“…It is clear that carbon nanotube films function, at least, as transparent conducting front electrodes. Carbon nanotube films have been used similarly in amorphous silicon solar cells,75 heterojunction solar cells of quantum dots and silicon,76 on silicon nanowires with77 and without78 photoactive polymers, as well as enhancing the performance of ‘standard’ p‐n junction silicon solar cells 79. Photovoltaic output from NSH cells can be improved by the addition of graphene ‘patches’ to the nanotube film80 and by flowing gasses over the surface of the nanotube film, an effect that has been explored in the fabrication of gas sensors 81…”

Due to the high cost of silicon photovoltaics there is currently great interest in finding alternative semiconductor materials for light harvesting devices. Single‐walled carbon nanotubes are an allotrope of carbon with unique electrical and optical properties and are promising as future photovoltaic materials. It is thus important to investigate the methods of exploiting their properties in photovoltaic devices. In addition to already extensive research using carbon nanotubes in organic photovoltaics and photoelectrochemical cells, another way to do this is to combine them with a relatively well understood model semiconductor such as silicon. Nanotube‐silicon heterojunction solar cells are a recent photovoltaic architecture with demonstrated power conversion efficiencies of up to ∼14% that may in part exploit the photoactivity of carbon nanotubes.

“…Several studies have reported on a-Si:H and other organic conductive polymers such as PEDOT:PSS, P3HT, PCBM, MEH-PPV, PCPDTBT HSCs, and more recently, polypyrole/a-Si HSC [2][3][4][5][6][7][8] with photo-conversion efficiencies not exceeding 3%. On the other hand, carbon-based nanomaterials, for example, carbon nanotubes (CNTs), have made a valuable contribution to recent advances in the field of solar cell development in C-Si [9][10][11], CNT-polymer [12], and more recently in perovskite-based [13] solar cells. Furthermore, there are several reports showing improvements in HSC efficiency by the use of CNTs and conductive polymers such as PEDOT: PSS [14,15].…”

We report a simple approach to fabricate hybrid solar cells (HSCs) based on a single-walled carbon nanotube (SWCNT) film and a thin film hydrogenated amorphous silicon (a-Si:H). Randomly oriented high quality SWCNTs with an enhanced conductivity by means of poly(3,4-ethylenedioxythiophene) polystyrene sulfonate are used as a window layer and a front electrode. A series of HSCs are fabricated in ambient conditions with different SWCNT film thicknesses. The polymethylmethacrylate layer drop-casted on fabricated HSCs reduces the reflection fourfold and enhances the short-circuit Jsc, open-circuit Voc, and efficiency by nearly 10%. A state-of-the-art J-V performance is shown for SWCNT/a-Si HSC with an open-circuit voltage of 900 mV and efficiency of 3.4% under simulated one-sun AM 1.5G direct illumination.

“…[18][19][20] Therefore, in continuation of our previous studies in computational chemistry, 21,22 especially on the study of noncovalent interactions, [14][15][16] we have decided to attempt a complete study on the interactions of SFs with halogens and halides using appropriate DFT calculations. Because, despite the fact that there are several studies on the adsorption or sensor potencies of simple and doped fullerenes (or other nanostructures), [23][24][25][26] by reviewing the literature, it was found that there are no reports related to the interaction of halogens or halide anions with doped fullerenes.…”

This work reports study on the interactions of sulfur-doped fullerenes with halogens and halides (except iodine and iodide) to gain an enlightened vision to such interactions for employing them in possible applications such as sensor and surface adsorption. The ωB97XD DFT code has utilized in this study to obtain adsorption energies in the gas phase and solvent. The energy outcomes showed proper results for adsorptions in both gas and solvent (using PCM model). However, the gas phase interactions are more favorable thermodynamically. The formation of halide complexes releases more energy than the formation of halogen complexes and the strongest interaction is belong to the interactions of disulfur-doped fullerenes with halides. Donor-Acceptor transitions mostly affected by sulfur doping, which made C-S bond as auxiliary tool for the absorption process. The density of states (DOS) plots demonstrated better modification of conductivity properties upon sulfur-doping on fullerene structures. Electron densities and their Laplacians at bond critical points (BCPs) of interaction sites, NCI calculations and further visualizations proved the existence of such these interactions, clearly indeed. It's worthy to point that, in some cases, something like partial functionalization of fullerene have seen and these observations were approved via QTAIM, NCI and energy data. In these cases, the stable and thermodynamically favorable cation of halogenated doped fullerene (along with X3ˉ as counter ion) could be produced from the interaction of double-doped fullerene with two molecular halogens.Please do not adjust margins Please do not adjust margins noncovalent interaction isosurface for one halogen atom in S2F1-DP-X 2 (X=F, Cl, Br) which refer to lack of such interaction in this case (and existing covalent bond). Although, there are much more troughs in negative area of electron density for S2F1-DP-X 2 (X=F, Cl, Br) complexes in figure 6 that could assign to more attractive interactions in those models.
