TL;DR: The present findings indicate that controlling organic-graphene heterointerface could provide a design strategy of organic solar cell architecture for boosting photon harvesting and show a 5 times increment in the maximum power conversion efficiency than the equivalent devices without a graphene layer.

TL;DR: A polymeric bilayer (PMMA/PBU) is coated on graphene as a supporting layer for the water-free transfer process and as an excellent passivation layer that enhances device operation.

TL;DR: In this paper, a simple and broadly applicable transfer method is developed using an organic liquid with a low surface tension to uniformly transfer high-quality graphene onto arbitrary substrates, even onto superhydrophobic substrate.

TL;DR: The thermal response of the conductance could be utilized to maintain a certain degree of p-doping of monolayer graphene, which provides the facile, sustainable, and controllable large-area doping method of graphene for future generation of printed flexible electronics.

TL;DR: The combination of a clean graphene surface and a suitable underlying substrate could serve as an atomically thin growth template to engineer the interaction between organic molecules and aromatic graphene network, thereby paving the way for effectively and conveniently tuning the semiconductor layer morphologies in devices prepared using graphene.
