Abstract
The use of photovoltaic (PV) cells for simultaneous energy harvesting and optical detection has remained largely unexplored mostly due to the inherent low bandwidth of PV cells. However, the development of new PV cells based on Perovskite has opened up a window of opportunity for the use of PV as a photodetector (PD) in certain applications. In this work, we investigate flexible Perovskite PV cells as a PD for use in optical wireless communication and characterize it in terms of spectral response, external and power conversion efficiencies, and bandwidth. The results show a maximum responsivity of 0.043 (A/W) at a wavelength of 495 nm, and bandwidth of ~24 and 70 KHz for the active areas of 4 and 0.49 mm 2 , respectively. We demonstrate that the perovskite PD is a promising candidate for energy harvesting and optical detection, thus paving the way for the development of wearable devices in many practical applications.
