      Dye-Sensitized Solar Cells.

AB  - A scalable and low-cost production of graphene nanoplatelets (GnPs) is one of the 
      most important challenges for their commercialization. A simple mechanochemical 
      reaction has been developed and applied to prepare various edge-functionalized 
      GnPs (EFGnPs). EFGnPs can be produced in a simple and ecofriendly manner by ball 
      milling of graphite with target substances (X = nonmetals, halogens, semimetals, 
      or metalloids). The unique feature of this method is its use of kinetic energy, 
      which can generate active carbon species by unzipping of graphitic CC bonds in 
      dry conditions (no solvent). The active carbon species efficiently pick up X 
      substance(s), leading to the formation of graphitic CX bonds along the broken 
      edges and the delamination of graphitic layers into EFGnPs. Unlike graphene oxide 
      (GO) and reduced GO (rGO), the preparation of EFGnPs does not involve toxic 
      chemicals, such as corrosive acids and toxic reducing agents. Furthermore, the 
      prepared EFGnPs preserve high crystallinity in the basal area due to their 
      edge-selective functionalization. Considering the available edge X groups that 
      can be selectively employed, the potential applications of EFGnPs are unlimited. 
      In this context, the synthesis, characterizations, and applications of EFGnPs, 
      specifically, as metal-free carbon-based electrocatalysts for dye-sensitized 
      solar cells (DSSCs) in both cobalt and iodine electrolytes are reviewed.
