Electrophoretic graphene for transparent counter electrodes in dye-sensitised solar cells

Electrophoretic deposition of graphene-related materials: A review of the fundamentals

“…However, high concentrations of these ions can destabilize the suspensions, whilst, their electrophoresis and accumulation on the electrode's surface can have negative effects on the deposition of the desired GRM [90] as described in Section 5. iv. Typical metal salts that are used for charging GRM for EPD are nitrates of aluminium [91][92][93][94], nickel [95][96][97], zinc [98], cobalt [99], manganese [63,100], magnesium [17,20,31,39,68,85,86,[101][102][103][104][105][106][107][108] and magnesium chloride [109], although, copper sulfate has been used recently [110]. The performance of these ions, however, may be pH dependent.…”

Graphene-based cathodes for liquid-junction dye sensitized solar cells: Electrocatalytic and mass transport effects

“…The catalytic activity of FGS correlated with the amount of oxygen in carbonaceous skeleton, until certain limit, when the electrical conductivity became performance-controlling [63]. The studies of various other graphene cathodes for I-mediated DSCs confirmed that performance comparable to Pt is hard to achieve [60,81,101,[116][117][118][119][120][121][122][123][124][125] particularly if optical transparency is also M a n u s c r i p t 13 requested (for review see Refs. [101,114]).…”

Application of graphene-based nanostructures in dye-sensitized solar cells

“…There are only few reports on optically transparent graphene‐based cathodes . A systematic work was carried out with GNP deposited on FTO .…”

“…Besides pure graphene, also composites of graphene with conducting polymers were successfully tested to the same purpose . In general, however, a performance comparable to that of Pt@FTO is hard to achieve in graphene‐based electrodes and I‐mediated systems, particularly if optical transparency of the cathode is required (for review see Ref. ).…”
