“…A new peak appears centered at 169.295 eV which is shifted by about 5.1 eV toward the higher binding energy relative to the original S 2 p 3/2 signal after 15 days. This new signal should be assigned to be a sulphone (-SO 2 -) and is indicative for the oxidation of sulphur atoms of thiophenic ring [ 45 , 46 ]. Therefore, it is inferred from C1s and S 2p spectra that the degradation of aged P3HT-ZnO hybrid thin film occurred in certain degree resulting from the oxidation of P3HT due to the presence of the light or oxygen in the environment.…”

A thin-film transistor (TFT) having an organic–inorganic hybrid thin film combines the advantage of TFT sensors and the enhanced sensing performance of hybrid materials. In this work, poly(3-hexylthiophene) (P3HT)-zinc oxide (ZnO) nanoparticles' hybrid thin film was fabricated by a spraying process as the active layer of TFT for the employment of a room temperature operated formaldehyde (HCHO) gas sensor. The effects of ZnO nanoparticles on morphological and compositional features, electronic and HCHO-sensing properties of P3HT-ZnO thin film were systematically investigated. The results showed that P3HT-ZnO hybrid thin film sensor exhibited considerable improvement of sensing response (more than two times) and reversibility compared to the pristine P3HT film sensor. An accumulation p-n heterojunction mechanism model was developed to understand the mechanism of enhanced sensing properties by incorporation of ZnO nanoparticles. X-ray photoelectron spectroscope (XPS) and atomic force microscopy (AFM) characterizations were used to investigate the stability of the sensor in-depth, which reveals the performance deterioration was due to the changes of element composition and the chemical state of hybrid thin film surface induced by light and oxygen. Our study demonstrated that P3HT-ZnO hybrid thin film TFT sensor is beneficial in the advancement of novel room temperature HCHO sensing technology.

Abstract. An organic-inorganic nanocomposite material of poly (3-decylthiophene) and titanium dioxide doped with N (P3DT/N/TiO 2 ) were synthesized. Structures were characterized using X-ray diffraction (XRD), infrared spectroscopy (IR), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). Optical and electrochemical properties were determined using UV-visible spectroscopy, fluorescence spectroscopy, and cyclic voltammetry. These tests indicated that P3DT/N/TiO 2 was a new p-n semiconductor photoelectric material, and the solar cell prepared with P3DT/N/TiO 2 performed well.

“…7, and all the parameters of PMOT and PMOT/TiO 2 sensitized solar cell is listed in Table 2 short circuit voltage short-circuit current (J sc ) of 0.530 mA/cm 2 , open-circuit voltage (V oc ) of 0.513 V, effective area of 0.66 cm 2 , and fill factor (FF) of 0.449, corresponding to an overall conversion efficiency (Z) of 0.385%, which is higher than the POT/ZnO nanocomposite sensitized solar cell in Ref. [45]. The overall conversion efficiency enhancement of PMOT/TiO 2 relative to PMOT can be related to the chemistry interaction in the composite, which refer to the XPS discussion.…”
