摘要: Abstract The photoconducting properties of graphene–cobalt phthalocyanine organic semiconductor photodiodes were investigated. GO doped cobalt (CoPc) thin films prepared with various graphene oxide (GO) contents. electrical the diodes analyzed by using current–voltage and capacitance/conductance–voltage measurements. reverse current increases increasing illumination intensity. transient photocurrent, photocapacitance, photoconductance measurements also capacitance conductance increase after illuminating returns to original value turning off illumination. Graphene–cobalt based on optoelectronic device exhibited both a photodiode photocapacitor behavior under solar light illuminaton.
