Substrate-assisted Transfer of Nanoparticles by Graphene on Metal-Organic Interfaces

Nanoparticles synthesized by reverse micelle templating cannot be formed directly on the top of active layer in organic and perovskite devices. In this work, we show a method of transferring the synthesized nanoparticles on top of an organic layer using a graphene based transfer printing technique. To confirm the successful transfer of nanoparticles, perovskite based methylammonium lead bromide (MAPBr) nanoparticles were used and their presence confirmed by Photoluminescence (PL).
