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.Book Part Citation - Scopus: 2Paper-Based Substrates for Sustainable (OPTO)Electronic Devices(Elsevier, 2022) Usta, Hakan; Facchetti, A. F.Cellulose-based paper has been a convenient eco-friendly platform for storing and exchanging information for thousands of years. Amazingly, the studies and advancements in the past decade have demonstrated that paper and nanocellulose-based substrates are also attractive for fabricating flexible electronic circuits as well as optoelectronic components and devices. Paper and nanocellulose-based substrates have been considered for use in new generation green devices and optoelectronic applications based on their sustainable and inexpensive source, lightweight, and superior mechanical/optical properties, all factors that could also reduce manufacturing costs for producing these devices. In this chapter, we review functional materials and optoelectronic devices fabricated on paper or nanocellulose-based substrates including transistors and circuits, solar cells, light-emitting diodes, and other devices, such as sensors/actuators, batteries, supercapacitors/energy-harvesters, and breathalyzer/diagnosis devices. We also thoroughly discuss remaining challenges and promising research directions with paper-based substrates for future advancements in green optoelectronics. © 2022 Elsevier B.V., All rights reserved.
