Strontium Insertion in Methylammonium Lead Iodide
Abstract
<p>The partial replacement of Pb<sup>2+</sup> by Sr<sup>2+</sup> in MAPbI<sub>3</sub> was investigated and its effect on the morphological, optical, and electronic behavior of the material was studied. Glass substrates with a pre-patterned indium tin oxide coating were cleaned with a detergent solution, Millipore water, and isopropanol with 5 min of sonication for each step and finally transferred to a UV?O<sub>3</sub> chamber for 20 min. Afterward, an 80 nm thick PEDOT:PSS film was spin-coated in air at 3000 rpm for 50 s and annealed at 150°C for 15 min. Then, the substrates were transferred to an N<sub>2</sub>-filled glovebox and the PEDOT:PSS was annealed again at 120°C for 10 min during the preparation of the perovskite precursor solution. The solution was spin-coated at 1750 rpm for 2 min and the resulting layers were annealed at 85°C for 25 min. No anti-solvent dripping or particular treatment has been employed for the perovskite thin film deposition. The long charge carrier lifetimes, as observed by TRMC, corroborate the effect of the Sr<sup>2+</sup> insertion on the charge extraction efficiency. The origin of these effects is, however, not completely clear. We have shown effects on the crystal size and surface properties such as decreased crystal dimensions and roughness, surface Sr<sup>2+</sup> enrichment, and also an increase in the perovskite work function upon Sr<sup>2+</sup> incorporation in the perovskite film.</p>
