Abstract

In this work, a novel 2D hybrid perovskite of C6H8N2PbBr3 was alternatively produced by reflux method under ambient air condition. The produced material was systematically characterized as potential light-harvesting material for perovskite solar cells (PSCs). The optical energy band measured using UV–Vis was 2.57 eV. The existence of NH3 +, pyridinium and Ar-H ions in the produced sample was confirmed by FTIR analysis. Bulk conductivity of the hybrid perovskite sandwiched with TiO2 layer measured by electrochemical impedance spectroscopy was 5.79 × 10−8 S cm−1. The sandwiched sample produced VDC(max) value of 0.65 V under sunlight irradiance. The value sustained over 720 h with ±0.07 V. Overall, the performance of the produced novel 2D hybrid meets the requirements as a light-harvesting material.
