Titan, the largest moon of Saturn, is surrounded by a permanent thick photochemically-produced haze made of solid organic particles. These nanometer-sized particles spend about one year in suspension, undergoing further physical evolution during their atmospheric journey towards Titan's surface. In the present work we have simulated in the laboratory the emission of photoelectrons by submitting Titan's aerosols analogues to realistic EUV radiations. The aerosols are found to be easily ionized producing photoelectrons close to Titan's surface.
