Organic–inorganic hybrid perovskite is currently one of the most promising photovoltaic materials. In the present work, CH3NH3PbI3 nanowires were prepared by saturated vapor-assisted crystallization. The effects of annealing time on the size (width or height) and optical properties of CH3NH3PbI3 nanowires were systematically studied. It was found that the width of nanowires first decreases and then increases with the increase in annealing time. Moreover, as the size of the nanowires decreases, the absorbance increases, but the transmittance and the band gap decrease.
