Ag nanowire coated reduced graphene oxide/n-silicon Schottky junction based solar cell

Sulfur/reduced graphite-oxide and dual-anion solid polymer-electrolyte integrated structure for high-loading practical all-solid-state lithium–sulfur battery

“…The intensity ratio of the D and G bands (I D /I G ) is typically used to measure the defect density of a carbon nanostructure. In this study, the S/rGO I D /I G ratio was 0.99, which exceeds previously reported values [50][51][52] . This higher ratio was ascribed to the enhanced structural distortion caused by the S doping within the graphene lattice.…”

“…The G band is attributed to the Raman-active E 2g mode and indicates the crystallinity of the carbon material 49,50 . The intensity ratio of the D and G bands (I D /I G ) is typically used to measure the defect density of a carbon nanostructure.…”

Reduced graphene oxide today

“…156 The role of RGO in fabrication of optoelectronic devices is actually much broader and it covers several types of solar energy devices. RGO is currently being used in the fabrication of organic, [158][159][160][161][162] perovskite, [163][164][165][166][167][168] silicon [169][170][171][172] or dye-sensitized solar cells. [173][174][175][176][177] In organic and perovskite solar cells RGO is utilized as a component material in fabrication of hole/electron transport layers (or even as a stabilizing agent 167 ) while in DSSCs [175][176][177] and quantum dot-sensitized solar cells (QDSSCs) 173,174 RGO is a composite material for realization of better counter electrodes.…”

Application of three-dimensional graphene in sound generation via thermoacoustics

“…An increased probability of Raman scattering would increase the quantity of reflected Raman signals, reducing the 2D to G peak ratio. The Raman spectrum of rGO sheets in the hybrid material revealed the presence of D peak and G peak at 1350 cm -1 and 1580 cm -1 respectively with the absence of the 2D peak at 2705 cm -1 , indicating the presence of rGO sheets [162][163][164][165][166][167].…”

“…Comparing the intensities of the D peak and G peak, the intensity of the D peak is 1.47 times that of the G peak ( 47). The D to G peak intensity ratio being more than 1 implies that GO had been successfully reduced to rGO [164] as intended.…”
