In this study, we investigated the light induced electrical properties of MoS2 field effect transistor after phthalocyanine molecule adsorption. The enhancements of the photo current by CoPc adsorption are 3,6.5 and 9.5 times at 660nm for the thickness of 2,10 and 20 angstrom respectively. Other phthalocyanine molecules also exhibited photo enhancement properties with light.
