Outstanding Room-Temperature Hydrogen Gas Detection by Plasma-Assisted and Graphene-Functionalized Core–Shell Assembly of SnO2 Nanoburflower

“…Degree of strain induced in the particle due to the size reduction has been estimated from the slope of the strain graphs (elaborated in SI). 16 Some physical properties of the synthesized SnO 2 nanoparticles (NP) derived from X-ray diffractogram are shown in Table 1.…”

Performance Enhancement of Solar Cell by Incorporating Bilayer RGO‐ITO Smart Conducting Antireflection Coating

“…ITO_80 and other respective RGO coated ITO_80 glass substrates, viz., ITO_80_RGO15_glass (RGO with 15 µgm mL −1 density coated on 80 nm thick ITO), ITO_80_RGO25_glass (RGO with 25 µgm mL −1 density coated on 80 nm thick ITO), and ITO_80_RGO35_glass (RGO with 35 µgm mL −1 density coated on 80 nm thick ITO) have been prepared to compare the transmission spectra within the regime of 300–1100 nm. The calculated integrated transmission fraction (Equation S5, Supporting Information) of ITO_80_glass is 0.8939, which has been considered as the reference substrates to perceive the benefit of RGO of different thickness on ITO_80 ( Figure ).…”

“…Photons are absorbed in the RGO layer as light travels greater path through the RGO with the increment of thickness of RGO at the cost of reduction in effective transmittance. The absorbed photon fraction increases from 7.07 × 10 −4 to 8.56 × 10 −4 with the increment of the density of the RGO colloid from 15 to 35 µgm mL −1 (Equation S4, Supporting Information), tabulated in Table .…”

“…In order to quantify the reflection benefit due to incorporation of RGO (various thicknesses) on optimized ITO layer (80nm) with textured wafer as base, has been compared with ITO_80 on text wafer, shown in Figure . Respective reflected photon count and the integrated photon fraction have been calculated (Equation S3, Supporting Information) and tabulated in Table .…”

“…Reduction of reflection with the increment of the RGO layer thickness does not at all infer that higher number of photons were harvested, as the corresponding transmittance graph (Figure ) reflects a significant loss caused due to more absorption, supported by the absorption graph (Figure ). In order to calculate the exact photon fraction injected to the solar cell, we have incorporate the entire reflected, transmitted, and absorbed photon fraction under consideration (Equation S6, Supporting Information) . It is observed from Table that the best injected photon fraction can be achieved through ITO_80_RGO25, which is 0.8705.…”
