Synthesis and Characterizations of CH3NH3PbI3 : ZnS Microrods for Optoelectronic Applications

“…e absorption coefficient edge is blue shifted with the rise of ZnS concentration in MAPI thin film. is phenomenon occurred because ZnS has a high absorption coefficient in the low wavelength range [15,46]. e values of α for pure MAPI at 400 nm and 750 nm are 7.7 × 10 4 cm −1 and 6.9 × 10 4 cm −1 , respectively.…”

“…Here, we report the synthesis of MAPI : ZnS MRs via a one-step spin-coating method. ZnS is also a potential material for OE applications with a high absorption coefficient [15], which has been used as ETL in PSCs, showing better photovoltaic performance with a PCE of 17.4% [16]. To our best knowledge, various OE properties of MAPI : ZnS material have never been studied before.…”

Effects of Biopolymer Surfactants on the Morphology and Optical Properties of Zinc Sulphide (ZnS) Nanocrystalline Thin Film

“…Meanwhile, all the thin films capped with biopolymer surfactants displayed stronger diffraction peak intensity, suggesting their higher degree of crystallinity. 22 The results obtained from the XRD analysis are summarised in Table 2. The average crystallite sizes of ZnS nanocrystalline thin films were calculated using the Debye-Scherrer equation and varied from 1.71 nm to 2.98 nm.…”

Substrate to Nozzle Distance Influence on the Properties of Zinc Oxide Films Formed with Chemical Spray Pyrolysis Technique

“…There are some factors that may influence the physical properties with chemical spray pyrolysis technique stage include the spray temperature, the spray rate, the spraying geometry and the distance between substrate and nozzle [1,2]. Substrate of glass was used to fabricate the film coating [3], which is known an essential droplet distance at spray technique. Though 20 (cm) substrate-nozzle distance is not a valid distance for a good crystalline and 30 (cm) substratenozzle distance is the best crystalline in this system.…”

“…In present work, thin films were influence by the substrate-to-nozzle distances at constant substrate temperature 370 °C and concentration of 0.1 M [1]. The structural of the two samples were detected with X-ray diffraction and also the optical properties were determined via a spectrophotometer [3,4]. In addition, morphology surface of zinc oxide thin films was studied by Scanning Tunneling Microscope (STM).…”
