“…The absorption spectrum was replotted inset Figure 6 as a function of photon energy to determine the interband energy transition, E int , from HOMO to LUMO from the intercept at the energy axis [ 44 ]. It is noted that the value of E int is 1.885 eV lies in the range of semiconducting materials (0.1–3 eV) [ 17 ]. This feature means that charge carriers can contribute to the electrical conductivity due to the creation of an electron–hole upon photon absorption by E143 dye molecules [ 45 ].…”

Organic semiconductors (OSCs) have attracted considerable attention for many promising applications, such as organic light-emitting diodes (OLEDs), organic field-effect transistors (OFETs), and organic photovoltaics (OPVs). The present work introduced E143 food dye as a new nanostructured organic semiconductor that has several advantages, such as low cost, easy fabrication, biocompatibility, and unique physical properties. The material was characterized using a transmission electron microscope (TEM), Fourier transform infrared (FT-IR) spectroscopy, thermogravimetric analysis (TGA), and optical absorption spectroscopy. The study of X-ray diffraction (XRD) showed that E143 dye has a monoclinic polycrystalline structure. Electrical and dielectric properties were performed by impedance spectroscopy at frequencies (20 Hz–1 MHz) in the temperature range (303–473 K). The values of interband transitions and activation energy recommended the application of E143 dye as a new organic semiconductor material with promising stability, especially in the range of hot climates such as KSA.

Optimization of photovoltaic (PV) active layers is usually carried out in terms of the energy bandgap (Eg) variation of the bulk heterojunction (BHJ) layers. However, the non-monotonic change in the Eg does not guarantee the achievement of a maximum absorption capability at the optimum condition despite the broadened absorption spectrum. Hence, alternative strategies need to be researched in order to assign the best possible condition at which the active layer can convert the highest possible number of exposed photons to free electrons when it is employed in PV devices. Therefore, in this work, we propose a new approach which can be effectively used to optimize the BHJ active layers in terms of photon to electron conversion, considering the absorption profile of the system. Herein, area under the curve (AUC) of the absorption profile is utilized to optimize the active layers of photovoltaic devices. To formulate the proposed technique, a ternary system based on P(TRI-co-TER):Beetroot dye:PINDOLE was investigated and analyzed. Results showed that a linear correlation was produced between the AUC and photocurrent density (Jph), which can be ultimately used to optimize the active layers of PV devices.

“…One of these approaches is that the active layer become transparent to the visible part of the solar spectrum. Therefore, the high band gap polymers, dye molecules [15][16][17], and ultra-narrow band gap polymers are utilized to absorb in the UV and IR regions in solar spectrum [18][19][20]. To this end, this study focuses on characterizations of the three newly synthesized polymers which are two electron-rich polymers: (i) Poly (triamterene-co-terephthalate)(P(TRI-co-TER)), (ii) Poly [triamterene-co-3-(2pyridyl)-5, 6-diphenyl-1, 2, 4-triazine-p, p'-disulfonamide] (P(TRI-co-DISULF)) and one electronaccepting polymer: (iii) Poly (5-hydroxyindole-2-carboxylate) (PINDOLE) as host materials for the binary photoactive layers.…”

Organic solar cells are contributing extensively to the production of future large area and cost-effective sources of renewable energy with a compact environmental impact. Moreover, due to tunable optical properties of the active medium, the semi-transparent organic solar cell can be fabricated and become a promising nominee for building Integrated Photovoltaics (BIPV), vehicles, and mobile electronic devices. Therefore, three newly synthesized polymers used as were host materials for the active medium and blended with beetroot dye. Hence, based on BHJ structure two ternary systems have been constructed and utilized to fabricate semitransparent solar cells and characterized. The results show that the natural dye has a crucial impact on solar cell characteristic parameters. Consequently, large value of V_OC close to 1V were obtained for ternary systems and acceptor material named PINDOLE exhibits potentials for electron transport layer (ETL) and shows an improvement in both fill factor and device efficiency.
