High Quality Hybrid Perovskite Semiconductor Thin Films with Remarkably Enhanced Luminescence and Defect Suppression via Quaternary Alkyl Ammonium Salt Based Treatment
Abstract
<jats:title>Abstract</jats:title><jats:p>Significant enhancement in the luminescence and superior photophysical properties of CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbBr<jats:sub>3</jats:sub> thin films prepared via simple single step spin coating process involving a novel additive mediated solvent extraction step is reported. This process results in significantly lower disorder in CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbBr<jats:sub>3</jats:sub> perovskites with Urbach energies reducing from ≈35 to ≈17 meV, which is the lowest reported value to date. The additive mediated process also results in a remarkable improvement in the photoluminescence quantum yields (PLQYs) from 1% to 30%. Coupled with the overall increase in surface roughness, a significant increase in the internal PLQY from 7% to 77% is estimated, indicating the superior quality of the treated thin films. The resultant high quality CH<jats:sub>3</jats:sub>NH<jats:sub>3</jats:sub>PbBr<jats:sub>3</jats:sub> perovskites with remarkable photophysical properties can be used in realizing highly efficient optoelectronic devices. Highly efficient light emitting diodes using these perovskites are demonstrated here.</jats:p>
