Functionalized fullerenes are known as high-performance molecules. Herein, the interaction of C60 fullerene with Phenyl-C61-butyric-acid-methyl-ester (PCBM) is investigated by means of density functional theory (DFT) method to elucidate the structures and electronic states of C60-PCMB complexes. C60-PCBM blends are typically used in solar cell. Studying the electronic structure of C60-PCBM is important for elucidating the mechanism of solar cells. The intermolecular distances for C60 and PCBM dimers were calculated to be 3.70 and 2.34 Å, respectively. In C60 dimer, the five membered ring of C60 interacted with the six membered ring of neighbour C60. Two hydrogen bonds between side chains of PCBM are connected in the PCBM dimer. The binding energies were 1.4 kcal/mol (C60 dimer) and 2.6 kcal/mol (PCBM dimer). In the C60-PCBM complex, five different structures were found to be stable. The binding energies were distributed in the range 1.6-3.7 kcal/mol. The electronic states and excitation energies of C60-PCBM complexes and the basis set superposition error (BSSE) were discussed on theoretical results.

“…Additionally, conducting polymers such as poly(3,4-ethylenedioxythiophene) (PEDOT) have been explored as potential radiation detectors due to their response to ionizing radiation (Zhang & Yeow, 2020). In our previous study, we investigated the X-ray detection properties of a blend structure of Poly(3-hexylthiophene) (P3HT):Phenyl C61 butyric acid methyl ester (PCBM) with varying PCBM loading ratios (Kalkan et al, 2022). The use of polymer materials in radiation detectors offers several potential advantages over traditional inorganic materials, particularly in terms of cost and flexibility, making it a highly active area of research in recent years.…”

This study investigates the potential use of lignocellulosic material for Gas Electron Multiplier (GEM) foils in high-energy physics experiments. A 50 µm thick lignocellulosic film was created using a scattering method, and both surfaces were coated with a 2 µm thick copper electrode layer. Electrical characterization studies were conducted to assess the suitability of lignocellulosic material in GEM detectors. To ensure consistent atmospheric conditions during measurements, a special chamber was designed to monitor temperature and humidity values over time using an SHT3x sensor module and Rense Temperature/Humidity Meter. Electrical measurements were performed using a Keithley 4200 semiconductor characterization system, and I-V curves showing the current-voltage relationship under different atmospheric conditions were plotted. The results demonstrate the potential for developing sustainable and efficient detectors for various high-energy physics experiments using GEM detectors with lignocellulosic foils. This study comprehensively presents the advantages and disadvantages of using lignocellulosic material in GEM foils and contributes to the development of more environmentally friendly alternatives for GEM detector manufacturing.

Solar cells convert light energy directly into electricity using semiconductor materials. The ternary system, composed of poly(3-hexylthiophene) (P3HT), fullerene (C60), and phenyl-C61-butyric-acid-methyl-ester (PCBM), expressed as P3HT-C60-PCBM, is one of the most efficient organic solar cells. In the present study, the structures and electronic states of P3HT-C60-PCBM have been investigated by means of the density functional theory (DFT) method to shed light on the mechanism of charge separation in semiconductor materials. The thiophene hexamer was used as a model of P3HT. Five geometrical conformers were obtained as the C60-PCBM binary complexes. In the ternary system, P3HT wrapped around C60 in the stable structure of P3HT-C60-PCBM. The intermolecular distances for P3HT-(C60-PCBM) and (P3HT-C60)-PCBM were 3.255 and 2.885 Å, respectively. The binding energies of P3HT + (C60-PCBM) and (P3HT-C60) + PCBM were 27.2 and 19.1 kcal/mol, respectively. The charge transfer bands were found at the low-lying excited states of P3HT-C60-PCBM. These bands strongly correlated with the carrier separation and electron transfer in solar cells. The electronic states at the ground and excited states of P3HT-C60-PCBM were discussed on the basis of the calculated results.
