Optical and electrical properties of perovskite microrods

Abstract Organic‐inorganic perovskites have become widely studied materials for their superior optoelectronic applications. This research reports the synthesis of CH 3 NH 3 PbI 3 perovskite microrods via one‐step deposition for optoelectronic applications. Crystalline and morphological structure, bond information, optical, and electrical characteristics have been studied. The perovskite microrods showed fine crystalinity with 90 nm–300 nm rod diameter with a high absorption coefficient over 10 4 cm −1 . A very lesser refractive index (1.85–2.00) was observed in the visible region. A comparison among different bandgap measuring techniques has also been demonstrated and up to 5.5 % deviation in measured bandgap was observed.
