“…The P 3 HT polymer exhibited vibration bands at 2954 and 3054 cm −1 corresponding to the stretching and asymmetric vibrations of =C-H and C=C [ 40 , 41 ]. The band at 1260 cm −1 corresponded to the dipole-derivative vector perpendicular to the ring plane, and the band near 1048 cm −1 was due to C-H in-plane bending [ 42 ]. The vibration mode at 1454 cm −1 was due to the deformation vibrations of the CH and CH 3 [ 41 ].…”

In this study, polymer solar cells were synthesized by adding Sb2S3 nanocrystals (NCs) to thin blended films with polymer poly(3-hexylthiophene)(P3HT) and [6,6]-phenyl-C61-butyric-acid-methyl-ester (PCBM) as the p-type material prepared via the spin-coating method. The purpose of this study is to investigate the dependence of polymer solar cells’ performance on the concentration of Sb2S3 nanocrystals. The effect of the Sb2S3 nanocrystal concentrations (0.01, 0.02, 0.03, and 0.04 mg/mL) in the polymer’s active layer was determined using different characterization techniques. X-ray diffraction (XRD) displayed doped ratio dependences of P3HT crystallite orientations of P3HT crystallites inside a block polymer film. Introducing Sb2S3 NCs increased the light harvesting and regulated the energy levels, improving the electronic parameters. Considerable photoluminescence quenching was observed due to additional excited electron pathways through the Sb2S3 NCs. A UV–visible absorption spectra measurement showed the relationship between the optoelectronic properties and improved surface morphology, and this enhancement was detected by a red shift in the absorption spectrum. The absorber layer’s doping concentration played a definitive role in improving the device’s performance. Using a 0.04 mg/mL doping concentration, a solar cell device with a glass /ITO/PEDOT:PSS/P3HT-PCBM: Sb2S3:NC/MoO3/Ag structure achieved a maximum power conversion efficiency of 2.72%. These Sb2S3 NCs obtained by solvothermal fabrication blended with a P3HT: PCBM polymer, would pave the way for a more effective design of organic photovoltaic devices.

Silsesquioxanes (SSQs), with the general formula, (RSiO1.5)n—where R stands for an organic group, such as alkyl, aryl, alkoxy, or H—are a type of molecular‐level organic/inorganic hybrid silica‐based material. These materials contain reactive or nonreactive organic moieties as well as inorganic Si–O–Si frameworks. In the past few years, extensive efforts have been made using SSQs to construct multifunctional nanocomposites with suitable properties for a range of applications. In this review, the recent various applications of SSQ‐containing hybrid materials are discussed, in addition to updates of the nanocomposite applications. Various physical structures and chemical reactions in SSQ‐based hybrid nanomaterials are emphasized with regard to applications in the field of polymer nanocomposites, catalysts, adsorption, sensors, and biomedicine. This review focuses on results reported in the recent five years (2013–2018).
