摘要

Organic-inorganic hybrid perovskite single crystals are regarded as the most overwhelming platform among various building blocks for fundamental study.Here, we synthesized a series of perovskite single crystals with mixed organic cations(APbI_3, A = CH_3NH_3~+, MA~+ or CH(NH_2)_2~+, FA~+) along the compositional space, and provided a systematical investigation to correlate the carrier behavior to the organic cations.The single crystals were synthesized via inverse temperature crystallization assisted by hydroiodic acid, where the quality of the crystals could be judiciously controlled by the thermodynamic process.It is found that the substitution of 15% MA~+ in the FAPbI_3 single crystals stabilizes the phase with the best charge transport characteristics.Both photodetector and J-V measurement suggested that FA_(0.85)MA_(0.15)PbI_3 single crystal exhibit suppressed ion migration than the counterpart of FA_(0.15)MA_(0.85)PbI_3 single crystal.These results represent an important step to highlight the role of organic cations in the hybrid perovskite materials, which will further benefit fundamental understanding of materials and device optimization.
