“…The usage of NCQDs as a co-photoactive layer resulted in a high photoconversion efficiency of 8.75% and a photocurrent density of 18.13 mA/cm 2 under one solar irradiation. As a co-sensitizer and sensitizer, the achieved power conversion efficiency was from 55% to 99%, which was better than NCQDs (Shejale et al, 2021). This method produced CQDs with good physiochemical and optical features, including wide spectrum absorption, high charge carrier extraction, rapid charge carrier transportation, and tunable emission.…”

Fluorescent carbon nanoparticles also termed as carbon quantum dots (CQDs) have attracted so much interest when compared to the traditional semiconductor quantum dots due to their applications in chemical sensing, biomedical imaging, nanotechnology, photovoltaics, light-emitting diodes (LEDs), and electrochemistry. Along with their optical features, CQDs have desired properties such as less toxicity, environmentally friendly nature, inexpensive, and simple preparation processes. In addition, CQDs can have their physical and chemical properties controlled by surface passivation and functionalization. This article provides an account of CQDs because of their distinct characteristics and considerable capacity in diverse applications. The article is categorized into various sections that highlight various synthesis methodologies of CQDs with their advantages/disadvantages and their potential applications in sensors, bio-imaging, drug delivery, solar cells, and supercapacitors. The different applications of CQDs can be demonstrated by controlled synthesis methods. We have also discussed gas sensing applications of CQDs briefly and provided a brief overview of osmotic power generation using CQDs for energy applications.

“…28 Moreover, CDs can be integrated in the photoactive layer in solar cells, which synergically enhance the photo-absorbance and reduce the recombination process, demonstrating the potential application of CDs in energy harvesting devices. 255 Far beyond the above promising applications, CDs alone or combined with various materials ( e.g. , noble metals, 256 metal oxides, 257 and carbon nitrides) have been extensively explored in photocatalysis 258 and electrocatalysis, 259 nanoenzymes, 260 and machine learning.…”
