Abstract

Contrarily to conventional methylammonium lead iodide of CH3NH3PbI3, a novel derived 2D hybrid perovskite C6H8N2PbI3 was alternatively produced by reflux method under ambient air condition. In this work, the effect of different ratios of 45% N, N-dimethylformamide (DMF) in reaction of dilution with 1 g hybrid perovskite C6H8N2PbI3 crystals was successfully prepared. Simple solar cells were fabricated by spin-coating method of deposition titanium dioxide (TiO2) layer and liquid-precursor of various 45% DMF ratios onto ITO substrates. The chemical bonding consists of ammonium (NH3+), pyridinium (C5H6N+) and Ar-H ions in both solid and liquid compounds confirmed by FTIR analysis. A bulk conductivities detected by electrochemical impedance spectroscopy (EIS) within the range of 10 MHz to 100 kHz and show that the conductivity values are in between the range of 5.073 × 10−6 and 1.587 × 10−5 S cm−1 which is classified as semiconductor materials. The stability of the solar cell to produce VDC(max) value of 0.55 ± 0.06 V under sunlight irradiance was systematically retrieved over 30 days. Overall, the sustainability and performance of the cells meet the requirements of light-sensitizer material in future PSCs.
