A fragrance generator comprises a housing for containing a volatile liquid to provide a vapour. The housing has a wall of which at least a part is permeable to the vapour. The generator further comprises an actuator for diffusing the vapour emerging from the volatile liquid to an environment outside the housing. The generator is provided with an electric circuit comprising a solar energy converter arranged to convert solar energy into electric energy for feeding the actuator and the circuit comprises a capacitor for accumulating the electric energy from the solar energy converter.
