Abstract: A highly conductive and transparent graphene film is deployed as an efficient intermediate layer (IML) in tandem organic photovoltaic cells. Tandem cells utilizing transition metal oxide modified graphene IML demonstrate a high open circuit voltage (V oc) of 1.13 V in series connection. The value of V oc from tandem cell is very close to the sum of V oc attained from two individual subcells (0.58 V) that confirms the perfect ohmic contact at the photoactive layer/graphene interface. The UPS result showed the work function of graphene can be increased effectively to ensure good charge collection with different thickness of MoO 3 layer. © 2011 IEEE.
