In the past few years, organic-inorganic hybrid perovskites have received great attention for its use in solar cell and other opto-electrical devices. Most of these devices are based on perovskite thin films. Perovskite thin films, however, have higher trap density and grain boundaries that remain many questions in terms of their fundamental and intrinsic properties. On the other hands, macroscopic single crystal can be an ideal platform for understanding these intrinsic properties. Recently, facile and rapid growth of organic-inorganic hybrid perovskite single crystals through inverse temperature crystallization(ITC) process has been reported. In this work, we report the growth of CH3NH3PbBr3 single crystals with its electrical characterization for better understanding their fundamental and intrinsic properties that is necessary for opto-electronic devices based on organic-inorganic perovskites. |
