Synthesis of copper sulfide/reduced graphene oxide nanocomposites for use as the counter electrodes of high-performance CdS-sensitized solar cells

Highly catalytic reduced graphene oxide decorated Cu2S counter electrode boosting quantum dot–sensitized solar cell performance

“…Therefore, the current density increases in the presence of the graphene oxide lattice. The results also agree well with that of [14,35,47] (see table 2). Thang et al improved the current density of rGO@Cu 2 S to a higher level than those of Cu 2 S, CuS, and PbS electrodes; Radich et al [35] raised the current [22].…”

Synthesis and electrochemical performance of α-Al2O3 and M-Al2O4 spinel nanocomposites in hybrid quantum dot-sensitized solar cells

“…Either method requires specialized accommodation and has a respectable cost, while further disadvantages include the shortage of homogeneity and low surface area of product 5 – 10 , 16 – 18 , 31 – 33 . The generation of the homogeneous high-purity nanoparticles has been demonstrated by the sol–gel auto combustion technique with swift heating and short reaction time 11 , 12 , 34 . The sol–gel auto combustion synthesis method combines chemical sol–gel and combustion processes, representing a swift, attainable technique with low energy costs, and is perfect for the synthesis of materials based on metal oxides.…”

“…The sol–gel auto combustion synthesis method combines chemical sol–gel and combustion processes, representing a swift, attainable technique with low energy costs, and is perfect for the synthesis of materials based on metal oxides. Several organic compounds can be utilized as the fuel, but these have been imitatively fixed to citric acid, urea, glycine, and tartaric acid 7 , 12 . Graphene is an intriguing material with a novel two-dimensional skeleton composed of a single monomolecular layer of sp 2 -hybridized carbon atoms 1 , 4 .…”
