The paper describes an approach to fabricate large area Graphene (Gr)/MoS2 on paper using simple, cost effective solution processed hydrothermal method. Gr was deposited on paper using dip coating method followed by hydrothermal growth of 2D MoS2 on Gr. Raman analysis confirmed the growth of few layer MoS2. IV characteristic of MoS2, MoS2/Gr revealed higher conductivity for Gr/MoS2. Under illumination 31.84 % and 55.33 % decrease in resistance was observed for MoS2 and Gr/MoS2 based devices respectively indicating that Gr/MoS2 based devices are more sensitive compared to MoS2. Successful fabrication of flexible paper based Gr/MoS2 photodetector is a step ahead in large area, low cost electronic applications. © 2017 IEEE.
