The paper presents an analysis of the experiments on current rise and fall kinetics under the influence of hard ultraviolet radiation on the indium-zinc oxide fibrous layer obtained by electrospinning. It is shown that the photocurrent increase rate can be varied by the radiation intensity, and its decrease – by the oxygen partial pressure on the nanofibers’ surface. The proposed UV sensor with a layer of nanoscale fibers possesses a higher response rate as compared to that of homogeneous film structures due to the significantly larger area of the active surface, where the centers of oxygen adsorption are concentrated.
