Nanostructured organic-inorganic photodiodes with high rectification ratio

High quality organic-inorganic heterojunction photodiodes based on nanostructured copper (II) phthalocyanine (CuPc) and intrinsic zinc oxide (i-ZnO) have been fabricated. The i-ZnO thin films/layers were grown by RF magnetron sputtering on clean indium tin oxide (ITO) coated glass substrates. These films have been characterized by optical absorption and field emission scanning electron microscopy (FESEM). CuPc thin films deposited at room temperature on i-ZnO have exhibited a change in their surface morphology with the post-deposition annealing temperature under normal atmosphere. The electrical dark conductivity and the photoconductivity of ITO/i-ZnO/CuPc/Au sandwich structures have been measured under various photoexcitation intensities using a xenon light source. The devices have shown excellent reproducibility of their electrical characteristics and high rectification ratios. The highest rectification ratio is nearly 831 calculated above the threshold voltage at room temperature for the sample annealed at 250?°C (i.e.?Pc 250). The effects of the annealing temperature of CuPc on the surface morphology, rectification ratio, and optical properties have been discussed.

Photoconductivity of iodine-doped single crystals of phthalocyanine

Single crystals of metal-free phthalocyanine (H₂Pc) and of copper phthalocyanine (CuPc) were grown in the presence of iodine vapour. The presence of iodine enhances the spectral dependence of photoconductivity of H₂Pc in the visible region but of CuPc in the near-IR region. The dark current is decreased but the photocurrent is increased by one order of magnitude in iodine-doped H₂Pc but in the case of iodine-doped CuPc both currents are increased by nearly three orders of magnitude. Introduction of iodine results in about one order of magnitude decrease in response time for both modifications. Thus the introduction of iodine into Pc crystals decreases the energy barrier for conduction and increases the drift mobility of charge carriers thereby enhancing the conductivity of the material.     

Fabrication and characterization of tetracyanoquinodimethane/phthalocyanine solar cells

Fabrication and characterization of heterojunction solar cells of tetracyanoquinodimethane (TCNQ)/copper phthalocyanine (CuPc) and zinc phthalocyanine (ZnPc) were carried out. The light-induced charge separation with charge transfer was investigated by light-induced current density and optical absorption. In both cases of the TCNQ/CuPc and TCNQ/ZnPc solar cells, the TCNQ thin film worked for strong electron-accepting layer as n-type semiconductor. These behaviors would be originated in charge transfer of excited electron from CuPc and ZnPc to TCNQ. The photovoltaic mechanism was discussed on the basis of the experimental results.

Fabrication and photovoltaic properties of fullerene and copper phthalocyanine derivative mixed Langmuir-Schaefer films

Surface pressure-area isotherms of mixed floating film of fullerene (C₆₀) and tri-(2,4-di-t-amylphenoxy)-(8-quinolinolyl) copper phthalocyanine (CuPc) were investigated at different molar compositions at air-water interface. The shapes of these isotherms and estimated areas per molecule are shown dependent on the molar compositions. C₆₀/CuPc mixed multilayers were fabricated onto various solid substrates by using Langmuir-Schaefer (LS) technique, and characterized by UV-VIS spectroscopy, electrochemical and photoelectrochemical measurements respectively. Uniform LS films were formed when the molar composition was less than 1 : 1 (C₆₀: CuPc). UV-VIS spectroscopic measurements showed that there was no distinct interaction between phthalocyanine and C₆₀molecules at ground state either in solution or in solid films. However, electron transfer appears to have occurred between two kinds of molecules under light illumination. Photoelectrochemical study revealed that phthalocyanine and C₆₀mixed system could be a potential candidate for photovoltaic applications.     

Electronic absorption band broadening and surface roughening of phthalocyanine double layers by saturated solvent vapor treatment

Variations in the electronic absorption (EA) and surface morphology of three types of phthalocyanine (Pc) thin film systems, i.e. copper phthalocyanine (CuPc) single layer, zinc phthalocyanine (ZnPc) single layer, and ZnPc on CuPc (CuPc/ZnPc) double layer film, treated with saturated acetone vapor were investigated. For the treated CuPc single layer film, the surface roughness slightly increased and bundles of nanorods were formed, while the EA varied little. In contrast, for the ZnPc single layer film, the relatively high solubility of ZnPc led to a considerable shift in the absorption bands as well as a large increase in the surface roughness and formation of long and wide nano-beams, indicating a part of the ZnPc molecules dissolved in acetone, which altered their molecular stacking. For the CuPc/ZnPc film, the saturated acetone vapor treatment resulted in morphological changes in mainly the upper ZnPc layer due to the significantly low solubility of the underlying CuPc layer. The treatment also broadened the EA band, which involved a combination of unchanged CuPc and changed ZnPc absorption.     

Purification and characterization of phthalocyanines

The technical details of a simple train sublimation (carrier gas) system for purification of organic materials are given and the refining procedure is described.

It was found that train sublimation improves the quality of the pigments considerably. Spectroscopic results indicate the presence of a second phase in the purified MgPc.     

Utilization of copper phthalocyanine and bathocuproine as an electron transport layer in photovoltaic cells with copper phthalocyanine/buckminsterfullerene heterojunctions: Thickness effects on photovoltaic performances

In this work, copper phthalocyanine (CuPc) and bathocuproine (BCP) were used as electron transport layers (ETL) in organic photovoltaic (PV) cells with a structure of indium-tin-oxide/CuPc/C60/ ETL/Al. It was found that PV performance was sensitive to the ETL thickness. A complete coverage of ETL on the C60 film was essential to avoid an insulative C60/Al contact. ETL thickness of 6 nm resulted in optimal PV performance. The PV cells with BCP layers of 2-10 nm demonstrated good PV performance due to efficient electron transport from C60 to Al cathode. Similar result was obtained from the devices with CuPc ETL. However, thicker ETL resulted in considerable lose in PV performance. In both cases, different mechanisms responsible for the dependence of PV performance on ETL thickness are discussed.
