Abstract

The implication of annealing temperature on zinc oxide (ZnO) based perovskite, Methylammonium lead Bromide (CH3NH3PbBr3) using hydrothermal bathing and spin coating deposition methods was investigated; which is an advantageous thin film technique for deposition of large films at ambient or low temperature. The zinc oxide (ZnO) based perovskite, Methylammonium lead Bromide (CH3NH3PbBr3) were successfully deposited on the substrate (Glass slide) at a deposition time of 3 hours and were annealed at different temperatures of 100˚, 130˚, 160˚,190˚ and 200˚ degree Celsius respectively. The optical and morphological characterization of the zinc oxide nanoparticles and the perovskite material sequentially deposited on the substrate (Glass slides) annealed at different temperatures of 100˚, 130˚, 160˚, 190˚, 200˚ degree Celsius at deposition time of 3 hours were carried out using the UV – Visible Spectrophotometer and x- ray diffractometer respectively. It shows a transmittance between 1.42 a.u to 1.48 a.u of the thin film within the wavelength band of 350nm – 1500nm and a direct allowed band gap of 3.33 eV – 3.35 eV. UV- VIS spectroscopy revealed that the zinc oxide nanoparticles and the perovskite material sequentially deposited on the substrate (Glass slides) and annealed at temperatures of 130˚degree Celsius at deposition time of 3 hours has the highest efficiency because it absorbed readily at the least absorbance of 3.38 a.u and transmitted highly at a transmittance of 1.48 a.u within the visible region when compared to other annealing temperatures
