Harnessing the N-dopant ratio in carbon quantum dots for enhancing the power conversion efficiency of solar cells

Abstract

Nowadays, green materials are being discovered to a greater extent to conserve the environment.

Fluorescence Quenching by Förster Resonance Energy Transfer in Carbon–Cadmium Sulfide Core-Shell Quantum Dots

“…Even after over one and a half decade of active research, the C QD keeps surprising the scientific community with its structure, properties, and an array of applications in various fields. In order to enhance the fluorescence (FL) and photon absorption properties, the C QD has been doped with materials like hydroxyapatite nanorods, nitrogen, and boron. − The C QD has also served as a shell for core semi-conducting nanoparticles such as CdS for various applications such as photocatalysis, photoelectrochemical water splitting, and solar cells. − The fluorescence quenching mechanism of C QD has also been reported with various nitroaromatic compounds such as 2,4,6-trinitrophenol, 2,4-dinitrophenol, p -nitrotoluene, nitrobenzene, etc …”

A review on advancements in carbon quantum dots and their application in photovoltaics

“…They further noted that the PCE (0.25% nitrogen-doped CQDs) was almost doubled (PCE 1.20%) under a low light intensity of 0.1 sun illumination (AM 1.5). 139 In 2020, Qiming Yang et al synthesized N-CQDs using hydrothermal methods for different durations (0.5, 1, 2, 4, 8, 16 hours) as shown in Fig. 20(a).…”

Real-time photovoltaic parameters assessment of carbon quantum dots showing strong blue emission

“…The resultant increase in efficiency is also ∼2.5 times. 35 In all cases, the current at 0 V was noted to be less than that at higher potential values. This makes the characteristics show lower FF and relatively high maximum current than its J sc .…”
