Abstract: Photoelectric characteristics of photodetectors of the type of a photoresistor based on microcrystalline films of the organometallic perovskite CH$_{3}$NH$_{3}$PbI$_{3}$ with gold and aluminum contacts have been studied. The maximum photosensitivity of the photodetectors was 30 A/W. The buildup and decay times of the photoconductivity were in the range from 2.6 to 25.5 $\mu$s.

Keywords: photodetectors, organometallic perovskites, photosensitivity, photoconductivity.
