AbstractLead sulphide thin films have been successfully deposited by spin coating lead hexadecyl and octadecyl xanthate onto glass substrates and annealed at moderate temperatures. The thin films were characterized using powder x-ray diffractometer (p-XRD) and were found to be face centred cubic (FCC) with the (200) being the most preferred orientation. The optical band gaps obtained were 0.93 and 1.00 eV respectively for PbS from complexes (1) and (2) annealed at 350 °C. They were all blue shifted from the bulk value of 0.41 eV.

The Stability

AbstractAll inorganic lead-based perovskites containing bromine-iodine alloys, such as CsPbIBr2, have arisen as one of the most attractive candidates for absorber layers in solar cells. That said, there remains a large gap when it comes to film and crystal quality between the inorganic and hybrid perovskites. In this work, antisolvent engineering is employed as a simple and reproducible method for improving CsPbIBr2 thin films. We found that both the antisolvent used and the conditions under which it was applied have a measurable impact on both the quality and stability of the final product. We arrived at this conclusion by characterising the samples using scanning electron microscopy, X-ray diffraction, UV–visible and photoluminescence measurements, as well as employing a novel system to quantify stability. Our findings, and the application of our novel method for quantifying stability, demonstrate the ability to significantly enhance CsPbIBr2 samples, produced via a static one-step spin coating method, by applying isopropanol 10 s after commencing the spin programme. The antisolvent quenched CsPbIBr2 films demonstrate both improved crystallinity and an extended lifespan.
