Abstract

High-sensitivity and fast-response photodetectors (PDs) are vital part of optical wireless communication (OWC) system. In this work, we develop an organic-inorganic hybrid perovskite material (MAPbI₃) based p-i-n structured PD. By optimizing the precursor solution concertation, the PD showed a high responsivity of 0.98 A W^-1, a fast response timet_rise/t_fallof 12/12.5 μs, a specific detectivity of 2.62 × 10¹³Jones, and the f_-3dBof 24 kHz under the 532 nm laser and -0.2 V bias voltage. Furthermore, we designed an OWC system based on the prepared PD. With the baud rate of 19200 bps, the system exhibits a bit error rate less than 10^-6, and it can realize 9.63 m long-distance communication and quick transmission applications such as strings, texts, photos, and audios. Our work demonstrates the great application potential of perovskite PDs in the field of optical communication.
