“…Metal-substituted and metal free phthalocyanine are readily used as active layer in several applications such as gas sensors, photocopacitive and photoresistive detectors, Organic thin film Transistors (OTFT) [7], colour filters and organic laser materials. Among the various metal-substituted phthalocyanine, Copper phthalocyanine is one of the metal phthalocyanines.…”

In the present paper, Copper Phthalocyanine (CuPc) thin films were deposited on glass and silicon substrate by thermal evaporation and pulsed laser deposition (PLD) methods. CuPc thin films prepared at different annealing temperatures (298, 323, 348, 373, 423 K) respectively. The structure and surface morphology of CuPc in powder and thin films forms prepared by two methods were studied using Energy dispersive X-ray (EDX), X-ray florescence (XRF), X-ray diffraction (XRD), Atomic force microscope (AFM), and Scanning electron microscope (SEM). It showed that there was a change and enhancement in the crystallinity and surface morphology due to change in the annealing temperature (Ta). The purpose of our work is to find the optimal temperature for which the film produces best structural properties for CuPc thin film to produce organic field effect transistor. Analysis of X-ray diffraction patterns of CuPc in powder form showed that it had an α-polycrystalline phase with monoclinic structure, with preferentially oriented (100) plane transform to β-single crystalline morestable structure at different annealing temperatures.

The cobalt phthalocyanine (CoPc) thin films (300 nm thick) deposited on n-type silicon substrate have been studied using micro-Raman spectroscopy, atomic force spectroscopy (AFM) and I-V measurement. The CoPc thin layers have been deposited at room temperature by the quasi-molecular beam evaporation technique. The micro-Raman spectra of CoPc thin films have been recorded in the spectral range of 1000 cm −1 to 1900 cm −1 using 488 nm excitation wavelength. Moreover, using surface Raman mapping it was possible to obtain information about polymorphic forms distribution (before and after annealing) of metallophthalocyanine (α and β form) from polarized Raman spectra. The I-V characteristics of the Au/CoPc/n-Si/Al Schottky barrier were also investigated. The obtained results showed that influence of the annealing process plays a crucial role in the ordering and electrical conductivity of the molecular structure of CoPc thin films deposited on n-type silicon substrate.

“…Low mobility is a significant disadvantage for organic semiconductors compared to inorganic semiconductors [7]. Zinc Phthalocyanine (ZnPc) is the most used organic compounds as an effective layer in photovoltaic solar cells (PSCs) owing to its multiple maximum absorptions in the visible part of the solar spectrum (less than 700 nm) [8][9][10]. ZnO was the most frequently used as electron transport layer (ETL) products for inverted solar cells owing to the elevated optical transparency in the visible and near-infrared area, as well as the elevated mobility of carriers [11].…”

Hybrid bilayer heterojunction Zinc Phthalocyanine (ZnPc) thin-film P-type is considered as a donor active layer as well as the Zinc Oxide (ZnO) thin film n-type is considered as an acceptor with (Electron Transport Layer). In this study, using the technique of Q-switching Nd-YAG Pulsed Laser Deposition (PLD) under vacuum condition 10-3 torr on two ITO (Indium Tin Oxide) and (AL) electrodes and aluminum, is used to construct the hydride bilayer photovoltaic solar cell heterojunction (PVSC). The electrical properties of hybrid heterojunction Al/ZnPc/ZnO/ITO thin film are studied. The results show that the voltage of open circuit (V_oc=0.567V), a short circuit (I_sc=36 ?A), and the fill factor (FF) of 0.443. In addition, the conversion efficiency of (n=3.4%) is recorded with Xenon lamp with an intensity 235mw/cm2 .
