Fabrication of Perovskite Nanowire Photodetectors by Solution Process
Abstract:As an excellent light absorption semiconductor material, organic-inorganic hybrid halide perovskite has been widely used in the field of optoelectronics. To fabricate high performance photoelectric detection devices, a highly ordered ultra-long CH3NH3PbI3 nanowire is prepared by solution process and is used to fabricate an Au/CH3NH3PbI3/Au planar photoelectric detector. The device has a wide operation waveband. It has light response in the spectral range from ultraviolet to near-infrared (365-808 nm). Its maximum light responsibility (R), detectivity (D*), Ilight-Idark ratio and light response time are up to 3.81 A·W-1, 3.7×1011 Jones, 4.9×103 and 7 ms respectively. Because of excellent light detection ability, the device has a wide application prospect.
