“…After this treatment, the electrical conductivity of the CNT yarn was 3500 S/cm, which was almost 200% greater than the conductivity of the neat CNT yarn [43]. Ni et al demonstrated another DSSC efficiency increase using functionalized SWCNTs decorated with CdSe/ZnS coreshell colloidal quantum dots incorporated into different copolymers [44]. The results showed that the use of quantum dots increased the efficiency of non-quantized solar cells by 30% [44].…”

Advancements in dye-sensitized solar cell (DSSC) technology are occurring at an everincreasing rate, as the development of novel carbon-based materials, the increasing research into new 3D surface morphologies and cell design, and the focus on the development of new sensitizers and electrolytes have allowed many new possibilities for DSSCs. Solar cells that are three-dimensionally structured offer significant advantages over traditional crystalline / semicrystalline panels in that they can convert incident photons that strike them at large incident angles, can be flexible / used in applications which require non-rigid materials, and can be substantially cheaper to produce than traditional panels, especially with the replacement of more expensive, traditional electrode materials by carbon materials in the working / counter electrode.The use of carefully selected and engineered sensitizers like quantum dots with these threedimensionally structured solar cells have seen them achieve ever-increasing power conversion efficiencies, and it's likely that they will soon rival traditional crystalline / semi-crystalline panels for both mass power generation and use in more niche applications such as flexible photovoltaic textile fibers. This review covers DSSCs constructed with several different materials, and the advantages and disadvantages of a variety of cell designs.

High areal capacitance of Fe₃O₄‐decorated carbon nanotubes for supercapacitor electrodes

et al. 2019

A conceptually new approach has been developed for the fabrication of magnetite (Fe 3 O 4 )-decorated carbon nanotubes (M-CNTs) for negative electrodes of electrochemical supercapacitors. M-CNTs were prepared by an ultrasonic-assisted chemical synthesis method, which involved dispersion of functionalized CNTs in water, Fe 3 O 4 formation on the CNTs surface, and particle extraction through liquid-liquid interface (PELLI). Palmitic acid was found to be an efficient new extractor for PELLI. The slurries produced after drying and redispersing M-CNTs and slurries obtained using PELLI were used for electrode fabrication. The electrodes prepared using PELLI showed superior performance due to reduced particle agglomeration. Testing results provided an insight into the influence of Fe 3 O 4 /CNTs mass ratio on the capacitance and capacitance retention at high charge-discharge rates. A capacitance of 5.82 F cm −2 (145.4 F g −1 ) was achieved in Na 2 SO 4 electrolyte using electrodes with high active mass of 40 mg cm −2 and ratio of active mass to current collector mass of 0.6. Good electrochemical performance was achieved at low impedance.The capacitance of the negative M-CNTs electrodes was comparable with capacitance of advanced positive MnO 2 -CNTs electrodes, which was beneficial for the fabrication of asymmetric devices. The asymmetric device has been fabricated, which showed promising performance in a voltage window of 1.6 V.

“…These kinds of QDs offer prospects of novel size-dependent optical and electrical properties that make them attractive candidates for photodetector [13], biosensor [14], light-emitting device [15], and solar cell [16]. However, because the small nanoparticles are usually powders and lack favorable bulk mechanical properties and processing characteristics, host materials need to be developed to impart these properties as those offered by a Electronic supplementary material The online version of this article (doi:10.1007/s10853-014-8421-y) contains supplementary material, which is available to authorized users.…”

Optically active substituted polyacetylene@ CdSe quantum dots (SPA@CdSe QDs) nanocomposites were fabricated by grafting helical SPA polymers onto the surface of semiconductor QDs through ester linkage. Optically active SPA polymer derived from chiral amino acids was copolymerized by a rhodium zwitterion catalyst and was evidently proved to adopt a predominately singlehanded helical conformation. The SPA@QDs nanocomposites were characterized by Fourier-transform infrared spectroscopy, X-ray photoelectron spectroscopy, X-ray diffraction, transmission electron microscopy, and thermogravimetric analysis. The results indicated that the organic SPA matrix exhibited an enhancement in thermal stability after the hybridization with CdSe QDs, while the blended QDs maintained their original crystalline structure during grafting. The infrared emissivity properties of the SPA@QDs nanocomposites at 8-14 lm were further investigated. The data demonstrated that the SPA@QDs-15 composite film possessed an infrared emissivity value of 0.501, which was much lower than pristine SPA and QDs. This might be attributed to the incorporation of optically active helical SPA and semiconductor QDs in a hybrid phase, which had great effect in enhancing their interfacial interactions.
