Comparative analysis of characterization techniques of GQDs-based photovoltaic applications: A review

Photoelectric Performance of Several Dithienoheterocycles Dyes and Nanocomposite of Dyes/Graphene Quantum Dots for DSSCs

“…The yellow region represents the hole density distribution, and the green region represents the electron density distribution. D CT is the charge transfer distance between the centroid of the electron/hole, [ 90 ] and the longer D CT proves a smaller charge density overlap; parameters t is calculated to reflect the degree of overlap between the density weakening area and density increment area; S r reflects the situation of overlap, an increased S r means that more holes and electrons will overlap, resulting in an inability to produce efficient charge separation. One can find that the HJL‐3@GQDs/TiO 2 with higher D CT (3.783 Å), t (−0.932 a.u.…”

Recent advancement in quantum dot-based materials for energy storage applications: a review

“…Electrochemical experiments were used to study the supercapacitive characteristics of GQDs. 80 The electrode built of GQDs has a specific capacitance (SC) of 257 F g −1 at a current density of 3 A g −1 and a capacitance retention of 96% after 3000 cycles. A flexible symmetric supercapacitor (SSC) device was created using a simple fabrication approach with GQDs as the active material.…”
