Using a simple hydrothermal synthesis, the crystal structure of TiO2 nanoparticles was controlled from rutile to anatase using a sugar alcohol, D-sorbitol. Adding small amounts of D-sorbitol to an aqueous TiCl4 solution resulted in changes in the crystal phase, particle size, and surface area by affecting the hydrolysis rate of TiCl4. These changes led to improvements of the solar-to-electrical power conversion efficiency (η) of dye-sensitized solar cells (DSSC) fabricated using these nanoparticles. A postulated reaction mechanism concerning the role of D-sorbitol in the formation of rutile and anatase was proposed. Fourier-transform infrared spectroscopy, 13C NMR spectroscopy, and dynamic light scattering analyses were used to better understand the interaction between the Ti precursor and D-sorbitol. The crystal phase and size of the synthesized TiO2 nanocrystallites as well as photovoltaic performance of the DSSC were examined using X-ray diffraction, Raman spectroscopy, field-emission scanning electron microscopy, high-resolution transmission electron microscopy, and photocurrent density-applied voltage spectroscopy measurement techniques. The DSSC fabricated using the anatase TiO2 nanoparticles synthesized in the presence of D-sorbitol, exhibited an enhanced η (6%, 1.5-fold improvement) compared with the device fabricated using the rutile TiO2 synthesized without D-sorbitol.

“…In recent research, PEDOT: PSS is a new type of organic conductive polymer that often used in printable, flexible temperature sensors [124]. Generally speaking, PEDOT: PSS has the advantages of high conductivity ( 10 3 S cm −1 ), excellent thermoelectric performance [125][126][127][128], strong stability [123,129], and transparency when doped [60]. Most polymers are p-type semiconductors.…”

In recent years, the development and research of flexible sensors have gradually deepened, and the performance of wearable, flexible devices for monitoring body temperature has also improved. For the human body, body temperature changes reflect much information about human health, and abnormal body temperature changes usually indicate poor health. Although body temperature is independent of the environment, the body surface temperature is easily affected by the surrounding environment, bringing challenges to body temperature monitoring equipment. To achieve real-time and sensitive detection of various parts temperature of the human body, researchers have developed many different types of high-sensitivity flexible temperature sensors, perfecting the function of electronic skin, and also proposed many practical applications. This article reviews the current research status of highly sensitive patterned flexible temperature sensors used to monitor body temperature changes. First, commonly used substrates and active materials for flexible temperature sensors have been summarized. Second, patterned fabricating methods and processes of flexible temperature sensors are introduced. Then, flexible temperature sensing performance are comprehensively discussed, including temperature measurement range, sensitivity, response time, temperature resolution. Finally, the application of flexible temperature sensors based on highly delicate patterning are demonstrated, and the future challenges of flexible temperature sensors have prospected.

The implementation of flexible Organic Electronic (OE) devices in a large variety of consumer applications (generation of electricity, visualization of information, lighting, sensing, etc.) will significantly improve our everyday life. The typical OE device (e.g. a organic photovoltaic cell-OPV) consists of multilayered structures (30-200 nm thick each) fabricated onto rigid (e.g. glass) and/or flexible substrates (as PET, PEN) from transparent and electrically active organic nanolayers. The OE device core is the active or the organic semiconducting (polymer or small molecules) layer, that absorbs photons and generates electric charges, sandwiched between the device electrodes. Finally, the device is encapsulated by barrier layers for the protection of the photoactive layers against degradation and corrosion due to atmospheric gas penetration inside the device.The understanding of the correlation between the polymer blend structure and its optical and electrical properties, and the achievement of the desirable morphology at nanometer scale, is a prerequisite in order to optimize the device performance and stability. Spectroscopic Ellipsometry (SE) from the infrared to the visible and far ultraviolet spectral region has been widely used to provide significant insights on the optical properties, blend morphology, and composition of the polymer blends that are used as active layers in OE devices. In this chapter, we summarize on the latest advances in the implementation of SE from the infrared to the visible and ultraviolet spectral region, for the investigation of the optical and electronic properties, composition profile and structure of polymer nanomaterials that are used as organic semiconductors and transparent electrodes for OE devices, and we discuss the effect of their nanoscale structure on their properties and functionality.
