Abstract : The surface modification of CsPbBr3 perovskite provides an effective way of defect passivation for device applications. In this work, Camphor sulfonic acid (CSA) was used to modify the surface of CsPbBr3 microcrystals (MCs) and helped in enhancement of Photoluminescence (PL) emission, photoresponse, and photodetectivity. We fabricated the perovskite FTO/c-TiO2/CsPbBr3-CSA/Carbon composite self-powered photodetector. The device exhibited higher photo responsivity and detectivity of 1.523 mA/W and 2.1454 × 109 Jones, respectively, under white light with excellent stability on high ON/OFF cycles.
