“…8 Moreover, taking into account their low toxicity, 9 they can be used in pharmacies as drug carriers. 10,11 Furthermore, the unique electronic structure of SWCNHs leads to the nanohorns' possible applications as electrode modification in high-power supercapacitors, 12−14 energy storage devices 15 dyesensitized solar cells, 1,16,17 and field emission devices. 18 In many applications, to minimalize the size, mass, and cost of final devices, it is desired to create thin films of nanomaterials.…”

“…However, the synthesis of carbon nanomaterials usually requires the use of a catalyst polluting the final product and/or is very time- and energy-consuming. One of the few exceptions is single-wall carbon nanohorns (SWCNHs), which are commonly synthesized via CO 2 laser ablation of graphite in a controlled atmosphere without the need for a catalyst . The SWCNHs are tiny graphene sheets, wrapped to form horn-shaped cones of 2–5 nm typical diameters, lengths of 40–50 nm, and cone angles of approx.…”

A suspension of single-walled carbon nanohorn (SWCNH) aggregates with a size of approx. 50 nm was used to create a floating film at the water–air interface. The film was then transferred onto large-area quartz substrates using the Langmuir–Schaefer technique at varied surface pressures. The packaging and arrangement of SWCNHs in the film can be controlled during the process. The resulting films’ optical and electrical properties were investigated, and the highest electrical conductivity and figure of merit parameter values were observed for the film transferred at surface pressure near the collapse point. These films had a surface density of less than 5 μg cm–2, making them ideal for use in ultra-light sensors, supercapacitors, and photovoltaic cell electrodes. The preparation and properties of the Langmuir–Schaefer films of carbon nanohorns are reported for the first time.

“…The development of bifacial DSSM provides a potential candidate for building integrated photovoltaics (BIPVs). − The bifacial BIPV structure enables light energy from direct sunlight (coming from outside) and diffused light (indoor light) to be converted into electric power. DSSCs are recognized as the best choice for indoor light conversion (∼ 200–1000 lx radiance). − The DSSC is an ideal substituent for charging in tiny electronic gadgets under indoor light conditions.…”

The present work demonstrates the high photovoltaic power conversion efficiency (PCE) of 11.12% using single wall carbon nanohorn assisted carbon counter electrode based dye sensitized solar cells (DSSCs), which demonstrates a superior PCE compared to that of platinum (9.41%). This superior performance was a motivation to fabricate a dye sensitized solar module (DSSM) consisting of six series connected DSSCs arranged in a bifacial manner toward the application of building integrated photovoltaics. The DSSM demonstrated a remarkable, champion PCE of 19.71%. This high PCE, driven to fabricate an integrated device (photocapacitor), consists of a DSSM and a supercapacitor (SC). Upon two-sided illumination, the DSSM generated electrical power, and the same power is used for charging the supercapacitor. A working light emitting diode is demonstrated with discharge of the SC. The detailed fabrication strategies and results are discussed.

“…Single-walled carbon nanohorns (SWCNHs), also known in the literature as nanocones, are carbon nanostructures with a particular morphology and were first reported by Iijima and co-workers in 1998 [32]. SWCNHs consist of sp 2 hybridized carbon atoms that form a conical molecular architecture of 2-5 nm in diameter and 30-50 nm in length [33,34]. These structures have some outstanding characteristics: facile synthesis methods, availability of high-purity samples, high chemical and thermal stability, large specific surface area, good electrical conductivity, high porosity, and versatile covalent and noncovalent functionalization [35].…”

Ternary Nanocomposites Based on Oxidized Carbon Nanohorns as Sensing Layers for Room Temperature Resistive Humidity Sensing

et al. 2021

This paper presents the relative humidity (RH) sensing response of a resistive sensor employing sensing layers based on a ternary nanocomposite comprising graphene oxide-oxidized carbon nanohorns-polyvinylpyrrolidone (GO-CNHox–PVP), at 1/1/1, 1/2/1, and 1/3/1 w/w/w mass ratios. The sensing structure is composed of a silicon substrate, a SiO2 layer, and interdigitated transducers (IDT) electrodes, on which the sensing layer is deposited via the drop-casting method. The morphology and the composition of the sensing layers are investigated through scanning electron microscopy (SEM) and RAMAN spectroscopy. The RH sensing capability of each carbonaceous nanocomposite-based thin film was analyzed by applying a current between the two electrodes and by measuring the voltage difference when varying the RH from 0% to 100% in humid nitrogen. The sensors have a room temperature response comparable to that of a commercial humidity sensor and are characterized by a rapid response, excellent linearity, good sensitivity, and recovery time. The manufactured sensing devices’ transfer functions were established, and we extracted the response and recovery times. While the structures with GO/CNHox/PVP at 1/1/1 ratio (w/w/w) had the best performance in terms of relative sensibility, response time, and recovery time, the sensors employing the GO/CNHox/PVP nanocomposite at the 1/2/1 ratio (w/w/w) had the best linearity. Moreover, the ternary mixture proved to have much better sensing properties compared to CNHox and CNHox-PVP-based sensing layers in terms of sensitivity and linearity. Each component of the ternary nanocomposites’ functional role is explained based on their physical and chemical properties. We analyzed the potential mechanism associated with the sensors’ response; among these, the effect of the p-type semiconductor behavior of CNHox and GO, correlated with swelling of the PVP, was dominant and led to increased resistance of the sensing layer.
