Carbon Assisted Methylammonium Lead Iodide Microcrystalline Device for an Inexpensive Self-Powered Photodetector

Organometallic halide perovskite as Methyl Ammonium Lead iodide (MAPbI(3)) is the basis of current focus of solar energy materials research. Here we report acetophenone assisted pure phase MAPbI(3) powder crystals synthesis for fabrication of inexpensive self-powered photodetector. The as fabricated photodetector ascertain, response time of 200 ms with detectivity similar to 8.2 x 10(11) jones at zero bias voltage and the SNR similar to 4 x 10(3) under white light illumination intensity (19 mW/cm(2)). Wt% variation of MAPbI(3) reveals that 20 wt% of the perovskite crystals in carbon matrix is better candidate for a compatible photodetector. (C) 2019 Elsevier B.V. All rights reserved.
