Non-stoichiometric Cu–In–S@ZnS nanoparticles produced in aqueous solutions as light harvesters for liquid-junction photoelectrochemical solar cells

“…The In3d section exhibits a doublet at 444.1/451.7 eV with a splitting of 7.6 eV characteristic for In(III). 12,28,36,37 The peak positions are typical for trivalent indium in ternary copper-indium chalcogenides. 33,34 The Cu2p section of the XPS spectrum reveals a doublet at 931.4/951.3 eV (Fig.…”

Advances in Subcritical Hydro‐/Solvothermal Processing of Graphene Materials

“…Other complex oxides which have high electrochemical activity such as Li 4 Ti 5 O 12 , NiMoO 4 , CdFe 2 O 4 , and CuFe 2 O 4 were also coupled with graphene through solvothermal crystallization route. Similarly metal oxide semiconductors such as Co 3 O 4 , MoO 3 SnO 2 , MnO 2 , Mn 3 O 4 , VO 2 , RuO 2 , Fe 3 O 4 , Cu 2 O, Bi 2 O 3 , Cr 2 O 3 , and WO 3 , V 2 O 5 , metal sulfides such as ZnS, NiS, CuS, CdS, Ni 3 S 2 , MoS 2 , VS 2 ,Ce doped SnS 2 , CuInS 2 , and Co 9 S 8 , metal nanoparticles such as Ni, were successfully integrated into graphene through solvothermal routes. The combination of metal oxide or metal sulfides with graphene resulted in the excellent capacitance activity and long cycling stability of the resultant composites.…”

“…The GQDs‐PEG spin‐coated onto an ITO substrate showed higher photon‐to‐electron conversion capability compared with GQDs on ITO and was considered as a good dopant material for solar cells. Recently CuInS 2 ‐QDs hybridized with graphene through solvothermal route applied for poly(1‐methoxy‐4‐(2‐ethylhexyloxy)‐p‐phenylenevinylene) based solar cell exhibited an efficiency of 1.5% …”

Graphene-based materials for polymer solar cells

“…However, the fullerene materials are limited by low-efficient hopping charge transport of their spherical structures, leading to the obstruction of charge transport, and high-cost undesirable for large-scale fabrication [62]. As an allotrope of fullerenes, graphene has been regarded as a good candidate to replace fullerenes and its derivatives as excellent acceptor materials owing to its high carrier mobility and unique two-dimensional structure, beneficial for the collection and transport of charge carriers [63,64]. Furthermore, theoretical studies have predicted that the PCE of single junction and tandem PSCs using graphene-based materials as acceptors could even achieve 12 % and 24 %, respectively [24].…”
