“…Carbon has various electronically hybridized orbitals, such as sp , sp 2 , and sp 3 , which present diverse structural variability and modification possibilities for the main structure of nanomaterials. This enables the structural extension and derivation from zero-dimensional (0D) to multidimensional materials including, 0D fullerenes, carbon nano-onions (CNOs), carbon nanodiamonds (NDs), and carbon dots (CDs); unidimensional (1D) carbon nanotubes (CNTs), nanohorns, and nanofibers; and two-dimensional (2D) graphene and graphene oxides (GOs), three dimensional (3D) nanocrystalline diamond and porous carbon, etc. − Therefore, various outstanding properties, such as the mechanical capacity, thermal and chemical stability, radiation resistance, electrical insulation, electrical conductivity, surface interfacial properties, and optical properties, have been explored based on the rich structural diversity and modifiability. − To date, carbon nanomaterials (CNMs) have attracted considerable attention in multitudinous fields related to mechanicology, geology, energy, chemistry, biology, medicine, and environmental science. , …”

Advances in nanotechnology and nanomaterials have attracted considerable interest and play key roles in scientific innovations in diverse fields. In particular, increased attention has been focused on carbon-based nanomaterials exhibiting diverse extended structures and unique properties. Among these materials, zero-dimensional structures, including fullerenes, carbon nano-onions, carbon nanodiamonds, and carbon dots, possess excellent bioaffinities and superior fluorescence properties that make these structures suitable for application to environmental and biological sensing, imaging, and therapeutics. This review provides a systematic overview of the classification and structural properties, design principles and preparation methods, and optical properties and sensing applications of zero-dimensional carbon nanomaterials. Recent interesting breakthroughs in the sensitive and selective sensing and imaging of heavy metal pollutants, hazardous substances, and bioactive molecules as well as applications in information encryption, super-resolution and photoacoustic imaging, and phototherapy and nanomedicine delivery are the main focus of this review. Finally, future challenges and prospects of these materials are highlighted and envisaged. This review presents a comprehensive basis and directions for designing, developing, and applying fascinating fluorescent sensors fabricated based on zero-dimensional carbon nanomaterials for specific requirements in numerous research fields.

“…Graphene/n-Si Schottky junction solar cells (GSSC) have attracted attention as a promising solar cell technology because of their low-cost fabrication and high-power conversion efficiency (PCE) [1][2][3][4][5][6][7][8]. The PCE of GSSCs has increased rapidly from approximately 1.5% in 2010 to around 15% in 2015, using various strategies such as hole doping, silicon surface passivation, and anti-reflection coating [9][10][11][12][13][14][15][16][17][18].…”

We have demonstrated a simple and accurate method for characterizing the capacitance of Graphene/n-Si Schottky junction solar cells (GSSCs) which embed the metal-oxide-semiconductor (MOS) capacitor. We measured two types of GSSCs, one with thermal annealing treatments (w-a) and one without (wo-a). It was found that the wo-a GSSC exhibits a two-step feature in the phase versus forward bias voltage relationship, which may be attributed to the presence of polymethyl methacrylate residues. By considering the capacitance of the MOS capacitor (Cmos) and its standard deviation, we successfully obtained the capacitance of the Schottky junction (CSch), and evaluated meaningful built-in potentials (Schottky barrier heights) which are 0.51V (0.78eV) and 0.47V (0.75eV) for the w-a and wo-a GSSCs, respectively, by the Mott-Schottky analysis. We also briefly discuss the relationship between CSch and the Nyquist and Bode plots, finding that the RC time constant decreases due to the subtraction of Cmos.

“…Especially, carbon nanotubes (CNTs), featured with outstanding electronic, photonic, chemical, and physical characteristics, are widely used as charge collectors and carrier transporters in the PV field, such as planar HJSCs . In recent years, CNT-based HJSCs have been demonstrated with state-of-art progress, top-down engineering for high efficiency including optical property tuning, Fermi level tuning, morphological design, and interface engineering . Surprisingly, Si/CNT HJSCs with multifunctional hole transporters and back-joint design could reach the highest power conversion efficiency (PCE) of 22.02%, approaching the predicted value of ∼23% .…”

Carbon nanotubes (CNTs) have gained significant interest due to their potential in enhancing the performance and cost effectiveness of photovoltaic (PV) applications. This study demonstrates the efficacy of an optimal cell configuration for InGaP/GaAs/CNT/sulfonated poly(tetrafluoroethylene) (Nafion)/PEDOT:PSS heterojunction solar cells (HJSCs). This was achieved by adjusting the thickness of the CNT film and the Al 2 O 3 buffer layer. The facile one-step spin coating of the multifunctional Nafion/PEDOT:PSS (NP) layer on the GaAs/CNT surface contributes to hole transportation, surface passivation, and formation of antireflection and encapsulation, resulting in a high power conversion efficiency (PCE) of 14.2% with better stability over one month of light soaking. Moreover, the corresponding mechanisms of the reaction between the highly hydrophilic sulfonate group of insulating, chemically stable Nafion and PSS in PEDOT:PSS are demonstrated by analyzing the morphology, chemical component, and configuration and their photoelectric properties. This work is highly important for obtaining high-performance, cost-effective, and air-stable SCs for light-harvesting industrial development.
