Book Part Synchrotron-Based Techniques for Analysis of Perovskite Solar Cells(Wiley-Blackwell, 2021) Farooq, Umar; Phul, Ruby; Shabbir, Mohd; Arif, Rizwan; AkremaPerovskite solar cells (PSCs) have been proven as promising material, owing to their remarkable performance attained in the field of photovoltaic (PV) and optoelectronics. These materials possess direct band gaps, high absorption coefficient, low exciton binding energy, and long carrier diffusion lengths. However, the primary electronic structure, size and spatial distribution, and other significant properties of perovskite materials are not fully understood due to a lack of precise and high-spatiotemporal resolution characterization techniques. A synchrotron provides high-brilliance X-ray beams that can easily penetrate deeper into the matter to explore the material's properties at the atomic or molecular level within a short time. Herein, we discuss synchrotron techniques for determining the structure and properties of perovskite materials within the bulk, at the surfaces and the interfaces. This chapter is dedicated to providing the latest findings on developing synchrotron-based techniques tailored for PSC. The method of characterization is also discussed with sample preparation. Finally, we focused on the state-of-the-art strategies for gaining in-depth knowledge of mechanism enhancing the photovoltaic performance and providing decisive answers to the outstanding science problems in the perovskite field, pushing forward technological development. © 2022 Elsevier B.V., All rights reserved.Conference Object Citation - Scopus: 1Color Simulation and Demonstration of Perovskite Nanocrystal Filters for Wide Color Gamut Displays(Institute of Electrical and Electronics Engineers Inc., 2018-09) Genc, Sinan; Yazici, Ahmet F.; Beskazak, Emre; Uran, Can; Mutlugün, EvrenIn this study, we define spectral parameters of perovskite nanocrystals to improve LCD color gamut, replacing color filters (CFs) with perovskite based subpixels. The optimization of the CFs has been enhanced 15.8% (98.43% of Rec.2020) in simulation and 13.8% experimentally, with 97.37% color gamut coverage. © 2019 Elsevier B.V., All rights reserved.Conference Object Arrays of Multi-Color Emitting Cesium Lead Halide Perovskite Nanocrystals and Efficient White Light Generation by Tailored Anion Exchange Reactions and Electrohydrodynamic Jet Printing(Optica Publishing Group (Formerly OSA), 2018) Altıntas, Yemliha; Torun, Ilker; Yazici, Ahmet F.; Beskazak, Emre; Onses, Mustafa Serdar; Mutlugün, EvrenWe employ highly efficient and narrow band emitter Cesium-lead-halide perovskite nanocrystals, optimized by the anion exchange method, for efficient white light generation by patterning multiple lines of different colors via proposed electrohydrodynamic jet printing. © 2023 Elsevier B.V., All rights reserved.
