A series of Co/Alq3 granular films were deposited on silicon substrates using co-evaporation technique. Under the nonuniform illumination of a laser beam, lateral photovoltaic effect (LPE) was observed in the samples, with the optimal open-circuit position sensitivity of 34.7mV/mm. The insertion of oxide layer results in the decrease of lateral photovoltage (LPV) and the irreversible LPE. The dependence of lateral photovoltaic effect on substrates was also briefly investigated. The possible mechanism was discussed.
