Abstract

We demonstrate a PMMA reverse transfer method, where a PMMA/graphene bilayer was reversely transferred onto target substrates, to better control both contamination and crack formation relative to conventional approaches. Based on this novel transfer process, the graphene sheet resistance was greatly reduced by about 50% at the same transmittance, exhibiting ∼200% higher efficiency when applied in a solar cell as the anode.
