“…Device performances are also dependent on the microstructures of thin film configurations, and the morphology can be controlled by additives such as poly(methyl methacrylate) [88][89][90], phthalocyanines [91][92][93][94], or polysilanes [95][96][97]. A large contact area at the TiO 2 /perovskite interface can enhance the probability of carrier separation, which improves the short circuit current density.…”

AbstractThe crystal structures of various types of perovskite halide compounds were summarized and described. Atomic arrangements of these perovskite compounds can be investigated by X-ray diffraction and transmission electron microscopy. Based on the structural models of basic perovskite halides, X-ray and electron diffractions were calculated and discussed to compare with the experimental data. Other halides such as elemental substituted or cation ordered double perovskite compounds were also described. In addition to the ordinary 3-dimensional perovskites, low dimensional perovskites with 2-, 1-, or 0-dimensionalities were summarized. The structural stabilities of the perovskite halides could be investigated computing the tolerance and octahedral factors, which can be useful for the guideline of elemental substitution to improve the structures and properties, and several low toxic halides were proposed. For the device conformation, highly crystalline-orientated grains and dendritic structures can be formed and affected the photo-voltaic properties. The actual crystal structures of perovskite halides in the thin film configuration were studied by Rietveld analysis optimizing the atomic coordinates and occupancies with low residual factors. These results are useful for structure analysis of perovskite halide crystals, which are expected to be next-generation solar cell materials.

“…6 One of the potential inorganic materials that could be blended with polymer materials is perovskite. Perovskite-structured materials have been extensively studied due to their extraordinary optoelectronic characteristics, such as synthetic bandgap tunability, high absorption coefficient, good photoconductivity, and long charge carrier diffusion length with higher lifetimes, [7][8][9] making perovskite materials great for diverse applications, including light-emitting diode (LED), [10][11][12] solar cells, [13][14][15][16] photocatalysis, 17 lasers, 18 and photodetectors. 19 According to recent research, the use of lead (Pb) halide perovskite structured materials in LED devices has been reported to deliver better LED performance.…”

This study reports the performances of a single structured light-emitting diode (LED) devices based on polymer material poly(9,9-di- n-hexylfluorenyl-2,7-diyl) (PHF) mixed with various concentrations of perovskite oxide strontium titanate (SrTiO3) particles deposited as a composite PHF: SrTiO3 emitting layer. The performances of the single structured organic LED indium tin oxide (ITO)/PHF/aluminum (Al) device and the composite LED ITO/PHF: SrTiO3/Al devices were compared in terms of turn-on voltage and luminance intensity. By incorporating perovskite SrTiO3 particles into PHF emitting layer, the turn-on voltage of the device is significantly reduced from 11.25 V to 1.80 V and the luminance intensity increased from 57.7 cd/m2 to 609 cd/m2. The improvement of turn-on voltage and the electroluminescence spectrum of the composite devices were found to be dependent on the weight ratios of SrTiO3 content in the PHF emitting layer.

“…Among numerous organic semiconductors, metal phthalocyanines (MPc) are of particular interest because of their high thermal and chemical stability combined with their unique electronic properties. Being stable organic semiconductors, MPcs are used in energy-conversion devices (photovoltaic and solar cells), optical devices and as active layers of chemical sensors [1][2][3][4]. Films of MPcs are widely used as active layers of chemiresistive sensors [5,6].…”

“…The sensing properties of metal phthalocyanines can also be strongly affected by substituents in benzene rings, e.g., the introduction of electronegative fluorine atoms as well as fluroalkyl and fluoroaryl groups is a powerful tool for tuning MPc properties, especially electrical and sensor characteristics of their films [20,21]. It was shown in previous works [22][23][24] that the introduction of electron-withdrawing fluorine substituents led to an increase of the oxidation potential of the phthalocyanine molecule and, as a consequence, to an increase of the sensitivity of fluorosubstituted metal phthalocyanines to reducing gases like NH 3 and H 2 .…”

In this work, thin films of vanadyl phthalocyanines (VOPc and VOPcF4) are studied as active layers for the detection of gaseous ammonia and hydrogen. The effect of F-substituents on the structural features of vanadyl phthalocyanine films and their sensor response toward ammonia (10–50 ppm) and hydrogen (100–500 ppm) is investigated by X-ray diffraction (XRD) and chemiresistive methods, respectively. It is shown that the sensor response of VOPcF4 films to ammonia is 2–3 times higher than that of VOPc films. By contrast, the sensor response to hydrogen is higher in the case of VOPc films. Apart from this, the hybrid structures of vanadyl phthalocyanine films with Pd nanoparticles deposited on their surface by a chemical vapor deposition method are also tested to reveal the effect of Pd nanoparticles on the sensitivity of VOPc films to hydrogen. Deposition of Pd nanoparticles on the surface of VOPc films leads to the noticeable increase of their sensitivity to hydrogen.
