    (Elsevier B.V., 15 July 2025) Aftab, Sikandar; Goud, Burragoni Sravanthi; Ali, Zeeshan; Assiri, Mohammed A.; Kim, Jae Hong; Akman, Erdi
    To date, the advancement of clean and sustainable energy sources has been a primary focus of research, addressing the global increase in energy consumption and related environmental issues. The swift progress of nanomaterials in solar energy conversion has generated significant interest owing to their exceptional structural and optoelectronic characteristics. This review paper examines the cutting-edge innovations and practical implementations of nanomaterials such as nanoparticles, quantum dots, nanorods, nanospheres, nanoflowers, nanocomposites, nanotubes, and one-dimensional (1D) and two-dimensional (2D) materials in the development of next-generation solar cells. We examine the incorporation of mentioned nanomaterials as absorber layers, doping agents, and modification agents in several solar cell designs. These materials are perfect for increasing the scalability and efficiency of solar energy conversion systems because of their special qualities, which include enhanced charge carrier dynamics and tunable bandgaps. We address critical issues like scalability, cost, and environmental concerns while discussing their contributions to improving light absorption, charge separation, and device stability. Moreover, this review clarifies the new device architectures utilizing nanomaterials as absorber layers, revealing the complex mechanisms that contribute to their enhanced performance and realistic stability behaviors. In order to overcome obstacles and fully utilize the potential of nanomaterials for sustainable energy solutions, we conclude by outlining future directions with a focus on interdisciplinary approaches. Interdisciplinary collaboration and ongoing refinement can fully realize the potential of new kinds of nanomaterials, offering significant solutions to global energy concerns and advancing scientific advancement in this emerging sector.

    (Elsevier B.V., 2025) Mukhtar, Maria; Goud, Burragoni Sravanthi; Ali, Zeeshan; Shaid, Muhammad Waleed; Naz, Bushra; Ain, Qurat Ul; Assiri, Mohammed A.; Sönmezoğlu, Savaş; Rajpar, Altaf Hussain; Kim, Jae Hong; Aftab, Sikandar
    Recently, metal halide perovskites have engrossed a lot of attraction in the field of developing optoelectronic technologies due to their special optical-electronic characteristics. The toxicity of lead (Pb) based perovskites has developed a major obstacle that restricts their widespread use, despite the fact that they seem to be rising stars in optoelectronic devices. To overcome this hurdle, Pb-free substitutive perovskites have earned growing interest because of their theoretically remarkable environment friendly optoelectronic properties besides compromising stability and enactment. They are not only gaining attention for applications in solar devices but their properties make them an ideal candidate for many other demanding applications. To elucidate the applicability of eco-friendly perovskites in numerous applications, the present article provides an extensive overview of current developments in eco-friendly perovskites in a range of contemporary applications outside of photovoltaics. An overview of these Pb-free perovskites' crystal structure and chemical variety is initially presented. For a number of purposes like artificial synapses, light-emitting diodes, resistive switching memory, photodetectors, and displays, a methodical review of lead-free perovskites is presented in this article. The demonstration of photocatalysis, radiation detection, imaging, sensors, thermoelectric and piezoelectric energy harvesting, and more is crucial. Pb-free perovskite future development prospects and challenges in the aforementioned fields are described, that are thought to be essential for accelerating the profitable adoption of above-mentioned cutting-edge technologies. © 2025 Elsevier B.V.

    Perovskite quantum dots: Fabrication, degradation, and enhanced performance across solar cells, optoelectronics, and quantum technologies
    (John Wiley and Sons Inc, 2025) Aftab, Sikandar; Ali, Zeeshan; Hussain, M. Imtiaz; Assiri, Mohammed A.; Rubab, Najaf; Akman, Erdi
    Metal halide perovskites exhibit excellent absorption properties, high carrier mobility, and remarkable charge transfer ability, showcasing significant potential as light harvesters in new-generation photovoltaic and optoelectronic technologies. Their development has seen unprecedented growth since their discovery. Similar to metal halide perovskite developments, perovskite quantum dots (PQDs) have demonstrated significant versatility in terms of shape, dimension, bandgap, and optical properties, making them suitable for the development of optoelectronic devices. This review discusses various fabrication methods of PQDs, delves into their degradation mechanisms, and explores strategies for enhancing their performance with their applications in a variety of technological fields. Their elevated surface-to-volume ratio highlights their importance in increasing solar cell efficiency. PQDs are also essential for increasing the performance of perovskite solar cells, photodetectors, and light-emitting diodes, which makes them indispensable for solid-state lighting applications. PQDs' unique optoelectronic characteristics make them suitable for sophisticated sensing applications, giving them greater capabilities in this field. Furthermore, PQDs' resistive switching behavior makes them a good fit for applications in memory devices. PQDs' vast potential also encompasses the fields of quantum optics and communication, especially for uses like nanolasers and polarized light detectors. Even though stability and environmental concerns remain major obstacles, research efforts are being made to actively address these issues, enabling PQDs to obtain their full potential in device applications. Simply put, understanding PQDs' real potential lies in overcoming obstacles and utilizing their inherent qualities.
