“…As an example, we used the PMMA/rosin-transferred monolayer graphene as an anode in flexible OPV cells (Figure a) with an active area of 0.2 cm 2 , which is larger than most of the relevant devices reported in the literature (Figure S12 and Table S2). ,− For comparison, we also fabricated and tested OPV cells under the same conditions, and of the same size and structure using a PMMA-transferred monolayer graphene film on PET or commercial ITO on glass as the anode. The cell made with PMMA/rosin-transferred graphene anode showed a higher short circuit current ( J SC ≈ 12.1 mA cm –2 ), open circuit voltage ( V OC ≈ 0.87 V) and fill factor (FF ≈ 54%) than those made with the PMMA-transferred graphene anode (Figure b,c and Table ).…”

Clean transfer of two-dimensional (2D) materials grown by chemical vapor deposition is critical for their application in electronics and optoelectronics. Although rosin can be used as a support layer for the clean transfer of graphene grown on Cu, it has not been usable for the transfer of 2D materials grown on noble metals or for large-area transfer. Here, we report a poly(methyl methacrylate) (PMMA)/rosin double support layer that enables facile ultraclean transfer of large-area 2D materials grown on different metals. The bottom rosin layer ensures clean transfer, whereas the top PMMA layer not only screens the rosin from the transfer conditions but also improves the strength of the transfer layer to make the transfer easier and more robust. We demonstrate the transfer of monolayer WSe2 and WS2 single crystals grown on Au as well as large-area graphene films grown on Cu. As a result of the clean surface, the transferred WSe2 retains the intrinsic optical properties of the as-grown sample. Moreover, it does not require annealing to form good ohmic contacts with metal electrodes, enabling high-performance field effect transistors with mobility and ON/OFF ratio ∼10 times higher than those made by PMMA-transferred WSe2. The ultraclean graphene film is found to be a good anode for flexible organic photovoltaic cells with a high power conversion efficiency of ∼6.4% achieved.

“…In 2015, Moaven et al reported the synthesis of an rGO/Ag nanocomposite electrode appropriate for OSCs [48]. The reported technique is applicable to flexible substrates by spin coating of an aqueous solution of rGO/Ag nanocomposite on polyethylene terephthalate (PET) substrate in ambient conditions.…”

The isolation of free-standing graphene in 2004 was the spark for a new scientific revolution in the field of optoelectronics. Due to its extraordinary optoelectronic and mechanical properties, graphene is the next wonder material that could act as an ideal low-cost alternative material for the effective replacement of the expensive conventional materials used in organic optoelectronic applications. Indeed, the enhanced electrical conductivity of graphene combined with its high transparency in visible and near-infrared spectra, enabled graphene to be an ideal low-cost indium tin oxide (ITO) alternative in organic solar cells (OSCs). The prospects and future research trend in graphenebased TCE are also discussed. On the other hand, solution-processed graphene combines the unique optoelectrical properties of graphene with large area deposition and flexible substrates making it compatible with printing and coating technologies, such as roll-to-roll, inkjet, gravure, and flexographic printing manufacturing methods.

“…Their applications in Dye Sensitized Solar Cells (DSSC) (Bella et al, 2015), energy storage and conversion (Griffini et al, 2014(Griffini et al, , 2013 have been reported recently. Encapsulation technology is widely used for various SPV technologies and systems such as Solar Thermoelectric (Sundarraj et al, 2014), silicon carbide (SiC) based SPV cells (Cheng et al, 2015), flexible polymer SPV cells (Moaven et al, 2015). Polymeric materials are most commonly used for encapsulation of c-Si SPV modules.…”
