Abstract
Perovskite based self-powered photodetectors can be used for future VLC networks employing low-power transmitters and large number of photodetectors to make use of the modern receiver diversity techniques. This paper presents a methylammonium lead bromide (MAPbBr3) based photodetector which can provide high responsivity and detectivity. Composition engineering is performed by using a TiS3 electron transport layer (ETL) and numerically evaluating the performance by varying the absorber layer thickness. Simulation results show an improved performance as compared to the recently reported designs, with responsivity of 0.625 A/W and detectivity of 1.7×1013 Jones at 800 nm wavelength for 1 μm perovskite absorber layer. Thus the proposed perovskite based photodetector can be used for modern energy efficient VLC applications.
