“… 20 Consequently, significant interest has been generated for the study of the electrical properties of Pc compounds and their derivatives. Khalil et al 21 have deposited 4-tetra-4-tolylsulfonyl:zinc phthalocyanine (4T4TS:ZnPc) thin films by the spin coating technique on quartz substrates. The authors reported that the X-ray diffraction (XRD) spectra of 4T4TS:ZnPc showed a monoclinic crystalline structure in phase with a preferential orientation along (002) and (1̅02).…”

In this study, we investigated the potential of palladium tetrakis (imidazole) phthalocyanine (PdPc(Imz) 4 ) for use as an organic semiconductor for improving the photovoltaic performance. In order to get more information about the prevailing model of the conduction mechanism (correlated barrier hopping (CBH)) for PdPc(Imz) 4 , electrical impedance measurements were performed at different temperatures and the obtained data were simulated by the Kohlraush Williams Watt (KWW) approach. Theoretical studies (density functional theory (DFT)) were performed and molecular electrostatic potential (MEP) maps were also extracted to understand the relationship between the molecular structures and the molecular electronic structure of PdPc(Imz) 4 and its semiconductor properties. Furthermore, studies on the AC electrical process as a function of temperature highlighted a hopping charge transport according to an equivalent electrical circuit composed of a parallel constant-phase element (CPE), capacitance in the grain boundary layer ( C g ), and resistance of the grain boundary ( R g ). To improve interpretation of the results, an in-depth analysis of the behavior of the electric transport was conducted. As a result, the correlated barrier hopping (CBH) conduction mechanism was shown to be the most suitable predominant conduction mechanism.

“…Q band is the excitonic transitions or vibronic states that represents the first π-π* of fluorinated phthalocyanine materials. The second energy band gap is named B band correspond to electronic transition from π-π* that represents by a second single peak in energy band gap Eg = 3.26 eV in the UV-vis region [24,25].

“…These are a few of their interesting properties that make them good candidates for electronic devices [20,24,25], and furthermore for solar cells [21,[26][27][28][29], where they can be alternately incorporated by doped and undoped MPc layers for heterostructure solar cells [30,31]. Among many MPcs, copper phthalocyanine (CuPc) and zinc phthalocyanine (ZnPc) have been widely studied as potential materials for solar cells due to their appealing photovoltaic and photoconductive properties [32][33][34][35]. Furthermore, indium(III) phthalocyanine chloride (InClPc) Schottky barrier devices have been investigated, which show a promising optoelectronic performance for solar cells and nonlinear optic devices, employing this material as the active layer [24,[32][33][34]36].…”

Herein, we present the photovoltaic properties of an indium phthalocyanine chloride (InClPc)-based flexible planar heterojunction device, introducing the tetrathiafulvene derivative 4,4′-Dimethyl-5,5′-diphenyltetrathiafulvalene (DMDP-TTF) as the electron donor layer. UV-vis spectroscopy is widely used to characterize the electronic behavior of the InClPc/DMDP-TTF active layer. The interactions between the DMDP-TTF and phthalocyanine are predominantly intermolecular and the result of the aggregation of InClPc. Tauc bands were obtained at 1.41 and 2.8 eV; these energy peaks can result in a charge transfer ascribed to the transition from the DMDP-TTF to π-orbitals that are associated with the phthalocyanine ring or even with the same indium metal center. Conductive carbon (CC) was used for the cathode. Finally, an indium tin oxide (ITO)/InClPc/DMDP-TTF/CC device was fabricated by high-vacuum thermal evaporation onto a flexible substrate and the photovoltaic properties were evaluated. A diode type I-V curve behavior was observed with a photovoltaic response under illumination. A generated photocurrent of 2.25 × 10−2 A/cm2 was measured. A conductivity reduction with the incident photon energy from 1.61 × 10−7 S/cm to 1.43 × 10−7 S/cm is observed. The diode resistance presents two different behaviors with the applied voltage. A VTFL of 5.39 V, trap concentration of 7.74 × 1016 cm−3, and carrier mobility values of ~10−6 cm2/V s were calculated, showing improved characteristics via the innovative implementation of an alternative TTF-derivative, indicating that the DMDP-TTF has a strong interaction at the junction where free available states are increased, thus inducing higher mobilities due to the large number of π-orbitals, which indicates the feasibility of its use in solar cells technology.
