“…Due to possibilities for its use in room-temperature ionizing-radiation detectors, this material has deserved great attention of researchers since 1970s [1,2]. Lead iodide is also utilized in the solar cells based on both inorganic and organic-inorganic lead-halide perovskites, whose energy conversion efficiency exceeds 22% [3][4][5][6], as well as in photodetectors and some optoelectronic devices [7][8][9].…”
