCE) of the two devices are 0.18% and in average, 0.57%, respectively. The data show both indirect and direct transitions are observed for the WO3NPs, POT, and POT/WO3NP (b). This investigation demonstrates that the morphology and architecture of nanocomposites (POT/WO3NPs) can be helpful in improving solar cell performance.
