Abstract
This paper reports plasmonenhanced light transmission through the Ag nanoparticlecoupled graphene thinfilm deposited on fluorinedoped tin oxide FTO glass substrates An experimental setup is developed to quantify the photon enhancement due to metal nanoparticleembedded graphene layer The results show that a specific distribution of graphene nanosheets over Ag nanoparticledeposited FTO glass can trap maximum normally incident light for photovoltaic applications An enhancement of 635 in the current density of silicon solar cell kept under Agcoated FTO glass is observed for 30μL graphene dispersion deposited on the FTO/Ag 3 nm The results indicate the possibility of minimizing the reflection of incident radiation by combining plasmonic oscillations of metal nanoparticles with graphene plasmonics which can be useful for optoelectronic devices radiation sensors and various types of photovoltaic cells
