Multilayer graphene nanoelectrodes for optoelectronic devices was investigated. The high transparency of graphene layers plays the main role in the optoelectrical conversion. Due to the high transparent electrodes, almost all incident light propagates through the graphene layers resulting in an increase in the number of the generated carriers and photocurrent. The graphene electrodes exhibit more than one order of magnitude higher generated photocurrent compared to the photocurrent of metal electrodes and an on/off ratio of four orders of magnitude.
