Special Issue Information

Dear Colleagues,

This Special Issue focuses on the polymer thin films and polymer blend films in photovoltaic (PV) structures. Organic materials are widely used today in optoelectronic devices, such as organic solar cells (OSCs), mainly due to the low cost of production (thin films may be deposited at low temperature on a large surface, on flexible substrates). However, polymer compounds in OSC systems also have certain limitations, such as low efficiency and short lifetime of devices, resulting from an insufficient thermal and time stability. Polymers, which may be utilized in PV systems, should exhibit the appropriate optical properties (e.g., a wide range of absorption and low energy gap), good durability and stability (not undergoing any phase transitions or degradation in the temperature range in which the system is working), and relevant electronic structure (good alignment of molecular orbitals of donor and acceptor compounds in bulk heterojunction (BHJ) organic solar cells).

This Special Issue covers all the fields related to polymer films for photovoltaic applications, but special attention will be given to the following aspects:

  • Synthesis and suitable modification of polymer structure, to obtain polymer thin films for PV devices;
  • Influence of film deposition (TVE—thermal vacuum evaporation, CVD—chemical vapor deposition, spin coating, spray, etc.) on properties of polymer films;
  • Thermo-optical properties of polymer thin films and blends of polymer films, as potential parts of PV systems;
  • Influence of doping or protonation of polymer thin films and blend polymer films on their properties;
  • Polymer thin films, as active layers in PV solar cells—correlation of chemical structure and PV properties;
  • BHJ solar cells with polymer blends films—the choice of blend film composition to obtain the best PV parameters.

Authors are welcome to submit their latest research in the form of original full articles, communications, or reviews on this topic.

Generally, polymer-based memory devices store information in a manner distinct from that of silicon-based memory devices. Conventional silicon memory devices store charges as either zero or one for digital information, whereas most polymers store charges by the switching of electrical resistance. For the first time, this study reports that the novel conducting polymer Poly-N-Epoxy-Propyl Carbazole (PEPC) can offer effective memory storage behavior. In the current research, the electrical characterization of a single layer memory device (metal/polymer/metal) using PEPC, with or without doping of charge transfer complexes 7,7,8,8-tetra-cyanoquino-dimethane (TCNQ), was investigated. From the current–voltage characteristics, it was found that PEPC shows memory switching effects in both cases (with or without the TCNQ complex). However, in the presence of TCNQ, the PEPC performs faster memory switching at relatively lower voltage and, therefore, a higher ON and OFF ratio (ION/IOFF ~ 100) was observed. The outcome of this study may help to further understand the memory switching effects of conducting polymer. Full article

The Effect of Alkyl Substitution of Novel Imines on Their Supramolecular Organization, towards Photovoltaic Applications

Abstract
Three novel conjugated polyazomethines have been obtained by polycondensation of diamines consisting of the diimine system, with either 2,5-bis(octyloxy)terephthalaldehyde or 9-(2-ethylhexyl)carbazole-3,6-dicarboxaldehyde. Partial replacement of bulky solubilizing substituents with the smaller side groups has allowed to investigate the effect of supramolecular organization. All obtained [...] Read more.
Three novel conjugated polyazomethines have been obtained by polycondensation of diamines consisting of the diimine system, with either 2,5-bis(octyloxy)terephthalaldehyde or 9-(2-ethylhexyl)carbazole-3,6-dicarboxaldehyde. Partial replacement of bulky solubilizing substituents with the smaller side groups has allowed to investigate the effect of supramolecular organization. All obtained compounds have been subsequently identified using the NMR and FTIR spectroscopies and characterized by the thermogravimetric analysis, differential scanning calorimetry, cyclic voltammetry, UV–Vis spectroscopy, and X-ray diffraction. Investigated polymers have shown a good thermal stability and high glass transition temperatures. X-ray measurements have proven that partial replacement of octyloxy side chains with smaller methoxy groups induced a better planarization of macromolecule. Such modification has tuned the LUMO level of this molecule and caused a bathochromic shift of the lowest energy absorption band. On the contrary, imines consisting of N-ethylhexyl substituted carbazole units have not been so clearly affected by alkyl chain length modification. Photovoltaic activity of imines (acting as a donor) in bulk-heterojunction systems has been observed for almost all studied compounds, blended with the fullerene derivative (PCBM) in various weight ratios.
