Abstract

A facile method to synthesize a CH ₃ NH ₃ PbI ₃ : MoS ₂ nanohybrid for high-performance solution-processed photodetectors is presented. The interfacial charge carriers transfer due to the existence of heterojunctions between the 2D MoS ₂ nanosheet and perovskite cuboids are utilized to enhance the device performance. The dark current of the photodiode Au/CH ₃ NH ₃ PbI ₃ : MoS ₂ /Au was suppressed and its photocurrent was enhanced when compared to a pristine perovskite nanocrystal device Au/CH ₃ NH ₃ PbI ₃ /Au. The lowest dark current of 0.34 × 10 ^-9 A was observed from the photodiode Au/CH ₃ NH ₃ PbI ₃ : MoS ₂ /Au and the photoresponsivity and photosensitivity increased from 312 mA W ^-1 to 696 mA W ^-1 and from 9.02 to 87.47, respectively, showing an enhancement of 123.1% and 869.7%. Also, the rising time and falling time were reduced from 73 ms to 50 ms and 60 ms to 16 ms, respectively, when compared to those for the pristine perovskite nanocrystal-based photodiode Au/CH ₃ NH ₃ PbI ₃ /Au. Therefore, this method provides a simple and effective approach to synthesize 2D nanosheet blended organic-inorganic nanohybrids for application in optoelectronic devices.
