Tetrabutylammonium (TBA)-Doped Methylammonium Lead Iodide: High Quality and Stable Perovskite Thin Films
Abstract
<jats:p>This work reported the successive incorporation of tetrabutylammonium (TBA) into Methylammonium lead Iodide (MAPbI<jats:sub>3</jats:sub>) perovskite. The thin films were characterized by X-Ray diffraction (XRD), Scanning electron microscopy (SEM), Transmittance electron microscopy (TEM), Atomic force microscopy (AFM), and UV-Visible spectroscopy. It was shown that introducing TBA increases the crystallinity, grain size, surface morphology without pin-hole, and roughness of the MAPbI<jats:sub>3</jats:sub> thin films. Moreover, the MA<jats:sub>(1-X)</jats:sub>TBA<jats:sub>X</jats:sub> PbI<jats:sub>3</jats:sub> thin film shows better stability in a relative humidity of ∼60% after 15 days than the pure MAPbI<jats:sub>3</jats:sub> thin film. The obtained results are hoped to be helpful for stability and improvement of the performance of the MAPbI<jats:sub>3</jats:sub> thin films by doping TBA cations under ambient conditions.</jats:p>
