Special Issue Information

Dear colleagues,

The Guest Editor is inviting submissions for a Special Issue of Energies on the subject area of “Advanced Optoelectronic Applications of Novel Organic Semiconductors"

The tremendously rapid progress in the field of organic electronics has promoted unprecedented opportunities for the novel design of electronic devices exploiting the electronic/ionic conduction in π-conjugated organic semiconductors. Indeed, combining high electrical conductivity with mechanically flexible organic materials has opened the door to various innovative applications having a major impact on several fields, from lighting and energy-harvesting technologies to biomedical applications. While most of the potential advantages of organic electronics were asserted decades ago, organic light-emitting diodes are the only organic optoelectronic application to have successfully entered the market. However, after over thirty years of intense research, we are now beginning to see novel organic electronics approaching commercialization. Organic semiconductors promote infinite possibilities to create new materials with tailored optoelectronic properties. Every day, new materials are being added to the existing family of organic semiconductors. Their application in optoelectronic devices such as solar cells and light-emitting diodes continuously improve our understanding in relevant structure–property relationships. This insight then provides critical feedback for the development of next-generation organic materials, with a beneficial effect on the performances and wider potential for real life applications. In this Special Issue, we will focus on any relevant optoelectronic device applications based on organic materials. Topics of interest for publication include but are not limited to the following:.

  • Organic solar cells;
  • Polymer solar cells;
  • Hybrid organic–inorganic solar cells;
  • Non-fullerene organic solar cells;
  • Non-fullerene polymer solar cells;
  • Tandem organic solar cells;
  • Tandem polymer solar cells;
  • Organic light-emitting diode;
  • Polymer light-emitting diode;
  • Hybrid organic–inorganic light emitting diode.

In this study, the performance of an organic dye obtained from the bark of the red pine (Pinus brutia) tree growing in Muğla/Turkey as an interface layer in the Au/n-Si Schottky diode (SD) structure was evaluated. For this purpose, at first, the optimized molecular structure, the highest occupied molecular orbital (HOMO), and the lowest unoccupied molecular orbital (LUMO) simulations of the organic dye were calculated by the Gauss program and it was theoretically proven that the dye exhibits semiconducting properties. Then, the electrical and photodiode variables such as ideality factor, effective barrier height, series resistance, interface states density distribution, photosensitivity, and photo responsivity were evaluated employing current-voltage measurements under dark and different illumination densities. Additionally, C-V measurements were used to demonstrate that the fabricated device has capacitive features and this capability varies as a function of the frequency. Under these measurements, the possible conduction mechanism for the organic dye-based Au/n-Si device was investigated and the results showed that Au/Pinus brutia/n-Si may be a good candidate for optoelectronic applications.

Organic solar cells (OSCs) are an attractive technique for next-generation renewable energy. However, the intrinsically unstable nature of the organic compounds involved is delaying their commercialization. Therefore, it is essential to improve the lifetime of OSCs significantly. Here, we investigated the effect of the hydrophobic cyclized transparent optical polymer (CYTOP) as a solution-processable encapsulation layer based on shelf lifetime measurement, current–voltage characteristics, and impedance spectroscopy. We found that CYTOP utilization greatly enhanced OSCs’ shelf lifetime, maintaining 96% of initial performance when unencapsulated devices decreased to 82%. Furthermore, based on the dark current characteristics, ideality factor (n), and Cole–Cole plots, the CYTOP encapsulation is revealed to effectively inhibit unfavorable changes of parasitic resistive components and trap-assisted recombination. These findings provide an inclusive perspective on the shelf lifetime issue and commercialization of the OSCs. Full article
